Brief introduction of wind power generation
Wind energy is a new energy source with great potential. People may still remember that at the beginning of the18th century, a fierce gale swept through Britain and France, destroying 400 windmills, 800 houses, 100 churches and more than 400 sailboats, injuring thousands of people and uprooting 250,000 trees. In terms of uprooting trees, the wind generated10 million horsepower (7.5 million kilowatts; One horsepower equals 0.75 kW)! It is estimated that the wind resources available for power generation on the earth are about 6543.8+000 billion kilowatts, which is almost 6543.8+00 times of the current hydropower generation in the world. At present, the energy obtained by burning coal every year in the world is only one-third of that provided by wind power in one year. Therefore, both at home and abroad attach great importance to the use of wind power generation and the development of new energy.
Attempts to use wind power to generate electricity began as early as the beginning of this century. In the 1930s, Denmark, Sweden, the Soviet Union and the United States successfully developed some small wind power generation devices by applying the rotor technology of aviation industry. This kind of small wind turbine is widely used in windy islands and remote villages, and its power cost is much lower than that of small internal combustion engines. But at that time, the power generation was low, mostly below 5 kilowatts.
At present, it is known that15,40,45,100,225 kw wind turbines have been produced abroad. 1978 65438+1October, the United States built a 200 kw wind turbine in Clayton town, New Mexico, with blades with a diameter of 38 meters, generating enough electricity for 60 households. 1In the early summer of 978, the wind power station put into operation on the west coast of jutland, Denmark, generated 2000 kilowatts of electricity and the windmill was 57 meters high. 75% of the generated electricity was sent to the power grid, and the rest was supplied to a nearby school.
1In the first half of 979, the United States built another world's largest power windmill in Blue Ridge Mountain, North Carolina. This windmill is ten stories high, and its steel blades are 60 meters in diameter. The blades are installed on the tower building, so the windmill can rotate freely and get electricity from any direction; When the wind speed is above 38 kilometers per hour, the power generation capacity can also reach 2000 kilowatts. Because the average wind speed in this hilly area is only 29 kilometers per hour, it is impossible for all windmills to move. It is estimated that even if it is only operated for half a year, it can meet the electricity demand of 7 counties/kloc-0% to 2% in North Carolina.
How to use wind power to generate electricity?
We convert kinetic energy of wind into mechanical energy, and then convert mechanical energy into electrical energy, which is wind power generation. The equipment needed for wind power generation is called a wind turbine. This kind of wind turbine can be divided into three parts: wind wheel (including tail rudder), generator and iron tower. (Large wind farms basically have no tail rudder, and generally only small ones (including domestic ones) will have tail rudder. )
The wind wheel is an important part that converts the kinetic energy of wind into mechanical energy. It consists of two (or more) propeller-shaped impellers. When the wind blows to the blades, the aerodynamic force generated on the blades drives the wind wheel to rotate. The material of the blade requires high strength and light weight. At present, it is mostly made of FRP or other composite materials (such as carbon fiber). There are some vertical wind wheels, S-shaped rotating blades and so on. Its function is the same as that of traditional propeller blades. )
Because the rotational speed of the wind wheel is relatively low, and the magnitude and direction of the wind force often change, this makes the rotational speed unstable; Therefore, before driving the generator, it is necessary to add a gear box to increase the speed to the rated speed of the generator, and add a speed regulating mechanism to keep the speed stable, and then connect it to the generator. In order to make the wind wheel always aim at the wind direction to get the maximum power, it is necessary to install a tail rudder similar to a wind vane behind the wind wheel.
The iron tower is the frame supporting the wind wheel, tail rudder and generator. It is generally built relatively high, so as to obtain larger and more uniform wind force, and at the same time, it has enough strength. The height of the tower depends on the influence of ground obstacles on wind speed and the diameter of the wind wheel, which is generally within the range of 6-20 meters.
The function of the generator is to transfer the constant rotation speed obtained by the wind wheel to the power generation mechanism to run at a constant speed through the speed increase, so as to convert mechanical energy into electrical energy.
How big is the wind to generate electricity?
Generally speaking, the third-grade wind is valuable. However, from an economic and reasonable point of view, the wind speed is greater than 4 meters per second for power generation. According to the measurement, when the wind speed of a 55kW wind turbine is 9.5m per second, the output power is 55kW. When the wind speed is 8 meters per second, the power is 38 kilowatts; When the wind speed is 6 meters per second, it is only 16 kw; When the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the greater the wind, the greater the economic benefits.
In China, there are many successful small and medium-sized wind power generation devices in operation.
China is rich in wind resources, and the average wind speed in most areas is more than 3 meters per second, especially in the northeast, northwest and southwest plateaus and coastal islands, and the average wind speed is higher. In some places, it is windy for more than one third of the year. In these areas, the development of wind power generation is very promising.
The principle of wind power generation
The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed through the speed reducer to promote the generator to generate electricity. According to the current windmill technology, power can be generated at a breeze speed of about three meters per second (the degree of breeze). Wind power generation is becoming a worldwide craze. Wind power generation has no fuel problems, radiation and air pollution.
Wind power generation is very popular in Finland, Denmark and other countries; China also strongly advocated it in the western region. Small wind power generation system is very efficient, but it is not just composed of a generator head, but a small system with certain scientific and technological content: wind generator+charger+digital inverter. A wind turbine consists of a nose, a rotor, a tail and blades. Each part is very important, and the function of each part is as follows: the blade is used to receive wind power and convert it into electric energy through the nose; The tail wing makes the blades always face the direction of the incoming wind to obtain the maximum wind energy; The rotor can make the nose rotate flexibly and realize the function of adjusting the direction of the tail; The rotor of the handpiece is a permanent magnet, and the stator winding cuts the magnetic field lines to generate electric energy.
Due to the unstable air volume, the wind generator outputs 13 ~ 25V alternating current, which must be rectified by a charger, and then the battery is charged, so that the electric energy generated by the wind generator becomes chemical energy. Then the chemical energy in the battery is converted into AC 220V commercial power by an inverter power supply with a protection circuit to ensure stable use.
Usually people think that the power of wind power generation is completely determined by the power of wind turbines, and they always want to buy a bigger wind turbine, which is not correct. At present, wind turbines only charge batteries, which store electric energy. The size of the power that people finally use is more closely related to the size of the battery. Strength mainly depends on the air volume, not just the strength of the nose. In the mainland, small wind power generation opportunities are more suitable than large ones. Because it is easier to be driven by small air volume to generate electricity, a continuous small wind will provide more energy than a temporary strong wind. When there is no wind, people can still use the electric energy brought by the wind normally, that is to say, a 200W wind turbine can get 500W or even 1000W or more power output through the cooperation of a large battery and an inverter.
The use of wind turbines is to constantly turn wind energy into standard commercial electricity for our families, and its saving degree is obvious. A family's annual electricity consumption only needs the price of battery liquid in 20 yuan. However, the performance of today's wind turbines has been greatly improved compared with a few years ago. Previously, it was only used in a few remote areas. Wind turbines are directly powered by 15W bulbs, which are flickering and often damage the bulbs. Nowadays, due to technical progress and the use of advanced chargers and inverters, wind power generation has become a small system with certain scientific and technological content, which can replace normal commercial power under certain conditions. Mountain areas can use this system to make a street lamp that doesn't cost money all the year round; Expressway can use it as a road sign light at night; Children in mountainous areas can study by themselves under fluorescent lamps at night; Wind turbines can also be used on the roofs of small high-rise buildings in cities, which is not only economical, but also a real green power source. Household wind turbines can not only prevent power failure, but also increase the interest of life. In tourist attractions, frontier defense, schools, troops and even backward mountainous areas, wind turbines are becoming a hot spot for people to buy. Radio enthusiasts can use their own technology to serve the people in mountainous areas in wind power generation, so that people can watch TV and use electricity for lighting in synchronization with the city, and they can also make themselves rich through labor.
Wind Energy Resources in China
I. Overview
China is rich in wind energy resources, and the exploitable wind energy reserves are about 654.38+0 billion kW, of which the onshore wind energy reserves are about 253 million kW (calculated by the data of land height 10m), and the offshore wind energy reserves are about 750 million kW, accounting for 654.38+0 billion kW. By the end of 2003, the national installed capacity was about 567 million kilowatts.
Wind is one of the pollution-free energy sources. And it is inexhaustible. For coastal islands, grassland and pastoral areas, mountainous areas and plateau areas with water and oil shortage and inconvenient transportation, it is very suitable and promising to use wind power according to local conditions.
Introduction of China Independent Intellectual Property Products in Wind Power Industry;
In the 1990s, China's independent power supply system mainly used horizontal axis wind turbines and solar photovoltaic systems for power supply, which were mainly used in communication base stations, border posts, island troops and other special occasions. It is mainly the logistics support system of the army.
After a period of application, many problems have been found. If the equipment is seriously damaged in the typhoon; The noise is loud, which affects the normal rest of personnel; Interference with communication equipment makes some equipment unable to operate normally. The occurrence of these problems has affected the normal communication of the troops.
200 1, in order to solve these problems, relevant units were convened for discussion, and Shanghai Moss Electronic Equipment Co., Ltd., as a supporting manufacturer of military communication products, was also invited. After the meeting, after a certain period of investigation and study, MUCE Company proposed to undertake the important task of tackling this scientific research problem, which was agreed by the military and local leaders, and issued instructions to come up with a technical scheme and make a prototype as soon as possible.
With the cooperation of a group of experts from Xijun Electric Power, Xi Jiaotong University, Shanghai Fudan University, Shanghai Tongji University and other universities, Shanghai Mosi Electronic Equipment Co., Ltd. successfully developed the world's first new (H-type) vertical axis wind turbine in less than a year, and successfully installed it, and gained basic data and practical experience. (This has also become the birth day of the world's first new vertical axis wind turbine. In the following year, MUCE made many improvements and tests on the products. At the end of 2002, the product passed all the tests and met all the design requirements.
Since the end of 2002, MUCE has installed more than 60 sets of vertical axis wind turbines and wind-solar complementary systems in the army, which has made immortal contributions to the stability of national defense!
The wind-light complementary street lamp power supply system produced by Shenzhen Chengyuan Company is a new road lighting system that comprehensively utilizes solar energy and wind energy. Due to the limitation of time and geography, it is difficult for a single solar or wind energy heating system to utilize solar and wind energy resources all day. However, solar energy and wind energy are highly complementary in time and region. When the light is strong during the day, the wind is weak, and when the light is weak at night, the wind energy is enhanced due to the great change of the surface temperature difference. The complementarity of solar energy and wind energy in time is the best matching of resource utilization of wind-solar complementary street lamp power supply system. The system is energy-saving, environmentally friendly, renewable and inexhaustible, and will become the mainstream to replace other road lighting systems in the future. When the system is working, the solar collector collects solar radiation energy to generate electricity (during the day), and transmits it to the power control system for storage and distribution through special lines. Wind turbines use wind energy all day, converting it into electric energy, and then rectifying it through the controller to charge the battery pack.
A New Wind Energy Conversion Mode —— Runoff Double Wheel Effect
Runoff double-wheel effect or double-wheel effect is a new type of wind energy conversion.
First of all, it is a two-wheel structure. Compared with the horizontal axial fan, it is radial. Like the existing vertical shaft fan, the blades are arranged along the long axis and rotate directly by the thrust of the wind. Because the blades on both sides of the single-wheel vertical axis wind turbine are exposed to the wind at the same time, the torques are opposite and cancel each other, and the output torque is very small. Designed as a two-wheel structure, it is close to the installation, and the synchronous operation changes the dependence of the original vertical shaft torque output on the hydrodynamic shape of the blade into the eddy current force generated by the rotation between the two wheels, and the two wheels help and push each other; The reverse airflow between the two wheels can be shielded from each other and then distributed to the outer sides of the two wheels in turn, so that the outer sides of the two wheels can get superimposed airflow, so that the linear speed of the outer edges of the two wheels can be higher than the wind speed. The mutual assistance of this two-wheel structure actively utilizes the characteristics of wind power and produces a "two-wheel effect".
Compared with some fans with single-wheel structure, the design of passively reducing the rotating reset resistance of the impeller, such as external shielding method and movable pitching moment, embodies the characteristics of actively using wind power. Therefore, the invention not only has practical function and promotes the research and development of wind energy utilization, but also has new significance in fluid mechanics. It opens up a new space for the development of wind energy and is a fundamental invention. This kind of double-wheel fan has the obvious characteristics of simple design, easy manufacturing and processing, low rotating speed, low center of gravity, good safety, low operating cost, convenient maintenance and no noise pollution. , can be widely popularized, meets the needs of energy conservation and emission reduction in China, and has a huge market prospect.
Overview of wind energy market
As a clean and renewable energy, wind energy has attracted more and more attention from all countries in the world. It has a lot of wind energy. The global wind energy is about 2.74× 109MW, of which the available wind energy is 2× 107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are very large and widely distributed, and the wind energy reserves on land alone are about 253 million kilowatts.
With the development of global economy, the wind energy market has also developed rapidly. Since 2004, the installed capacity of global wind power generation has doubled, and between 2006 and 2007, the installed capacity of global wind power generation has expanded by 27%. In 2007, there were 90,000 MW, and by 2065,438+00, this figure will be 654,380+600,000 MW. It is predicted that the world wind energy market will grow at an annual rate of 25% in the next 20-25 years. With the development of technology and environmental protection, wind power generation can compete with coal-fired power generation in business.
During the Tenth Five-Year Plan period, China's grid-connected wind power developed rapidly. In 2006, the cumulative installed capacity of wind power in China has reached 2.6 million kilowatts, making it one of the major wind power markets after Europe, the United States and India. In 2007, the scale of wind power industry in China continued to explode. By the end of 2007, the cumulative installed capacity of China was about 6 million kilowatts. In August 2008, the total installed capacity of wind power in China has reached 7 million kilowatts, accounting for 1% of the total installed capacity of power generation in China, ranking fifth in the world, which also means that China has entered the ranks of renewable energy countries.
Since 2008, the domestic wind power construction boom has reached a white-hot level. By the end of 2008, the scale of wind power may reach 10 million kilowatts, and the cumulative installed capacity will reach 20 million kilowatts by 20 10.
The development prospects of new energy power generation industries such as wind power in China are very broad, and it is expected that they will maintain high-speed development for a long time to come. At the same time, with the gradual maturity of technology, the profitability will be steadily improved. In 2009, the total profit of this industry will maintain rapid growth. After the rapid growth in 2009, it is estimated that the growth rates of 20 10 and 20 1 1 will slow down slightly, but the growth rate will reach over 60%.
With the development of wind power at this stage, the cost performance is forming a competitive advantage with coal-fired power and hydropower. The advantage of wind power is that every time the capacity is doubled, the cost will be reduced by 15%. In recent years, the growth of wind power in the world has remained above 30%. With the localization of wind power installed in China and the expansion of power generation scale, the cost of wind power is expected to drop again. Therefore, wind power has become a gold rush place for more and more investors.
Prospects of wind power generation
China's new energy strategy began to focus on the development of wind power. According to the national plan, the installed capacity of wind power generation in China will reach 20-30 million kilowatts in the next 15 years. Based on the investment of 7,000 yuan per kilowatt of installed equipment, the future wind power equipment market scale will reach 654.38+0.40 billion yuan to 265.438+0.00 billion yuan.
