A simulation monitoring system and method for substation equipment in a region

Abstract

The invention discloses a simulation monitoring system and method for substation equipment in a region, comprising: an external signal component, the external signal component is arranged at the substation equipment and has an identification number consistent with the substation equipment, and the external signal component includes respectively set In the signal generator and signal receiver at the substation equipment, the external signal component is used to generate and receive topology signals to calibrate the line topology formed by the location of the substation equipment. The present invention uses a hierarchical clustering algorithm to divide substation equipment with similar account parameters and working condition data into the same monitoring cluster. Based on this, each monitoring cluster substation equipment should have a similar state, and then through the same monitoring cluster. The mutual comparison of the operation data of the substation equipment understands the differences of the equipment in the cluster, and can quickly determine which substation equipment is in an abnormal state, and the accuracy of abnormal detection 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
