A method and device for relay protection and control logic fault location

Abstract

The invention discloses a relay protection and control logic fault location method and device. The fault location method includes: responding to the acquired data of each node, judging whether a protection event in each node data has an action; Take the substation configuration data associated with the protection event in the preset logical relationship library, and dynamically create a logic analysis data table associated with the protection event that has occurred; based on the substation configuration data, fill the logic analysis data table in real time; respond In order to obtain the instruction to complete the filling, it is judged whether there is a missing item in the logical analysis data table. If there is a missing item in the logical analysis data table, the fault location is performed based on the association relationship of the configuration data that has not been filled. According to the association relationship of the missing configuration data, the cause of the logical fault can be quickly found out, thereby realizing the automatic fault identification of the protection and control logic.

Description

technical field [0001] The invention belongs to the technical field of electric power automation, and in particular relates to a relay protection and control logic fault location method and device. Background technique [0002] With the large-scale operation of smart substations in recent years, its proportion in the entire power grid system is also increasing, which will also become a mainstream trend in the development of the future power grid system. In the smart substation, the digital communication transmission mode represented by Ethernet replaces the traditional hard-wired circuit. The main advantage of this mode is that all transmission signals can be exchanged and shared. Occupying a lot of communication and network technology, invisible in the transmission process and complicated troubleshooting, there is no corresponding rapid fault diagnosis and location method at present, which also makes the operation and maintenance of substations more difficult to control to ...
