并联电容器组保护原理及整定原则

Protection Fundamental and Setting Principle of Shunt Capacitor Bank

随着高压配电网无功补偿需要的加大,无功补偿电容设备大量增加,合理配置及整定并联电容器组保护显得尤为重要。本文对并联电容器组保护原理和整定原则进行较详细的介绍,尤其是对电容器组中多台电容器故障的保护进行较深入的分析,对正确配置电容器组保护和电容器组各种保护的整定计算十分有益。

With the increasing need of reactive power compensation in the high voltage distribution network and the increasing capacity of reactive-load compensation equipments,it becomes more important to configure and set the protection of shunt capacitor bank optimally.The protection fundamental and setting principle of shunt capacitor bank,especially,analyzing of protection for multiple capacitor fault are discussed in this text.It is helpful to correctly configure and set the protection of shunt capacitor bank.
