摘　　要：针对江苏某钢厂交流电弧炉运行时给电网中其他用户带来的电能质量问题,提出了一套新型的TCR+FC型静止无功补偿装置(SVC)技术方案。根据对称分量法推导出了基于电压同步对称分量法的三相不平衡SVC无功补偿导纳实用算法。通过仿真软件CHP对该系统进行了仿真,结果表明该SVC装置能够有效治理由电弧炉引起的电能质量问题,并且补偿性能良好,具有较强的工程实用性。According to the power quality problems when AC - EAF in operation of a steel company in Jiangsu. A set of new TCR ＋ FC - type static var compensator （SVC） technology project is proposed. According to the asymmetric component method, the utility compensator admittance based on voltage synchronous symmetric component method of three phases imbalance was deduced. Through the simulation software CHP simulating the system. The results indicate that the SVC device can manage the power quality problems caused by static var compensator effectively, and has a good compensation performance. And it has a good engineering application effect.
