针对带静止变频器的抽水蓄能电动机变频起动初期运行的特殊性，运用“电压跟踪器法”以模拟电压代替实际电压实现对机端电压过零时刻的判定，仿真计算结果经与模拟实验和现场实测值比较，本仿真合理、可行，具有实用价值。
Aiming at the peculiarity of initial operation of pumped storage motor with static frequency converter, the method of “voltage tracker” is used to determine the voltage zero crossing time of terminal voltage with analog voltage instead of actual voltage. The simulation results are compared with simulation experiment and Field comparison, the simulation is reasonable, feasible, with practical value.
