Abstract

The invention relates to a maintenance method of an intelligent transformer station protective relaying device. The method comprises a self-maintenance process of the intelligent transformer station protective relaying device and a maintenance process of an external detection apparatus. The external maintenance process comprises arranging at least one detection interface on the intelligent protective relaying device and connecting the detection interface of the intelligent protective relaying device with a current simulation system through a cable. According to the invention, through arranging the detection interface on the intelligent protective relaying device and connecting the detection interface with the current simulation system, the state of the intelligent protective relaying device can be detected under the condition that the intelligent protective relaying device works normally.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to a maintenance method for a relay protection device of an intelligent substation. Background technique [0002] In recent years, with the rapid development of smart substations, the relay protection devices of smart substations are also facing a lot of maintenance work.
