20kV孤网电压整体偏高治理分析

Governance analysis for voltage high of the overall 20 kV isolated Grid

分析了独龙江20 kV电网电压偏高的原因,分别对配变调档、加装电抗器、发电机进相运行三种解决方法进行了潮流分析计算,通过综合比较,提出了利用水电站单机或多机进相运行的解决方案,实际运行表明,所提出的解决方案较好的解决了电压偏高问题,具有较好的实用价值。

Country 20 kV power grid are analyzed in this paper the reason of higher voltage, respectively to change shifting gear, mounted to the reactor and generator leading phase operation, three kinds of solution for the trend analysis and calculation, through comprehensive comparison, the proposed use of hemp will be hydropower station operation with single or multiple machine into the solution of practical operation show that the proposed solution to better solve the problem of high voltage, has good practical value.
