摘　　要：再起动是保障工艺流程安全的重要措施之一。通过对某石油化工装置变电所供电系统的运行工况分析,利用MVA法对电动机分批再起动进行了计算,并用ETAP进行仿真,根据MVA法计算结果和ETAP仿真结果,得出MVA法计算结果偏于保守的结论。Restart is one of the important measures to ensure the safety of process flow. Based on the analysis of the operation condition of the power supply system of a petrochemical plant substation, the batch restart of the motor is calculated by MVA method, and is simulated by ETAP. According to the results of MVA method and ETAP simulation, it is concluded that the results of MVA method are conservative.

关 键 词：MVA法 ETAP仿真 再起动 电压水平
