Description

technical field [0001] The invention relates to the technical field of simulation testing of pumped storage units, in particular to a hardware-in-the-loop simulation testing platform for controllers of variable-speed and constant-frequency pumped storage units. Background technique [0002] Pumped storage power plants are flexible and reliable in operation, fast in working conditions, and low in environmental pressure. They are a relatively economical energy storage method, and can be used for peak shaving and valley filling, phase modulation, and smooth output power of renewable energy. Configuring pumped storage with a certain installed capacity in the power system is an important choice to solve the impact of the current large-scale development of new energy on the security and stability of the power grid. [0003] Compared with fixed-speed pumped storage units, variable-speed pumped-storage units have the advantages of providing automatic system control capacity, adaptin...
