摘    要：针对内蒙古通辽某铝厂6.3 kV配电网电能损耗严重、电能质量不高的情况,提出了利用TSC与APF并联应用的混合型SVC连续补偿大容量负载的无功和谐波分量。该装置于2007年投入使用后,取得了较好的补偿和滤波效果,达到了高可控性和快速响应性,对冶金行业供电系统无功补偿谐波治理具有借鉴意义。

Abstract: For 6.3 kV distribution grid of a certain aluminium plant in Tongliao,Inner Mongolia,electric energy loss is serious and power quality is poor.Therefore,a hybrid SVC based on TSC and APF was adopted to compensate reactive power and eliminate harmonics for high power load.The system was put into use in 2007,better compensation and filtering effect was obtained,and high controllability and fast response were achieved.For reactive compensation and harmonic control problem of power supply system in metallurgical industry,it can be used for reference.
