摘要
针对传统的固定电容器组(fixed capacitor,FC)无功补偿设备存在过补偿或欠补偿,且易造成系统电压波动大的缺陷,根据磁阀式可控电抗器(magnetically controlled reactor,MCR)的无功补偿原理,设计了基于FC与MCR组合的动态无功补偿系统。对该无功补偿系统进行了仿真和样机试验,试验结果表明无功补偿系统能快速响应电力系统电压和无功功率的变化,在抑制电压波动和改善电能质量方面具有显著效果。将该无功补偿系统投运于110 kV变电站,运行效果表明能解决10 kV母线电压波动大和无功功率倒送的问题。
Aiming at problem of major fluctuation of system voltage caused for reasons of over compensation or deficiency of com- pensation of traditional fixed capacitor reactive power compensation equipment, a kind of dynamic reactive power compensation sys- tem based on Combination of FC and MCR was designed according to reactive power compensation principle of magnetic control re- actor. Simulation and prototype testing was conducted for this reactive power compensation system and results indicated that this system was able to rapidly respond to changes of power system voltage and reactive power as well as had obvious effects in constrai- ning voltage fluctuation and improving power quality. It was able to solve problems of major voltage fluctuation of 10 kV bus and re- active power send by input this reactive power compensation system in 110 kV substation.
