Dynamic characteristics of pumped storage unit based on the full-size converter

For enhancing the regulation performance and efficient operation of pumped storage power plant, this paper proposed to combine a hydro-generator set with full-size converter achieve decoupling control machine grid. On basis model test, characteristics certain pump-turbine had been discussed implication for was highlighted. At same time, modeling side were presented, simulation results showed that hydroelectric generator system based on could track torque change properly through variable-speed due from fixed grid frequency. The analysis revealed it is possible operate plant beneficially by adopting between motor improve dynamic effectively.
