Pumped storage power station comprehensive monitoring method

The invention discloses a comprehensive utility monitoring method for a pumped storage power station. The method comprises the following steps: acquiring a power generation plan of the pumped storage power station on that day and variable reservoir water volumes in an upper reservoir and a lower reservoir; in the peak period of the power load, the planned generating capacity in the power generation plan is read, and when the AGC adjustment range assessment value and the AGC adjustment rate assessment value are both qualified, the generator set is started; in the power load valley period, according to the valley period electricity price and the variable reservoir water amount in the upper reservoir and the lower reservoir, the valley period water pumping amount and the next-day power generation plan are planned; the operation data of the pumped storage power station and the power system are collected every 15 minutes every day, and the actual generating capacity, the operation data, the pumping capacity and th
