Abstract

The invention discloses an intelligent linkage method and system for a fault wave recording device and a traveling wave ranging device, comprising: a fault recording device or a traveling wave ranging device or an integrated device for fault recording and traveling wave ranging in a substation Among them, after a certain device triggers the recording, it generates a linkage data packet, and sends the linkage data packet to the next device through the linkage data interface; the linkage data packet contains at least equipment type and startup type information; the next The device determines whether to trigger the linkage of the machine according to the device type and the start type information in the linkage data packet; at the same time, forwards the linkage data packet to another device through the linkage data interface. The invention can effectively avoid the problem of false start of all the devices in the linkage network caused by the disturbance of a certain device.

Description

technical field [0001] The invention relates to the technical field of electric power system relay protection, in particular to an intelligent linkage method and system for a fault wave recording device and a traveling wave ranging device. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In modern power systems, with the increasing network scale, fault recording and traveling wave ranging devices are being used more and more widely. The fault recording device and the traveling wave distance measuring device are responsible for monitoring the operation status of the power system, recording the real-time operation information of the system, and responsible for fault distance measurement, so as to correctly analyze the causes of accidents, study accident countermeasures, deal with accidents, and evaluate accidents for on-site technical staff. ...
