Abstract: Introduction was made to the problems of network topology, telesignalisation and measuration. The problem of measuration included 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.
Key words: state estimation; energy management system (EMS); power application software (PAS); automatic voltage control (AVC)
