摘要
随着高压电网无功补偿需求的增大,无功补偿电容设备大量增加。合理配置电容器保护和确定电容器保护整定值十分重要。提出了高压并联电容器组专用保护方式并探讨了保护整定值设定方式。该专用保护方式可实现单台电容器电容量、电容器(串段)电压(差)的监测,可以自由设定电容器保护定值,并将放电线圈纳入保护区内。
With the increasing demand of high voltage power grid reactive power compensation,reactive power compensation capacitor equipment has greatly increased.Reasonable capacitor protection configuration and capacitor protection setting value is very important.This paper put forwards the special protection of high voltage shunt capacitor bank and setting method for protection setting value.The special protection can monitor a single capacitor capacitance,capacitors voltage or capacitor strings voltage difference.Special protection can be freely set capacitor protection fixed value.Special protection can realize discharging coil into the protected area.
