摘要
结合实际运行的变电站,对其中的无功补偿电容器合闸过电压、涌流进行了理论计算,并利用ATP-EMTP软件,对无功补偿电容器合闸过程中的电压、电流的暂态过程进行仿真。从两方面印证无功补偿电容器合闸过电压、涌流的幅值、持续时间及规律,为电容器保护定值的选择提供科学的依据。
This paper makes a theoretical calculation on the overvoltage and surge current at switch-on of capacitors for reactive power compensation and simulates the transient voltage and current at switch-on of capacitors for reactive power compensation by using ATP-EMTP software.It confirms from two way the amplitude,duration and rule about overvoltage and surge current at the switch-on of capacitors for reactive power compensation that provide a scientific basis for choosing the setting of protection on the capacitors.
