中文摘要: 采用时域法分析了串联谐振的发展过程,研究了中性点电压的变化特点,发现串联谐振时中性点电压的发展过程与单相接地故障消失后的情形完全不同.通过辨识单相接地故障与串联谐振,提出了一种消弧线圈有效退出的控制策略,并通过理论分析和仿真实验证实了该方法的可行性和有效性.

Abstract:With a time-domain method,the mechanism of the SR is analyzed and the recovery process of the neutral voltage is studied. It is found that the neutral recovery voltage is significantly different from that in the SPG fault. Accordingly,a quit strategy about the ASC is proposed by the identification of SPG faults and SR. Finally,simulations,as well as theoretical analyses,illustrate the feasibility and validity of this method.
