Intelligent substation warning and aid decision making system

Abstract

The invention discloses an intelligent substation warning and aid decision making system for processing potential safety hazards or faults in a substation according to the expert knowledge base technology. The intelligent substation warning and aid decision making system comprises a center control computer and an intelligent substation monitoring system, and the center control computer is further provided with an expert knowledge base module, an expert knowledge explaining module, a warning and decision inference machine module and a system data warehouse module. By means of the system, the essence of faults is found out from the aspect of ways of thinking of experts, and expert knowledge is used for forming solving plans for assisting fault processing personnel in dealing with the faults. Through warning message layered optimization, comprehensive induction, fault inference model establishing and accident inversion, the intelligent substation warning and aid decision making system can be effectively used for guiding and helping operating personnel to make correct judgment about accidents or abnormities quickly; meanwhile, all kinds of data and operation states of the substation are analyzed and processed in real time so that potential safety hazards of the system can be found, corresponding warning messages can be generated automatically, and the operation management level and power supply reliability of the substation are improved.

Description

technical field [0001] The invention relates to a substation automation control early warning system, in particular to an intelligent alarm and auxiliary decision-making system capable of timely processing hidden dangers or faults. Background technique [0002] With the rapid development of social economy, the demand for electricity in various industries is increasing, and the requirements of power users for the reliability of power supply of the power grid are also getting higher and higher. [0003] At present, the processing of alarm information in the substation automation control system, including SOE information, remote signal displacement information, protection event information, telemetry limit information, system information, etc., only performs simple grading and classification processing. When an accident occurs in a substation , the operator on duty is caught in the vast amount of alarm / accident information, and cannot quickly judge the cause of the accident. Us...

Problems solved by technology

[0003] At present, the processing of alarm information in the substation automation control system, including SOE information, remote signal displacement information, protection event information, telemetry limit information, system information, etc., only performs simple grading and classification processing. When an accident occurs in a substation , the operator on duty is caught in the vast amount of alarm / accident information, and cannot quickly judge the cause of the accident. Usually, it is mainly based on the experience of the fault handling personnel and some processing procedures, which may lead to incomplete fault handling plans and incomplete fault handling. , when it is serious, it is easy to expand the fault and cause a larger accident
