【摘要】 电力系统投切并联无功补偿装置时,容易产生过电压,造成电感元件的损坏,严重影响并补装置的安全运行。通过对10kV并补装置中电感元件的合闸与重燃过电压进行模拟计算,研究了采用并联电阻与间隙配合对电感元件进行过电压保护的效果。更多还原

【Abstract】 In power system,when parallel reactive power compensating devices are switched,overvoltage often occurs,which causes damage to inductors and operating problems to shunt capacitors.In this paper,the overvoltage occurred when shunt capacitors are removed or switched in a 10 kV power system are calculated,and the effectiveness of using shunt resistor and gap to mitigate overvoltage is studied.更多还原
