Abstract

The invention relates to a substation telecontrol device online fault diagnosis method, comprising spacer layer equipment, a telecontrol device, a regulate and control system and a substation telecontrol device online fault diagnosis system. The spacer layer equipment and the telecontrol device are in communication connection with the regulate and control system. The substation telecontrol deviceonline fault diagnosis system obtains communication information between the regulate and control system and the telecontrol device, and between the telecontrol device and the spacer layer equipment through two mirror ports. The substation telecontrol device online fault diagnosis system accesses a scheduling data network. According to the method, online diagnosis can be carried out on fault condition of a telecontrol channel, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an online fault diagnosis method for a substation telecontrol device. Background technique [0002] With the advancement of unattended, the remote control device of the substation is particularly important. Research on the monitoring and online fault diagnosis of telecontrol devices continues to deepen. At present, there is no tool for effective monitoring and auxiliary analysis of the upper-to-lower communication process of the substation telecontrol device. [0003] The fault diagnosis of existing substation telecontrol devices can only be divided into two types through manual judgment. [0004] (1) Manually log in the operating system of the telecontrol host to query the relevant process and data status for fault diagnosis. [0005] (2) Diagnose faults by adjusting the status of data packets received by the master station. [0006] The existing technology has the following dis...
