摘　　要：基于电力系统综合程序对果洛联网工程过渡阶段110 kV输变电工程带电试运行期间可能存在的工频过电压风险进行仿真分析,阐述充电过程中果洛电网110 kV母线电压上升情况及主变压器配置低压电容器、电抗器对电压调节灵敏度,制定方法及合理预控方案,保证果洛电网安全稳定运行。Based on electrical power system comprehensive program, the simulation analysis on the risk of power frequency over voltage in the 110 kV power transmission and transformation project during the trial operation in the transition of the GUOLUO grid interconnection project is made, the voltage rising in the 110 kV GUOLUO power grid and the sensitivity of the low voltage capacitor and reactor equipped for the main power transformer to the vohage regulation are analyzed. And in end the preventive control method and scheme are also given to ensure the steady operation of the GUOLUO power grid.
