Unattended power station environment monitoring system
At present, many auxiliary substations such as video surveillance, environmental monitoring, safety precautions, fire alarms, and access control systems are mostly independently operated. Data is uploaded through different channels, and even each system is equipped with independent management personnel. The integrated monitoring and centralized management of the system has virtually reduced the integration and availability of the system and increased the management costs of the system. Through the application of the unattended power station environment monitoring system, the potential of the existing system will be excavated to the maximum, the cost will be saved, and the system efficiency will be improved.
The unattended power station environment monitoring system is an important part 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. It is specially used to realize the integration, optimization, management and control of various auxiliary production systems of substations, and has become an indispensable and important technical means for implementing the “large operation†strategic system.
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 sharingâ€, 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.
