磁控并联电抗器的应用研究

Application Study of Magnetic Controllable Shunt Reactor

为了限制过电压和补偿线路充电功率,需要在超高压交流输电线路装设高补偿度的并联可控电抗器。在推导了磁控并联电抗器(MCSR)模型的基础上,建立了超高压系统的仿真模型,且对动态无功补偿及限制甩负荷过电压进行了仿真。仿真结果表明,在线路传送功率发生较大变化时,MCSR能够实时动态补偿无功功率,使线路末端电压基本保持不变。

In order to restrict over-voltage and compensation line charging power,there is a need to install high compensation controllable shunt reactors in ultra high voltage（UHV） AC transmission lines.On the basis of derived model of magnetic controllable shunt reactors（MCSR）,simulation model of UHV system was established,and simulation for dynamic reactive compensation and restricting load shedding over-voltage was carried out.Simulation results show that when line transmission power takes great changes,MCSR can compensate real-time dynamic reactive power to keep lines end voltage stable.
