Implementation method for remote measurement identification function of centralized monitoring transformer station

Abstract

An implementation method for the remote measurement identification function of a centralized monitoring transformer station comprises: a remote measurement identification module is arranged between a traditional market survey monitoring system and an instation monitoring system; and in an actual motion, the remote measurement bad data identification function of the remote measurement identification module is employed to filter the remote measurement data of a substation device in each transformer substation uploaded by the instation monitoring system, strain away obviously unreasonable false remote measurement data and emit alarm signals when dead remote measurement data occurs. Through adoption of the remote measurement identification module, the implementation method for the remote measurement identification function of the centralized monitoring transformer station can filter the remote measurement data of the substation device in each transformer substation in the power grid uploaded by the instation monitoring system and can avoid the influence of the bad data on the safe and reliable running of a dispatch automation system so as to realize the further optimization of the running and monitoring of the dispatch automation system, facilitate control and monitoring by operators, improve the whole network automation management level and ensure the safe, stable and high-quality running of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power system repair and maintenance, and in particular relates to a method for realizing the remote measurement identification function of a centralized monitoring substation. Background technique [0002] In the actual operation of the power system, the monitoring of telemetry data and whether it exceeds the limit will directly reflect whether the power grid can operate safely and stably. In addition, telemetry also provides decision-making basic information for dispatching automation systems such as voltage and reactive power automatic control systems. Therefore, telemetry data is very important information in power grid dispatching operation monitoring. [0003] figure 1 It is a schematic diagram of the operation monitoring method of the dispatching automation system commonly used at present; figure 1 As shown, in normal operation, the municipal dispatching monitoring system 1, that is, the dispatchi...

AI Technical Summary

Problems solved by technology

[0004] In the data collection link of the dispatching automation system, if there is interference in the transmission of the real-time telemetry data of the dispatching automation system or human errors or errors in data maintenance, the reliability of the dispatching automation system will be greatly reduced, and it will not be possible to send out-of-limit alarms, etc. question
