An Intelligent Alarm and Fault Diagnosis System for Substation and Dispatch Center

Abstract

The invention discloses an intelligent alarm and fault diagnosis system for a substation and a dispatching center, which comprises: the alarm is electrically connected with a substation alarm information integration function module; the substation alarm information integration function module is electrically connected with the substation alarm information processing function module; the substation alarm information The processing function module is electrically connected to the dispatch center-substation information interaction function module; the dispatch center-substation information interaction function module is electrically connected to the dispatch center alarm information splicing function module; the dispatch center alarm information splicing function module is electrically connected to the dispatch center intelligent alarm function module ;Solved that the fault diagnosis and intelligent alarm of the current substation and dispatching center are mainly two levels: the centralized diagnosis of the dispatching center and the local diagnosis of the substation. There is a lack of coordination between the two, and the practicability of the centralized fault diagnosis function is not ideal. Difficulty in positioning and alarm information may be falsely reported or missing.

Description

technical field [0001] The invention belongs to the technical field of power grid monitoring in the electric power industry, and in particular relates to an intelligent alarm and fault diagnosis system for a substation and a dispatching center. Background technique [0002] So far, the research on the two-level distributed intelligent early warning and fault diagnosis application system of substation and dispatching center is almost blank at home and abroad. At present, the research and application of fault diagnosis and intelligent alarm are mainly the centralized diagnosis of the dispatching center and the local diagnosis of the substation. However, there is a lack of coordination between the two, that is, there is a lack of distributed fault diagnosis and alarm functions coordinated by the substation-dispatching center. The substation fault diagnosis system is mainly used in the substation automation system, using the fault recording information in the substation Substati...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an intelligent alarm and fault diagnosis system for substations and dispatching centers, so as to solve the problem that fault diagnosis and intelligent alarming of substations and dispatching centers are mainly at the two levels of centralized diagnosis of dispatching centers and local diagnosis of substations. There is a lack of coordination between the two, and the practicability of the centralized fault diagnosis function is not ideal. It is very difficult to quickly analyze and locate faults, and the alarm information may be falsely reported or missing, and it is often impossible to determine the real cause of the alarm.
