中文摘要以电弧炉负荷的综合补偿为背景,研究角接链式静止同步补偿器(static synchronous compensator,STATCOM)的环流控制方法。针对不对称电网电压下STATCOM补偿效果不理想的问题,从理论上分析电网电压负序分量与补偿偏差之间的关系。在此基础上提出一种基于网侧电流闭环的STATCOM环流控制方法,能够有效抵御不对称电网电压,消除负序电压造成的补偿偏差,同时保持较快的响应速度。RTDS混合仿真和现场运行试验,验证所提出的控制方法的有效性。; Focused on the compensation of electric arc furnace, researches have been done on the circulating current control of the delta-connected cascaded static synchronous compensator(STATCOM). According to the fact that the compensation effect of STATCOM becomes not so good under unbalanced grid voltage, theoretical analysis has been done to find out the relationship between negative sequence voltage and the compensating deviation. A new circulating current control method based on the feedback control of grid-side current is proposed, which can overcome the impact of the unbalanced grid voltage and keep rapid response at the same time. Hybrid simulation based on RTDS and field operating experiment verify the effectiveness of the presented control method.
