Problems solved by technology
However, at present, there are few platforms at home and abroad that can completely simulate the entire pumped storage unit speed control system and its upper and lower connection parts, and the functions of the existing energy storage unit speed control system simulation platforms are limited to Simulation at the plant-level mechanical and electrical equipment level of the speed control system
[0005] However, due to the lack of development of the governor system model on the existing power system simulation platforms at home and abroad, the functions are generally simple, and it is difficult to perfectly adapt to the application status of the pumped storage unit; It does not include the simulation unit of the monitoring system; it does not have the functions of realizing various tasks such as speed, synchronization, load regulation, and working condition conversion; it can only simulate the power generation process, and cannot simulate the load regulation process of synchronous and pumping conditions; and there is no Power grid simulation module, a few have power grid simulation modules but do not have the function of simulating power grid load frequency characteristics, but can only simply simulate power grid frequency fluctuations, etc.
These are not conducive to the promotion of efficient production
