摘　　要：电弧炉是非常典型的非线性负载,对电网电能质量影响严重。针对江苏永钢集团110 t电弧炉的电能质量问题,设计了角接式STATCOM+FC的综合补偿装置,实现了无功补偿、负序电流补偿和谐波补偿为一体的综合补偿功能。现场运行结果表明,不仅全面解决电弧炉电能质量问题,同时给企业节能降耗,具有很好的发展前景。Electric arc furnace（EAF） is typical nonlinear loads in the power supply system, which has serious influence on power quality of power grid. Aimed at power quality problems of 110 tons EAF in Jiangsu Yonggang Group, the comprehensive compensation device of delt-connected type STATCOM＋FC is designed, and the reactive power compensation, negative sequence current compensation and harmonic compensation for the integrated compensation function is realized. The field operation results show that the electric energy quality of EAF is not only fully resolved, but also energy saving for the enterprise,which has a very good development prospect.
