摘要
电容器组的正常投切是保证交直流电网系统稳定运行的重要因素,通过调度能量管理系统中SOE信息对电容器组开关动作次数进行统计和分析,将单条母线下同容量的电容器投切次数进行对比,对投切次数较多的进行预警,实现对电容器投切次数的实时监测,助力电压无功补偿的优化,提高电容器设备的运行管理水平。
The normal switching of capacitor bank is an important factor to ensure the stable operation of AC/DC power grid system.In this paper,the SOE in the supervisory control and data acquisition is used for statistics and secondary analysis of data on the switching times of capacitor banks.The switching times of capacitors with the same capacity under a single bus are compared,and the early warning for those with more switching times are given.This method realizes the real-time monitoring of the number of capacitor switching times,helps the optimization of voltage reactive power compensation,and improves the operation and management level of capacitor equipment.
