Analysis method based on smart power grid monitoring alarm information event

Abstract

The invention provides a monitoring alarm information event analysis method based on a smart power grid. Comprising monitoring signal events, intelligent diagnosis and analysis of accident tripping events, monitoring information event simulation, monitoring signal objectification based on natural semantic analysis, intelligent monitoring of event processes, setting of emphasized attention to various events provided by the system, and intelligent processing decision. Comprising the steps of constructing a typical information knowledge graph, constructing an alarm information basic knowledge query function and constructing an event analysis and disposal method.

Description

technical field [0001] The invention relates to the technical field of grid monitoring information dispatching methods, in particular to an analysis method based on smart grid monitoring and alarm information eventization. Background technique [0002] At present, the primary and secondary equipment alarm information of the power company and each substation of the power supply company is directly uploaded to the EMS system of the main station of the control center, which is displayed uniformly by the monitoring information alarm module of the EMS system. The monitors of the control center mainly monitor the operation status of all substation equipment through the EMS system , handle all kinds of faults and abnormal alarms that occur in the power grid. [0003] With the continuous improvement of the comprehensive automation level of substations and the continuous expansion of the power grid scale, the main station receives more and more primary and secondary equipment informa...

Problems solved by technology

[0005] At present, the monitoring and alarm information completely depends on the 7*24 hours of manual monitoring by the monitors, and it is difficult to complete the heavy monitoring tasks of massive signals with quality and quantity. It consumes a lot of time and energy, the handling efficiency of the monitor is low, and the work pressure is very huge

[0006] Untimely and inaccurate formulation of accident analysis, judgment and disposal methods increases the difficulty of accident handling, prolongs the time for accident disposal and restoration of power supply, resulting in loss of power supply, untimely detection of some equipment failures, defects, negligence or omissions, It is easy to cause equipment defects to be missed and not be dealt with in time, and eventually cause equipment failure, complete equipment damage or develop into a larger power grid accident due to delay, resulting in greater economic losses
