Problems solved by technology

[0002] Due to the actual operation of photovoltaic and wind power new energy power generation systems, there is a high DC voltage in the DC system circuit, and random operation after grid connection will cause side impacts on the quality of the grid, and live operation training has potential safety hazards for personnel, so it is not suitable for installation and wiring exercises. Training environment for fault simulation
[0003] At present, in the training and teaching of mainstream new energy power generation simulation systems in China, real meteorological environment testing equipment and fixed component scales, electrical parameters, etc. are often used. Realize the simulation of new energy power generation systems under different scenarios, different scales and different equipment models by setting the current meteorological environment, number of components, and electrical parameters of equipment at will, so it cannot fully meet the complex application environment in reality, resulting in insufficient training effect
