摘　　要：针对电弧炉负荷的电压波动、闪变与低功率因数等特性,分析了其工作原理。用PSCAD软件构造电弧炉模型、三相STATCOM及三单相STATCOM,并进行了仿真。分析了两种电路结构STATCOM对电弧炉负荷的治理效果。三单相STATCOM由于具有输出无功电流谐波含量低、响应速度快等优点而更加适合于电弧炉负荷的平衡化补偿。通过仿真验证了三单相STATCOM进行快速平衡化补偿的能力比较强。In this paper, according to the fuctuation and flicker, low power factor and other charateristics of electric arc furnace, the software PSCAD is used to structure the model of arc furnace and simulat it. The paper analized the principle of arc furnace, three-phase and single phase STATCOM, and separately construction three-phase and single phase STATCOM to control electric arc furnace. Due to the low harmonics in output reactive current and fast response characteristics, single phase STATCOM is suitable for balancing compensation of three phase unbalanced load. It was proved by the simulation results of the proposed compensation method that the single phase STATCOM possesses the ability to carry out fast balancing compensation.
