Pumped storage unit works in turbine-generator mode or pump-motor mode, Monitoring and Control system is very complicated, and each Pumped Storage Power Station's generating capacity and geographic conditions have their own characteristics. Therefore, it is very important to design a reasonable monitoring and Speed control system before the pumped storage station has been builded.
