I. Overview

The intelligent substation auxiliary monitoring system is an important component of the smart substation and is an integrated information platform integrating automation technology, computer technology, network communication technology, video compression technology, radio frequency identification technology, and intelligent control technology. The integration, optimization, management, and control of various auxiliary production systems in substations have become an indispensable and important technical means for the implementation of a “big operation” strategic system. The platform is equipped with temperature and humidity sensors, flood detectors, infrared sensors and other instruments. It is connected to the network and uses video surveillance, security guard alarms, access control monitoring, environmental monitoring, lighting control, and fire alarm systems to form workstations, and sensors and controls. The devices, devices and people are connected, with intelligent identification, lighting control, remote monitoring, environmental monitoring and other functions.

Second, the purpose

By standardizing and integrating the existing isolated and scattered secondary system resources, the optimized configuration of the secondary system, the sharing of information resources, and the seamless connection between the departments can be realized, thereby improving the integrated operation level of the grid and solving the secondary system types. Problems such as cumbersome operations and fragmented operation information meet the needs of the construction of a large-scale operation system.

1. By standardizing the information transmission methods and communication protocols of various auxiliary production systems, it is conducive to unified management and facilitates the expansion of new intelligent functions.

2. It can realize the management requirements of substations “data integration, business collaboration, management centralization, and resource sharing”, realize centralized information collection, centralized transmission, centralized analysis, centralized application, and realize the interactive application with other systems, and fundamentally eliminate the generation of "Information island" situation.

3. Through the organic integration of various auxiliary production systems, not only can the performance of each subsystem be improved, the unified management of system functions and extensive linkages can be realized, and the emergency handling and response capability can be improved, and the prevention and management of accidental accidents and emergencies can be strengthened. ability. In order to fully enhance the system's intelligent management.

4, through a variety of auxiliary production systems, high integration, unified upload, is conducive to the overall control of the situation within the station, to strengthen the operation and management of substations, improve the quality of supervision of substation auxiliary production systems, reduce maintenance costs, improve transport Dimensional efficiency.

Third, the scope of application

Can be widely used in various voltage level substations/stations, converter stations, opening and closing stations / etc.
