Abstract: This paper studies the Qingyuan pumped-storage power station multi units safety control strategy during load rejection at the same time, through the comparative analysis of several schemes, design the transmission line trip trigger generator tripping logic, optimize the existing protection system control strategy, the formation of the single line power station a few units safety control strategy during load rejection at the same time, the realization of multiple units in the case of lines correctly load rejection, ensure the safety of unit operation.
