Abstract:

为了解决谐振接地系统中单相接地故障消弧和故障线路可靠识别的难题,本文提出一种基于新型磁控消弧线圈的电磁混合消弧及配合选线方法。采用由磁控电抗器(MCR)和逆变器构成的新型磁控消弧线圈,提出了基于接地故障电流无功和有功分量解耦补偿的电磁混合消弧及系统对地参数测量方法,详细分析了消弧线圈补偿对线路零序导纳的影响,提出了基于动态零序导纳的配合选线理论,利用逆变器的等效负阻特性,能够提高故障线路动态零序导纳对MCR调节量的灵敏度,论述了该方法及相应的配合选线控制策略和选线判据。该选线判据具有确定性和唯一性,无需集中交叉比较。通过仿真分析和模拟平台实验验证了本文所述理论、方法和控制策略的正确性和可行性。
