Abstract

According to the substation automation equipment state diagnosis method and system based on the digital mirror image, available state parameters in intelligent substation automation equipment are analyzed, the operation condition of the substation automation equipment is collected, analyzed and processed in real time through an intelligent operation and maintenance gateway machine, and key information capable of representing the operation state of secondary equipment is extracted; a data communication transmission protocol is adopted to upload the panoramic working condition information of the automation equipment to a remote master station, and a digital mirror image is formed based on the whole-process operation working condition and equipment parameters of the automation equipment in combination with automation historical operation data; according to the method for evaluating the state of the equipment and verifying the influence of key influence factors on the state of the automatic equipment by using the digital mirror image, the state of the automatic equipment is evaluated and optimized according to the evaluation and prediction result of the state of the digital mirror image and the analysis of the real-time state; the method can effectively solve the problem of state perception and evaluation of automation equipment and support business functions thereof, and improves the reliability level of power grid automation business.

Description

technical field [0001] The invention belongs to the technical field of state monitoring of electric power automation equipment, and in particular relates to a method and system for state diagnosis of substation automation equipment based on digital mirroring. Background technique [0002] For smart substations, automatic equipment operation status diagnosis is the basis for ensuring safe and economical operation of the power grid and carrying out condition-based maintenance. The core is to establish a reasonable equipment status diagnosis model. Based on the status diagnosis results of automation equipment, a series of maintenance strategies for automation equipment can be formulated to meet the actual situation, and finally achieve the goal of safe and economical operation of the power grid, which can not only save a lot of equipment maintenance costs and resources, but also effectively improve the reliability of equipment operation. nature, reflecting a great economic adva...
