摘要
针对当前电力系统中电缆故障频发对供电可靠性和经济效益造成的严重影响,文章通过深入分析电缆接地故障的电气特性,结合高精度的信号处理技术,提出了基于电缆零序电流和电压波形分析的故障识别方法,能够有效区分电缆的持续性接地故障和间歇性接地故障,提高电力系统的故障检测效率和准确性,为电力电缆故障的快速诊断提供了理论依据和技术支持。
In view of the serious impact of frequent cable faults on power supply reliability and economic benefits in the current power system,this paper proposes a fault identification method based on cable zero-sequence current and voltage waveform analysis by deeply analyzing the electrical characteristics of cable grounding faults and combining high-precision signal processing technology.It can effectively distinguish the continuous grounding fault and intermittent grounding fault of the cable,improve the efficiency and accuracy of fault detection in the power system,and provide theoretical basis and technical support for the rapid diagnosis of power cable faults.
