Multi-data source-based intelligent inspection system of substation and integral diagnostic method

Abstract

The invention discloses a multi-data source-based intelligent inspection system of a substation and an integral diagnostic method. The intelligent inspection system comprises primary equipment intelligent inspection system, secondary equipment intelligent inspection system and an in-station on-line monitoring data source, wherein the in-station on-line monitoring data source is connected with an integral business data platform through an in-station network safety communication transmission system. By the intelligent inspection system, the technical problems that existing manual inspection cannot be completely substituted by the prior art, the target is not achieved by an existing inspection system, the existing inspection system is only used as an auxiliary inspection means, manual participation is still needed, the existing inspection system is abnormal in inspection result and unilateral in diagnostic method, a monitoring system is only used for displaying data, no effective combined integral judgment with inspection result data is performed, a circuit breaker in the existing inspection system is affected by severe weather during video operation and monitoring, the closing and breaking state of the circuit breaker cannot be accurately identified by visible light shooting, and interference is brought to a background operator even false operation is caused are solved.

Description

technical field [0001] The invention belongs to the substation intelligent inspection technology, in particular to a substation intelligent inspection system and comprehensive diagnosis method based on multiple data sources. Background technique [0002] With the progress of society, it has become an inevitable trend for the power system worldwide to develop towards large-scale interconnection. The entire power system has realized network interconnection, but the safe and stable operation of the system is facing huge challenges, which can be said to affect the whole body. For the entire large power grid, a certain equipment in a substation is small, like a drop in the ocean, but it plays a pivotal role. Major accidents are often caused by failure to detect or deal with small accidents in time, leading to chain reactions. Rapid expansion, leading to collapse of the large-scale ionization system. Electric energy plays a vital role in the national economy and people's daily l...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is to provide an intelligent substation inspection system and a comprehensive diagnosis method based on multiple data sources, so as to solve the problems of incomplete inspection objects and insufficient inspection methods in the inspection system existing in the prior art. It cannot completely replace the existing manual inspection; none of the existing inspection systems has achieved this goal, and can only be used as an auxiliary inspection method, which still requires manual participation; the abnormal diagnosis method of the inspection results in the existing inspection system is one-sided

All inspection systems only give inspection results through the direct data of the inspection terminal; the monitoring system is only used for data display, and has not been effectively combined with the inspection result data to make comprehensive judgments; the existing inspection system has a circuit breaker During video operation monitoring, affected by bad weather, visible light photography cannot accurately identify the closing and opening status of the circuit breaker, causing interference to background operators, and even causing technical problems such as misoperation
