Abstract

The invention discloses a method for implementing fault playback of a wave recording file in a relay protection device, which comprises the following steps of: importing data of the wave recording file of an electrical power system transient data interchange general format (COMTRADE) into the relay protection device through a general computer to perform the fault playback, converting the data of the wave recording file of the COMTRADE into the data capable of being identified by the relay protection device, and controlling the relay protection device to perform the fault playback. The method enables the relay protection device to perform the fault playback of the wave recording file of the COMTRADE without relying on the special test equipment so as to solve the problems of additional equipment required for the fault playback and inconvenient use.

Description

technical field [0001] The invention belongs to the technical field of power system automation devices, and realizes that in the power system relay protection device, the general format wave recording file for power system transient data exchange, that is, the COMTRADE wave recording file, can be directly played back for faults. A method for realizing fault playback of wave recording files in a protection device. Background technique [0002] COMTRADE is a common recording file format for power system transient data exchange defined by IEEE Std C37.111-1999, and is widely used in the field of power automation. When a fault protection action occurs in the system, the relay protection device or the dedicated fault recorder will record the changes of important electrical quantities in the system and the switching action in the COMTRADE format record file. Fault playback of fault recording files provides valuable information for analyzing the cause of system faults and checking...
