Abstract

The invention relates to an online fault diagnosis method for a substation telecontrol device, which includes an interval layer equipment, a telecontrol device, a control system, and an online fault diagnosis system for a substation telecontrol device; it is characterized in that: the interval layer equipment and the control system are Communication with the telecontrol device, the online fault diagnosis system of the substation telecontrol device obtains the communication information between the control system and the telecontrol device, the telecontrol device and the bay layer equipment through two mirror ports; the substation telecontrol device is online The fault diagnosis system is connected to the dispatching data network. The invention can diagnose the failure condition of the telecontrol channel on-line, and greatly improves the work efficiency.

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...
