投退高压电抗器对系统电压产生的影响

在电网中，高压并联电抗器的主要作用是大量补偿线路充电无功，起平衡系统无功潮流分布、改善功率因数和调压的作用。借助PUM装置的高精度同步采集和动态过程记录功能，对宁夏电网第一次对高压并联电抗器投退的动态全过程进行测试分析。全面了解和掌握330kV安固线加装高抗后投退时对宁安变330kV母线电压的影响，并对330kV安固线上安装60Mvar高压并联电抗器的补偿度问题进行了计算验证。

Discussion on the impact of the high voltage reactor joining in and dropping out the service on the system voltage

Based on the high accuracy synchrounous collection and dynamic process record function of PUM device, makes the test analysis on the whole process of the high voltage shunt reactor joining in and dropping out of service for the first time in Ningxia Power Grid, finds the impact of the high voltage shunt reactor joining in and dropping out of service on 330 kV bus voltage after installed high voltage reactor in Ningan Substation of 330 kV power line, and calculates and validates the compensation degree of 60 Mvar high voltage shunt reactor installed on 330 kV power line.
