Abstract

A secondary operation and maintenance system relay protection device inspection tour method comprises the following steps of defining a relay protection device normal state expert database in a secondary operation and maintenance master station, and generating a standard value file according to the expert database; using the secondary operation and maintenance master station to configure an inspection tour strategy and generate an inspection tour strategy file according to the inspection tour demands; using the secondary operation and maintenance master station to issue the standard value file and the inspection tour strategy file to a secondary operation and maintenance substation; using the secondary operation and maintenance substation to carry out the inspection tour comparison on a relay protection device according to the standard value file and the inspection tour strategy file to thereby generate an inspection tour report file and return an inspection tour anomaly result to the secondary operation and maintenance master station; using the secondary operation and maintenance master station to call the inspection tour report file according to the inspection tour anomaly result. According to the relay protection device inspection tour method provided by the present invention, the inspection tour tasks are issued to the secondary operation and maintenance substation to execute, thereby being able to reduce the burdens of the secondary operation and maintenance main station, and improving the inspection tour effectively substantially.

Description

technical field [0001] The invention belongs to the technical field of relay protection operation and maintenance of power systems, and in particular relates to a method for inspecting relay protection devices in a secondary operation and maintenance system. Background technique [0002] With the promotion of unattended substations and the rapid growth of relay protection devices in substations, problems and difficulties in traditional protection inspections and regular inspections are gradually emerging, resulting in insufficient maintenance, excessive maintenance, early maintenance, maintenance lag, and blind maintenance. And other hidden dangers. The existing transmission and maintenance mode should gradually change to remote online diagnosis of actual operating conditions, and to carry out targeted inspections based on the health status of equipment. Under the premise of high maintenance costs, according to the unified data transmission specification, the panoramic info...
