Intelligent auxiliary monitoring terminal of transformer substation

Abstract

The invention discloses an intelligent auxiliary monitoring terminal of a transformer substation, which comprises an intelligent terminal, wherein all monitoring equipment of the transformer substation is accessed into the intelligent terminal by an equipment adapter. The intelligent auxiliary monitoring terminal of the transformer substation is characterized in that the intelligent terminal is internally provided with a transformer substation intelligent terminal database and the service modules of equipment ADP (automatic data processing), state management, alarm management, task management, task executing management, exclusive management service, equipment management, service management, Master table management, log management and permission management. The transformer substation establishes the intelligent auxiliary monitoring terminal, and the seamless access and complete coverage of all online monitoring and auxiliary equipment monitoring systems of the whole station are achieved; by frequency conversion acquisition and data excavation, the intelligent acquisition of the auxiliary monitoring equipment is realized, and the data and the information of all monitoring equipment in the station are supplied to other high-grade applications.

Description

technical field [0001] The invention relates to an intelligent auxiliary monitoring terminal of a substation, which is used to unify and integrate auxiliary equipment monitoring and online monitoring systems in a substation, and provide data services and application services, and belongs to the field of intelligent substations of electric power systems. Background technique [0002] The development of smart grid requires accelerating the research and promotion of smart substations in the substation link, and promoting the informatization and intelligence of all station equipment. With the application and promotion of unattended substations, and the trend of continuous deepening development, the centralized monitoring of various equipment in substations has become more and more important. Now the monitoring situation of substations is as follows: [0003] 1) The online monitoring of equipment is basically developed and established by the original monitoring device manufacture...

AI Technical Summary

Problems solved by technology

Each system works independently, equipment channels, servers, network channels and computer resources are repeatedly configured, and resources are wasted

[0004] 2) Only part of the important alarm information and the general alarm information are uploaded to the integrated automation system for public equipment monitoring, and most of the data has not been transmitted remotely. After receiving the alarm information, people must be sent to the site to check the specific information, which is costly and inefficient , The processing time is long, so that the effectiveness of the monitoring system cannot be fully utilized

[0005] 3) It is difficult to maintain the existing monitoring system

On-site and decentralized maintenance of each monitoring system requires a large workload, which is not conducive to comprehensive monitoring of various equipment or even similar equipment, and is also not conducive to unified maintenance and management

[0006] 4) At present, there are already some online monitoring equipment in the substation. With the development requirements, a large number of online monitoring equipment need to be added or updated

There is no unified specification and requirement to restrict monitoring equipment, let alone a unified system for management

[0007] 5) The communication interfaces and communication protocols used by various online monitoring and auxiliary equipment monitoring devices are various, and the monitoring content and indicators are not standardized and uniform
