Intelligent alarm and fault diagnosis system for transformer substation and scheduling center

Abstract

The invention discloses an intelligent alarm and fault diagnosis system for a transformer substation and a scheduling center. According to the system, an alarm is electrically connected with a transformer substation alarm information integrated function module; the transformer substation alarm information integrated function module is electrically connected with a transformer substation alarm information processing function module; the transformer alarm information processing function module is electrically connected with a scheduling center-transformer substation information interaction function module; the scheduling center-transformer substation information interaction function module is electrically connected with a scheduling center alarm information splicing function module; and the scheduling center alarm information splicing function module is electrically connected with a scheduling center intelligent alarm function module. Due to the adoption of the intelligent alarm and fault diagnosis system, the situations that the coordination between centralized diagnosis of the scheduling center and local diagnosis of the transformer substation adopted in a conventional fault diagnosis and intelligent alarm of the transformer substation and the scheduling center is lacked, the practicability of the centralized fault diagnosis function in not ideal, difficulty in rapidly analyzing and positioning exist, false alarm or miss of alarm information occurs, and the like are avoided.

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] Technical problem to be solved by the present invention: Provide an intelligent alarm and fault diagnosis system for substations and dispatching centers to solve the main problems of fault diagnosis and intelligent alarms for substations and dispatching centers It is the centralized diagnosis of the dispatching center and the local diagnosis of the substation. There is a lack of coordination between the two. The practicability of the centralized fault diagnosis function is not ideal. It is very difficult to quickly analyze and locate the fault, and the alarm information may be misreported or missing, etc. It is often impossible to determine the real cause of the alarm and other issues
