Abstract

The invention discloses a real-time monitoring method and system for the safe operation state of power grid equipment. The method comprises the following steps: training an equipment evaluation modelbased on historical equipment operation data; calculating relative evaluation between the devices based on the device operation data and the device evaluation model; and pushing an evaluation result of the relative safe operation state of the equipment. According to the invention, a real-time evaluation system of the power grid equipment is formed by constructing multi-stage evaluation indexes, sothat the defect of low timeliness of operation and maintenance state evaluation is overcome; on the basis of historical experience of power grid monitoring personnel, the SVM algorithm is adopted andthe real-time evaluation model is constructed, so that the labor amount of the monitoring personnel for manually judging risk equipment is reduced, the reliability of an evaluation result is improved, and the safe operation level of a power grid is improved.

Description

technical field [0001] The invention belongs to the technical field of monitoring the safety status of power grid equipment, and relates to the real-time evaluation of various primary equipment, secondary equipment and auxiliary equipment in substations, power transmission channels and power supply area equipment, and in particular to a real-time monitoring of the safe operation status of power grid equipment. Monitoring method and system. Background technique [0002] With the gradual advancement of the smart grid construction and the gradual expansion of the grid scale, the monitors need to monitor more and more grid equipment, and the monitoring method that relies entirely on manual judgment of equipment safety operation level is becoming increasingly unsuitable for the current grid construction. To ensure the safe operation of the power grid, it is necessary to evaluate the equipment status in real time, confirm the equipment with high operation risk, and facilitate the ...
