Filtration system and method of mis-telecommand scheduling end of transformer substation

Abstract

The invention discloses a filtration system of a mis-telecommand scheduling end of a transformer substation, which is connected with an supervisory control and data acquisition (SCADA) system and comprises a real-time data acquisition module, a telecommand processing center module, a telecommand display and confirmation module and a history management module, and an expert processing system comprises a signal analyzing and processing knowledge base, a signal analysis module and a human-computer interface. The invention also discloses a filtration method of the mis-telecommand scheduling end of the transformer substation, comprising the following steps: 1. the real-time data acquisition module collects power grid static information and real-time telemetering telecommand data information in the SCADA system; 2. when the expert processing system in telecommand processing center module analysis judges whether the real-time telemetering telecommand data information is a normal telecommand signal or a mis-telecommand signal; and 3. the telecommand display and confirmation module marks the signal which is judged to be in normal telecommand as a normal telecommand signal mark, marks the signal which is judged to be in mis-telecommand as a mis-telecommand signal and filters the mis-telecommand signal. The accuracy rate of the system signal and the power grid scheduling efficiency are improved by using the system and the method.

Description

Technical field [0001] The present invention relates to regional power grid monitoring, in particular to a filtering system for substation false remote signal dispatching end and a filtering method for substation false remote signal dispatching end. Background technique [0002] The SCADA system of the power dispatch center is a powerful tool for dispatchers to monitor the operation of the power grid and deal with accidents. With the continuous development of computer and network technology, the functions of SCADA systems are becoming more and more powerful. On the one hand, the application software based on the SCADA platform is becoming more abundant, such as voltage and reactive power automatic control, grid fault analysis and processing, etc. On the other hand, the demand for system integration and grid interconnection technology based on the IEC61970 standard is also increasing. Therefore, The external release and reception of real-time information (telemetry and remote sig...
