摘要
本文结合载人航天发射场配电网监测系统配置情况,以图论为基础,根据配电网的拓扑结构,利用PLC实时监测的故障电流参数,提出了基于PLC监测信息的配电网在线故障诊断定位方法。该方法在配电网出现故障时能为载人航天发射场配电网故障分析与定位提供技术支持及决策依据。
This paper studies the monitoring system installed in manned spaceflight launch site distribution network, and puts forwaM a method of on-line fault diagnosis and location based on PLC monitor parameters, on the basis of graph theol7, the topology structurc of distribution network, as well as the real-time data of PLC on-line monitor of fault currrera paramelets when fauh ocears in, this method can provide technological support for fault analysis and location of distribution network, and suppors decision making of chief commander.
