基于FDR的相间短路故障快速自动诊断与隔离的研究

摘要

以管理济宁城区整个配电网工程为例,介绍了FDR4011-GSM配电自动化故障检测装置的结构、主要参数、功能及实际应用,详细分析了该装置处理放射状线路和环网状线路两种相间短路故障的原理.分析结果表明,该装置可实现相间短路故障的快速自动诊断与隔离,具有较好的可操作性、实时性和稳定性.%Taking project of managing distribution network of Jining, the paper introduced structure,main parameters, functions and actual application of FDR4011-GSM fault detection device of distribution automation, and analyzed principle that the device processes two interphase short circuit faults of radial line and ring network line in details.The analysis result showed that the device can realize rapid and automatic diagnosis and isolation of interphase short circuit fault and has good operability, real-time performance and reliability.
