摘要

针对某金属硅厂矿热炉短网布置、炉体和炉料等不平衡导致三相负荷电流不平衡

严重危及了当地110 kV变电站的正常运行

提出使用TCT型SVC装置对矿热炉进行分相功率补偿

治理三相电流不平衡的方法

并通过PSCAD仿真试验验证了该方法的可行性和高效性。

Abstract

As for normal operation of 110 kV substation which is in serious danger due to unbalance of three-phase load current caused by short network configuration of certain silicon metal mines arc furnace and unbalance of furnace body charge

a method on using thyristor controlled transformer（referred to TCT）type static var compensator（referred to SVC）to perform phase power compensation of the arc furnace and control unbalance of three-phase current is raised. Both feasibility and high efficiency of the method is verified by PSCAD simulation test.
