Electrical equipment high-temperature early warning method, device and equipment and storage medium

Abstract

The invention discloses a high-temperature early warning method for electrical equipment. The method comprises steps of acquiring an environment temperature parameter, a humidity parameter, a currentparameter and a load parameter of target electrical equipment; then, calling a fitting optimization model set based on a least square method, and conducting fitting optimization of the obtained four parameters through a least square method to obtain a corresponding fitting environment temperature parameter, a fitting humidity parameter, a fitting current parameter and a fitting load parameter; andthen calling a BP neural network model to obtain an operation temperature parameter of the target electrical equipment according to the fitted and optimized parameters, and finally determining whether an alarm is needed according to the size of the operation temperature parameter. The method is advantaged in that influence of external factors on the parameters can be avoided through the least square method, the operation temperature parameter of the target electrical equipment can be obtained through the BP neural network model, and then alarming is carried out according to the operation temperature parameters. The invention further provides a device, equipment and a storage medium, which further have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a high temperature early warning method for electrical equipment, a high temperature early warning device for electrical equipment, a high temperature early warning equipment for electrical equipment, and a computer-readable storage medium. Background technique [0002] The safe and reliable operation of electrical equipment is directly related to the safe and reliable operation of the power grid, especially the ultra-large-scale transmission and distribution network. Especially at present, the power supply load of my country's power grid has been in a state of substantial growth, and the status monitoring of electrical equipment in operation will play a very important role. effect. In the power system, some contacts and joints of some equipment such as circuit breakers and generators are the main safety hazards related to the operation safety of the power grid. [0...
