摘要
提出了由具有同步测量功能的故障指示器、就地信息合并控制单元以及配电自动化系统构成的信息集成方案。该方案将广域测量与控制技术应用于配电网络。介绍了新型故障指示器的功能特征、程序流程。说明了就地信息合并控制单元的功能特征以及其与故障指示器之间的通信方式。提出了利用故障指示器与就地信息合并控制单元进行相间短路故障、励磁涌流、负荷冲击、重合闸、线路断线、退出运行等馈线运行状态的常规监测功能的改进方案。提出了通过就地信息合并控制单元利用暂态电气量进行单相故障方向判别的故障区段定位新方法。研究结果表明,该信息集成方案能实现就地的故障及异常运行状态的诊断,可明显提升配电自动化系统的数据就地分析处理及信息交互能力。
An information integrated scheme consisting of the fault circuit indicator（FCI）with synchronization measurement function,local information merge and control unit（LIMCU）and distribution automation system（DAS）is proposed.The wide area measurement and control technology is applied in the distribution network.The functional characteristics and program flow chart of the novel FCI are described.The functional characteristics of LIMCU and the communication style between LIMCU and FCI are briefly treated.Conventional monitoring function improved methods using FCI and LIMCU are proposed. New diagnosing methods involve phase to phase short circuit,inrush current,shock loading,automatic reclosing,openconductor, transmission line standby.The new methods of locating single phase to ground fault section through the LIMCU to analyze the transient electric information and estimate the fault direction is also proposed.The research results show that the information integrated scheme can realize local diagnosis of fault and the abnormal operation states of the distribution network. The scheme can appreciably enhance the local data processing ability and information interaction ability of the distribution automation system.
