1. Authenticity: The power system model has the same dynamic and static characteristics as the actual power system, and the actual power system is reproduced as truly as possible for training. 2. Consistency: The environment of the trainees' platform should be as consistent as possible with the environment of the actual power grid dispatching control center, so that the trainees have a sense of presence when receiving training. 3. Flexibility: You can flexibly control the training at the teacher's desk and flexibly simulate various operations and faults of the power system.
