The electric power industry is the most important basic energy industry in the development of the national economy, the first basic industry of the national economy, the basic industry related to the national economy and people's livelihood, and the priority development in the economic development strategies of all countries in the world. As an advanced productive force and basic industry, electric power industry plays an important role in promoting national economic development and social progress. It is closely related to social economy and social development. It is not only a strategic issue related to national economic security, but also closely related to people's daily life and social stability. With the development of China's economy, the demand for electricity is expanding, and the expansion of the electricity sales market has stimulated the development of the whole power production.
It is reported that the first 330kv transmission line was built in 1974, from Liujiaxia Hydropower Plant in Gansu Province to Guanzhong area in Shaanxi Province. 198 1 year, the first 500 kv transmission line was built, from Meng Yao thermal power plant to Wuhan. The transmission voltage level of the power system is 500/220/ 1 10kv except the northwest power grid. The power grids of all provinces in China have formed a 220 kV power grid, and the power grids of North China, Northeast China, East China, Central China and South China have built 500 kV large-capacity transmission lines and inter-provincial tie lines, which will gradually form a backbone network interconnected across regions. The 750 kV transmission project in the northwest under construction marks that the transmission voltage level of China's power grid will be raised from the current 500 kV to 750 kV, achieving a historic leap. In addition to EHV transmission, a 500kv DC transmission line from Gezhouba to Shanghai Nanqiao was built at 1988, with a total length of 1080km and a transmission capacity of 120*kw, which interconnected the two major power systems in Central China and East China to form a cross-regional joint power system. In these power construction projects, the substation automation system of ultra-high voltage (220kv/330kv/500kv/750kv) plays an important role.

Tian Yun Substation belongs to Zhuzhou Electric Power Bureau of State Grid. Zhuzhou Electric Power Bureau is a sophomore power supply enterprise directly under Hunan Electric Power Company, responsible for the power supply of Zhuzhou City and its four counties (cities), with a power supply area of 1 1420 square kilometers and a population of 3,570,500. Zhuzhou Electric Power Bureau has four county-level electric power bureaus, namely Zhuzhou County, Liling County, Youxian County and Chaling County, five professional management offices for substation management, line management, power consumption management, dispatching management and metering management, Tianyun 500 kV substation, Gaoxin Electric Power Co., Ltd. and its subsidiaries. There are 45 substations in the world with a total capacity of 353.875 KVA, and the capacity of Tianyun 500 KVA substation under its jurisdiction reaches 1.5 million KVA, which has entered the ranks of super-large substations in China and is one of the core components of Hunan rhombic EHV ring network. At present, there are transmission lines 1297.57 km, distribution lines 5 127.58 km, and more than 40,000 high and low voltage users. The original value of global fixed assets is 65.438+0.47 billion yuan, and the net value is 684 million yuan.

Under the new situation of deepening reform and market competition, Zhuzhou Electric Power Bureau takes "creating two benefits and cultivating first-class talents" as its strategic goal and follows the cross policy of "development, reform, management, benefit and service".
Write a new chapter for the power grid construction in Zhuzhou area.
From the historical development, power grid can be divided into four stages: direct distribution of power plants to urban power grid, provincial power grid, inter-provincial power grid and cross-regional joint power grid. With the continuous growth of electricity consumption, the construction of large-scale hydropower, thermal power and nuclear power, the imbalance of power supply and load between regions and the need of economic dispatch, it is inevitable to develop transmission and networking. The voltage level rises gradually. From the initial low voltage level of 6- 10kv to 35kv, 1 10kv and 220kv, it has developed into ultra-high voltage power grids of 330kv, 500kv and 750kv, and there is a tendency to continue to rise.
workshop practice
On October 3rd, XX/KLOC-0, 65438, all students majoring in public utilities came to Tianyun 500 kV substation in Zhuzhou. When I came to Tian Yun Substation, I saw two high-voltage tower lines leading to the substation from a distance. As soon as I entered the gate, two giant transformers in the yard came into view. After giving us safety education, the director began to show us around several important places, such as external transformer equipment, high voltage room and main control room. External transformer equipment is divided into main transformer equipment and standby transformer equipment. The standby transformer equipment is activated when the main line fails or the equipment is overhauled, which improves the working efficiency. In order to prevent power failure caused by problems in the power station. Substation adopts double power supply station transmission measures. Because two different power plants independently supply power to the substation through two lines. During normal operation, the substation uses one power supply, and the other power supply is enabled when the power supply is cut off. After the external high-voltage electricity enters the substation, it is finally connected to the input end of the transformer through the isolating switch, voltage transformer and current transformer. When the two transmission lines ab work normally, the A line is connected to the A transformer through the disconnector. When transformer A fails, line A can be connected to transformer B, and line B can also supply power to transformer A or transformer B to ensure the normal operation of the railway. Voltage transformer is used to measure power supply voltage, and current transformer is used to measure power supply current. When they are used together, electricity can be measured.
The transformer can convert external 500kv high-voltage electricity into 1 10kv low-voltage electricity required by the locomotive. Because of the high voltage and power of the transformer, the transformer generates a lot of heat, so how to reduce the temperature of the transformer to ensure its normal operation is very important. In order to reduce the temperature, many heat sinks are installed on each transformer. When the main body temperature exceeds 55 degrees Celsius, the fan at the lower part of the radiator will automatically start and trip at 85 degrees Celsius, indicating that the line is out of order and plays a role in temperature protection. In order to prevent short circuit, 25# oil is installed in the main body of the transformer, and the main body is equipped with an oil storage tank, which can supply oil to the main body to supplement consumption at any time. The gas meter is used to prevent excessive gas from being generated in the main body, and alarm the administrator in time to prevent the transformer from being damaged.
After that, we came to the high pressure chamber. The high pressure chamber is clearly divided into an input end and a feed-out end. The internal equipment is separated by many iron bars, many of which are imported, with automatic power transmission and trip protection, and have not failed for ten years. In the main control room, two technicians monitor the working state of the main control equipment at any time. The main control equipment is huge in size and perfect in function, and has many functions such as fault display, fault analysis and automatic protection, which brings great convenience to management and operation. When tripping, the green light flashes and the alarm bell rings. When the railway line is interrupted, the distance between the outage point and the substation can be displayed on the display screen of the main control board, which brings convenience for timely maintenance. Finally, we have a general understanding of the structure and working state of the whole substation, and a more intuitive and clear understanding of it.
Then we followed the director to the conference room, and he explained the operation process and some basic modes of Tian Yun substation.
Under normal circumstances, after the power reaches the 500 kV substation through the transmission line, it is converted to the 220 kV level through the transformer, and then to the 1 100 kV level through the transformer, and the voltage is reduced again through the 1 100 kV substation, and finally it is converted into residential electricity through the common transformers on the street. At this point the voltage has dropped to 220.
Then came to main control room, including microcomputer monitoring system, power system communication system and substation management system. The main control room of Mengshan Substation is composed of six computers: video monitoring system, fault recording system, monitoring background 2, monitoring background 1 and five prevention systems, all of which are the products of Nanrui Group, a relatively advanced electrical industry in China, and can be said to be the most advanced technology in China. Monitor the operation of the whole substation in the main control room, and use computer technology to carry out early warning, analysis and troubleshooting, control and safe operation locking, display and tabulation, time sequence recording, accident recall, information remote transmission, operation, operation and accident handling guidance, man-machine contact, technical management of operation, self-diagnosis, self-recovery and automatic switching.
The stationmaster told us that there are only five people on duty in the whole main control room every day. It can be said that the construction and implementation of regional control center has achieved economic benefits in reducing staff and increasing efficiency, improving operation efficiency and reducing operation and maintenance costs. From the perspective of long-term benefits and power grid development, with the increasing number of interconnected substations, the economic benefits of substations designed in unattended mode will be more significant in reducing engineering investment, operation and maintenance costs and shortening construction period.
In addition, when dealing with accidents, we must be steady (calm), accurate (accurate) and fast, and take measures according to the following principles: limit the development of accidents as soon as possible, eliminate the root causes of accidents, and remove the threat to personal and equipment safety; Do everything possible to keep the equipment running and ensure that users use electricity; Resume power transmission to customers without power supply as soon as possible; Adjust the operation mode of power system and restore its normal operation. Contact reporting system and reporting materials during and after the accident. The dispatcher on duty in power system leads the personnel on duty in each substation to deal with the accidents in the system. When an accident occurs, the personnel on duty in the substation shall report the relevant information to the dispatcher on duty, the dispatcher in the sub-bureau and the stationmaster in time. According to the reported situation, the dispatcher decides to analyze, make an accident handling decision and give orders. The report of the personnel on duty must be timely, comprehensive and accurate. False positives and false negatives will have adverse consequences for handling accidents. An emergency can be dealt with first and then reported. When the accident occurs, the contact between the substation and the dispatching is interrupted, and the personnel on duty shall handle it according to the regulations. After the communication is restored, the accident situation and treatment process should be reported in detail immediately, and the incident should be recorded.
Four. internship summary
Through this internship, I learned about the composition of substation electrical equipment, the layout and characteristics of distribution equipment, and the benefits of safe clearance. Understand the layout of control screen and protection screen and the overall layout of main control room. Working in a substation, safety is the most important thing. Keeping in mind the practical policy of "safety first, prevention first", strengthening the study of "safety regulations" and improving safety awareness are our compulsory courses. "Substation safety is no small matter" has been deeply imprinted in the hearts of every classmate. I gained a lot in this internship. These are intangible assets that will accompany me all my life. It can be seen from this visit that the management of substation can be said to be a militarized management mode. Before I left, I watched the transmission lines transmit electric energy to thousands of households, which brought us the light and strength to conquer nature. In addition, we also learned some experience in dealing with people and working in society from talking with the webmaster, which made me understand how to create extraordinary in the ordinary.

There was a time:
2. Location:
Three internships:
4. Internship materials
(A) to understand the overall situation of the power system
On the morning of X, all our students got together, and xu teacher gave a general explanation of the whole power generation system and got to know the power generation process.
Power plants in China mainly include thermal power plants, hydropower plants and nuclear power plants.
(1) electric energy production process of thermal power plant
The energy used by thermal power plants in China is mainly coal, and the main power plant is condensate gas power plant. The whole production process can be divided into three systems: the chemical energy of fuel is converted into heat energy in the boiler combustion, and the water in the boiler is heated to become steam, that is, the combustion system. It is mainly composed of coal transportation, wind smoke and ash. The steam-water system is mainly composed of boilers, steam turbines, condensers, deaerators, heaters and other equipment and pipelines. Convert thermal energy into mechanical energy. The electrical system consists of generator, excitation device, auxiliary power system and booster station.
(2) Hydroelectric power plants
Hydroelectric power plants are also called hydropower stations. A factory that converts the potential energy and kinetic energy of water into electrical energy. The production process is: take water from a high river or reservoir. Using the pressure or flow of water to make the turbine rotate, the water energy is converted into mechanical energy, and then the turbine drives the generator to rotate, and the mechanical energy is converted into electrical energy.
(3) Nuclear power plants
Nuclear power plant is referred to as nuclear power plant for short. It uses the thermal energy generated by the fission chain reaction of fuel in the reactor core to convert the thermal energy into mechanical energy and then into electrical energy according to the power generation mode of thermal power plants.
There are other power plants in China, such as wind farms. Geothermal power plant. Tidal power station, etc.
(2) High-voltage corridor
On the afternoon of X, our people visited the high-voltage corridor from the west gate of the school to Longyuan Lake. The main line is 10KV transmission line, and there are two lines, namely Li Wanzuo Line and Li Line. It also supplies power for our school. This line is not a * line, because it is more elegant and lower than the 1 10KV line, and the line is close to the ground, so people or cars will not be hurt, so the * line is not used.
Through this day's study, I learned the following knowledge:
1. Main equipment of transmission line
Insulators of transmission lines, corresponding metal wires and overhead ground wires are suspended on towers, connecting power plants and substations to realize power transmission.
Conductor A: Steel-cored aluminum stranded wire or steel-cored aluminum stranded wire is commonly used at present. In order to improve the transmission potential of the line, the split conductor type consisting of four or two conductors per phase is usually used.
B Overhead ground wire is mainly used for lightning protection, which can also reduce the potential power supply current in case of power frequency overvoltage and asymmetric short circuit. Composite overhead ground wire with optical cable and communication function.
C insulator: an object that insulates and fixes the conductor and hangs it on the tower. Commonly used are disc-shaped porcelain insulators, disc-shaped glass insulators and rod-shaped suspension composite insulators.
D. Dry frame: supporting overhead line conductors and overhead ground wires. The distance between the electrodes in contact in this exercise is 50 meters.
The high-voltage transmission line adopts * line transmission. If alternating current is transmitted, hollow transmission lines are generally used. There are two wires at the top of the high voltage transmission line as lightning protection wires, and the three-phase electricity transmitted is split. There is an insulator at the connection between the line and the dry frame to fix the line to prevent the wire from being twisted off due to frequent jitter. There are many iron rings on the transmission line for hanging wires. Communication lines often borrow poles laid by transmission lines to save capital investment. They run in parallel to minimize the interference between them. When the transmission line encounters obstacles that are difficult to clear, use underground cables.
(3) Power distribution equipment
From October to October in X year, we visited the power distribution equipment and central air conditioning in the school building.
The electricity in our school is imported from Li Wan's 10KV power supply line, passing through circuit breakers and disconnectors. Transformers and high voltage switchgear. The following parts should be analyzed:
The power distribution device is an integral device consisting of switching appliances, protection and measuring appliances, bus bars and necessary auxiliary equipment according to the connection mode of the main electrical wiring. Its function is to understand and distribute electric energy under normal operation, but when the system fails, it can quickly remove the failed part and maintain the normal operation of the system.
The first thing I saw were two power transformers, which were arranged on the ground and installed on the transformer foundation. Transformer foundation generally adopts double beams supplemented by tracks, and the track gauge is equal to the rolling center of transformer. The distance between the main transformer and the building shall not be less than1.25m. The building within 5m from the transformer shall have no doors, windows and ventilation holes below the total height of the transformer and within 3m on both sides of the verandah.
After entering the distribution room, the high-voltage switchgear in our school adopts handcart type. It adopts single bus configuration and consists of handcart room and electrical instrument room. Bus room and outlet room. Both the circuit breaker and the operating mechanism are installed on the trolley, and the upper part of the front part of the circuit breaker handcart is the propulsion mechanism. When the handcart is in the working position, the circuit breaker is communicated with the bus and socket through the isolation plug and the relay instrument room. Measuring instruments. Signal relay and relay protection are installed on the instrument door of the cabinet. There are relays, wiring boards, fuses and electric energy meters in the cabinet. The bus room is located at the rear upper part of the switch cabinet, and there are buses and static isolating contacts in the cabinet. The outlet room is located below the back of the cabinet, and the outlet side is equipped with electrostatic isolation contacts and current transformers. Lead-out cables and grounding switches, etc.
The low-voltage distribution panel has a door, and the frame is welded by angle steel and thin steel plate. In terms of maintenance, the upper panel is equipped with measuring instruments, the middle panel is equipped with the operating handle and control button of the knife switch, and the lower panel is equipped with relays, secondary terminals and electric energy meters. Busbars are arranged at the top of the screen with protective cover, other electrical components are installed behind the screen, and partitions are installed between the screens, which can limit the fault range.
Busbars and frames. Busbars of outdoor distribution equipment include soft bus and hard bus, and the soft bus is steel-core aluminum stranded wire. Flexible bus pipes and split conductors. The position of high voltage circuit breaker in power distribution equipment. The layout of circuit breakers must be reasonably selected according to the main wiring, site topography, overall layout and outlet direction. Circuit breakers are arranged in two ways: low position type and high position type. Lightning arresters are also arranged in high and low positions. The disconnector and transformer are arranged in high places. Cable trench can meet the requirement of the shortest path taken by cable. In a word, the power distribution device should meet the requirements of ensuring reliable operation, convenient operation, inspection and maintenance, ensuring the safety of staff, striving to improve economy and having the possibility of expansion.
Later, we visited the central air-conditioning room of our school. The air conditioner is mainly controlled by a host computer connected with a plurality of terminals through hot and cold water pipelines. Its main component is the compressor. It completes the process of gas compression and transportation by changing the volume of gas, and the refrigeration system is mainly divided into compressors. Condenser. Evaporator. A compressor compresses a refrigerant into a high-pressure saturated gas, and this gaseous refrigerant is condensed by a condenser. After passing through the throttling device, it enters the evaporator for cooling and exchanges heat with the cooled medium. After heat exchange, the refrigerant in the serpentine tube of the evaporator becomes low-pressure steam, returns to the compressor, and is compressed again, thus completing the refrigeration system. The heating system is basically the same principle, but in the opposite way. The central air conditioning in our school is mainly used by the school library, the administration building and some professor buildings. Its supply system feels imperfect. Especially in summer, on the fifth and sixth floors of the library, you can't feel the air conditioning. According to the master, it is because the power system is out of order.
(4) Yucun Substation
On the morning of X, led by the instructor, we walked to Yucun Substation in Jiaozuo City. As soon as I entered the entrance, I saw many pole stands and many complicated power distribution devices. Because of the large number of visitors, we first visited the voltage corridor next to the substation. The voltage corridor has low-voltage power supply lines and high-voltage power supply equipment. It is specially used in electrician training, so there are only models and no power supply. The high-voltage line has seven wires, and the top two wires are lightning protection devices. There is a zero line. Three-phase power supply line. There are four low-voltage lines, using three-phase four-wire system. There are three yellow, red and green insulators on the transformer. The insulators on the high voltage side are relatively high, and there are four insulators on the low voltage side, three of which are dedicated to power supply and the other one is used for neutral line. Because of the large current, the power line on the low voltage side is thinner than that on the high voltage side. After visiting the line, I officially entered the substation under the leadership of the master. Since the power supply lines are in use, we will watch and ask the master if we have any questions.
First, we learned about the transformer in the substation. Its high and low voltage in the power grid is 1 10/ 10KV, and it is an autotransformer with neutral point grounded. The high-voltage side adopts star connection and the low-voltage side adopts angle connection. Because the transformer will generate a lot of heat during operation, its heat mainly comes from oil immersion, and its working process is that heat is transferred to transformer oil from the surface of winding and iron core through convection, which is about 20~30% of the temperature rise of winding to air. The hot oil near the winding and the iron core transfers heat to the inner surface of the oil tank or radiator by convection, and the heat from the inner surface of the oil tank or radiator is dissipated to the outer surface by conduction. Heat is dissipated into the surrounding air through convection and tank wall radiation, accounting for a large proportion.
Then we visited the wiring part of the substation. High-voltage circuit breakers and disconnectors are important switching appliances in the main electrical system of substations, which are mainly used for normal operation, switching operation modes, connecting equipment or lines to the power grid or quitting operation, and playing a control role. When the equipment or line fails, it can quickly cut off the faulty circuit to ensure the normal operation of the fault-free part and play a protective role. High-voltage circuit breaker is the most perfect equipment for switching electrical appliances. Its characteristic is that it can cut off the load current and short-circuit current of electrical appliances. The main function of high-voltage disconnector is to ensure the safety of high-voltage electrical appliances and equipment in maintenance work. It is not allowed to cut off and input the load current with jade, and it can only be used for some switching operations that do not produce strong arc.
The working principle of electromagnetic current transformer is similar to that of transformer, which is characterized in that the primary winding is connected in series in a circuit with fewer turns, so the current safety of the primary winding depends on the load current of the circuit to be tested, and has nothing to do with the secondary current. The current coil impedance of the instrument connected with the secondary winding of current transformer is very small, so under normal circumstances, the current transformer runs in a near short-circuit state. The working principle of electromagnetic transformer is the same as that of transformer, which is characterized by small capacity, similar to a small capacity transformer. The voltage coil impedance of secondary measuring instrument and relay is large, and the transformer runs near no-load state. In short, the transformer is the sensor for the secondary equipment to obtain the information of the electrical primary circuit.
Let me talk about the overall understanding of the substation. Substation is an important part of power system. With the development of science and technology, substation automation has been realized, and automatic means such as data acquisition and monitoring, alarm processing and voltage/reactive power integrated control have been adopted, which reduces manual intervention and improves operation and maintenance efficiency. However, the protection of substation also needs to be improved. Its main protection system includes lightning protection and overvoltage protection of information system. Yucun substation has four large lightning rods. The lightning arrester is installed in the substation, mainly to limit the overvoltage when lightning waves invade. The lightning rod is installed in the substation, which is also called incoming line protection.
Yucun substation was built late, with two large transformers. In order to prevent the increase of electricity consumption in the future, a backup transformer installation platform was built at the beginning of the design, and the circuit was mainly repaired manually when necessary, because the power supply system of the substation realized automatic control. Through the master's explanation, I have a further understanding of the substation equipment. Understand the functions of each equipment in substation.
Tisso
My name is xxx, and I am employed in xx this year. I have learned a lot during my months in the company. Through contact with people and things, I understand my own shortcomings and constantly correct them. During this period of work, with the leadership of the company leaders and the help of my colleagues, I have achieved good results in my work and study. Now I will summarize my work and study in a few months.
I. Working conditions
With infinite yearning for life, I walked into the 35kvxx substation. After the transformation, our station has two main transformers, which are responsible for the power supply of two and a half towns. Many people think that the work of substation operation duty is simply reading meters, patrolling equipment, handling work tickets and switching; However, only those who have done it can understand that as a duty officer with a strong sense of responsibility, it is far from enough to complete the above work to ensure the safe and stable operation of a substation; To ensure the safe operation of the power grid, the most important thing is to be good at analyzing and handling the defects of equipment, so that the defects and hidden dangers can be controlled or eliminated in time. The rainstorm in June brought abundant rain around the high-pressure room of our station. In order to prevent rainwater from invading indoor power distribution equipment and causing undue accidents, our class checked in the rain, dredged the blocked drainage system in time, and installed water baffles to prevent rainwater from invading. Then the indoor wall is plastered with waterproof mortar, and finally the inspection is strengthened. Through effective measures, I survived the thunderstorm in June safely.
During the probation period, on the one hand, I strictly abide by the company's rules and regulations, do not be late or leave early, strictly demand myself and consciously abide by various work systems; On the other hand, diligence, initiative and hard work; While completing the work assigned by the leader, actively assist other colleagues in their work, learn modestly in the process of work, and improve their potential in all aspects; In addition, I am an honorable correspondent. In addition to the monthly newsletter, I am also responsible for the technical training of this site, trying my best to assist the webmaster and enrich my work experience. Through monthly training, I have improved the cohesion of my station staff to some extent. In the details of the work, I see that the company is getting bigger and stronger. With the current trend, I can foresee that the company will have a brilliant tomorrow. As a newcomer, what I can do now is to work hard to make myself sweat in an ordinary post and glow with youth and enthusiasm; Let yourself get more exercise at the grassroots level.
Second, the learning situation
This is the stage where I study hard. Practice report of substation. Every colleague in the company is my teacher, and their rich experience and work behavior are a valuable asset to me. I remember when I first arrived at the substation, I was surprised at everything in the substation. Because I am not a major in substation operation, I have limited knowledge of equipment operation management, but I have benefited a lot under the careful guidance of webmasters and shift supervisors. With full work enthusiasm, I gradually became familiar with the operation of the equipment. Although I am only a beginner, I am as enthusiastic about my work as other young people. In order to improve my knowledge and potential in my job as soon as possible and give full play to my subjective initiative, I use my spare time to find relevant materials for study. In a short period of one year, through the combination of theory and practice, I have a real understanding of the basic equipment of the substation, laying the foundation for future work.
As an intern, I often think about how to cooperate with the webmaster to do a good job in management. My personality is in the period of "creating first-class", so I often ask new and old webmasters for advice.
I stayed in the substation for a year, met many colleagues, and also understood what "personnel" is. "Dealing with people" is a profound knowledge for both society and units. For this profound knowledge, I, a layman, can only say, "Be honest and do well!"
Along the way, I participated in the maintenance and defect treatment of 35kv substation. In the process of learning from the person in charge, I deeply felt my lack of technology and the hardships of grassroots work! In order to better adapt to the work, I went to Jiangxi Electric Power Vocational and Technical College to study power system and its automation.
Third, summary.
As a young worker, my future career is still very long, and there are still many opportunities to learn. As a Communist Youth League member, it has always been my dream to join the Communist Youth League. To this end, I will strive to develop my work and make achievements. In order to achieve my goal at an early date, I ask myself to work hard, continue my advantages, correct my shortcomings, fully reflect my life value and contribute to the perfect tomorrow of the enterprise. I hope that through the efforts of all employees of the company, we can push the company to the peak one after another.
