摘　　要：随着智能电网技术的发展和大量精密用电设备的使用,对供电的电能质量和可靠性提出了更高的要求。大量冲击性负荷的频繁波动,导致电网负载侧功率因数偏低,电压波动较大,为了改善这一现象,介绍了TCR+FC型静止无功补偿器(SVC)的工作原理,应用PSCAD/EMTDC软件针对TCR+FC型SVC建立负荷补偿的系统和控制模型,分别以改善功率因数和提高母线电压为系统目标进行了仿真分析,并得出仿真波形和数据。仿真结果表明所用控制方法可行,可以指导SVC控制器的硬件设计。with the development of the SmartGrid and precision electrical equipments are widely used,the power quality and reliability are put forward higher request.The frequent fluctuations of large impact load,lead to electric load side power factor is low, voltage fluctuation bigger,in order to improve this phenomenon.This paper introduces the working principle of TCR＋FC type static reactive power compensation,use the PSCAD/EMTDC software to build the system and control model of load according to TCR＋FC type SVC,to improve the power factor and improve the bus voltage as the system target for simulation analysis,and the simulation waveform and the data.The results of simulation show that the control method is feasible,and can guide the hardware design of the SVC controller.
