Simulation monitoring system and method for substation equipment in region

Abstract

The invention discloses a simulation monitoring system and method for substation equipment in a region. The system comprises an external signal assembly which is disposed at the substation equipment and has an identification number consistent with the substation equipment. The external signal assembly comprises a signal generator and a signal receiver which are respectively arranged at the substation equipment, and the external signal assembly is used for generating and receiving topological signals to calibrate a line topological structure formed by the position of the substation equipment. According to the invention, substation equipment with similar machine account parameters and working condition data is divided into the same monitoring cluster by adopting a hierarchical clustering algorithm, so the substation equipment of each monitoring cluster should have similar states; and the difference of the equipment in the cluster is known through mutual comparison of the operation data of the substation equipment in the same monitoring cluster, which substation equipment is in an abnormal state can be quickly judged, and anomaly detection accuracy is high.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a simulation monitoring system and method for substation equipment in an area. Background technique [0002] In unattended substations, based on the requirements of safety and timely response to unexpected events, it is necessary to configure necessary real-time automatic monitoring means to grasp the changing status of substation equipment and the operation status of substation equipment, improve the efficiency of substation inspection work, reduce Ineffective and inefficient labor volume. [0003] Prior art CN201810315632.5 discloses a monitoring method and device for a substation scene and equipment, including: obtaining the first image sequence data of the substation scene collected by the acquisition equipment; Constructing the simulated site map of the substation scene; obtaining the second image data of the substation equipment collected by the acquisiti...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a simulation monitoring system and method for substation equipment in the area, so as to solve the problem that in the prior art, only the substation equipment with a fault occurs can be identified only, and the rest of the substation equipment affected by the linkage of the substation equipment with the fault occurred is ignored. The scope of fault identification is limited, and it is difficult to fully control the faulty equipment, which affects the monitoring accuracy. In fault identification, the operating data is only analyzed based on manual experience such as thresholds, which makes the utilization rate of the data very low and buries the value of the data. , did not achieve the expected effect, and eventually led to the technical problem of low accuracy of fault discrimination
