基于SOGI-PLL的高压电缆接地回路环流干扰抑制方法研究

Gaoya dianqi
回路电阻带电检测是高压电缆金属护层接地回路电气连接状态检测的一种新技术，该技术通过磁场耦合方式向高压电缆接地回路中注入异频激励，通过测量回路中的异频激励电压与电流响应信号的幅值与相位求解回路电阻，可有效发现回路中的进水受潮、螺栓松动、护层开裂等缺陷。电缆护层中工频环流的存在会对异频信号的注入产生影响，导致激励电源及耦合线圈工作异常，并且对异频信号的检测造成严重干扰，能否有效地抑制工频环流干扰是高压电缆接地回路电阻高精度检测的关键所在。为此，文中提出了一种基于二阶广义积分器锁相（second-order ...
