摘　　要：介绍了状态估计中网络拓扑及遥信与量测问题,量测问题包括遥测数据错误、人工伪量测置数、遥测数据封锁及遥测极性等。叙述了在调试新调度自动化系统时出现的一些状态估计典型故障的处理过程,为相关人员更好地维护状态估计提供了借鉴。Introduction was made to the problems of network topology, telesignalisation and measuration. The problem of measuration includ- ed errors in telemeasuring data, forged manual measuration data, telemeasuring data block and telemeasuring polarity etc. This paper expounded on the treating processes of some typical state estimation faults appearing at the time of debugging new dispatching automation systems, which provides references for the relevant personnel to maintain state estimation better.
