摘要
提出了一种基于脉冲信号注入法的故障定位方法。该方法不受系统运行方式、拓扑结构、中性点接地方式以及故障随机因素等影响,且信号注入地点选择灵活、脉冲宽度、周期可调。文章给出了脉冲信号源的软、硬件设计方案,采用C8051F310单片机实现高压脉冲信号发生器,并基于电磁感应原理设计了信号探测器。
One method of fault location based on pulse signal injection has been promoted in this paper,which is not only independent of the following factors,such as system operating mode,topology,neutral grounding and random fault,but also the site of signal injection,the width and period of pulse are flexible and adjustable.In this paper the design scheme of software and hardware for signal source is proposed,high-pressure pulse generator is carried out by adopting C8051F310 MCU,and signal detector is designed base...
