Abstract

The invention relates to a transformer substation signal alarm verification method and device. According to the substation signal alarm verification method, a test signal is sent according to the current signal state of a to-be-verified point, and the test signal state is opposite to the current signal state of the to-be-verified point. An alarm signal is generated according to the test signal. Whether the alarm signal is equal to a preset alarm signal or not is judged, and it is determined that the signal alarm function performance of a transformer substation is intact when the alarm signal is equal to the preset alarm signal. According to the transformer substation signal alarm verification method, the test signal opposite to the current signal state is sent, so that the displacement ofthe alarm signal can be obtained in time. The transformer substation signal alarm verification method can be used to replace manual work to perform alarm function verification so as to reduce the repeated work of the manual work and improve the accuracy and efficiency of the verification work.

Description

technical field [0001] The present application relates to the field of power equipment, in particular to a method and device for verifying a substation signal alarm. Background technique [0002] A substation based on an integrated automation system (hereinafter referred to as an integrated automatic substation) refers to a substation that applies modern electronic technology, communication technology and integrated microcomputer relay protection technology. Different from the manned substation, the comprehensive automatic substation can realize the remote operation and remote monitoring functions of all equipment. The signal alarm function of the comprehensive automatic substation is realized by the joint action of the comprehensive automatic system equipment, the signal secondary circuit and the signal source contact. The signal alarm function needs to be checked for the first time before it is put into operation, and then it needs to be checked regularly. [0003] At pr...
