Abstract

In this paper, the characteristics of power oscillation of pumped storage synchronous motor under pumped condition are studied, and the causes of misoperation of conventional low power protection are analyzed. Based on digital simulation and actual data analysis, a multi-stage low power protection is proposed. The power setting value of each section matches the delay setting value, which can adapt to the characteristics of motor power oscillation and effectively solve the misoperation problem of conventional low power protection. The simulation results show that its performance is stable and reliable, and the problem of misoperation of conventional low power protection is solved.
