Design thinking
With the advancement of power generation technology and the support of the development of information technology, it is moving from digital control and information management to a higher-performance automatic, reliable, intelligent and efficient direction.
In order to thoroughly implement the national policy of in-depth integration of industrialization and industrialization, and actively realize the strategic deployment of the Made in China 2025 plan, the comprehensive security system of xxx power plant will be supported by modern information technology, and fully learn from advanced concepts and management methods such as "Industry 4.0" and "Industrial Internet". Based on the status quo of auxiliary system construction, aiming at realizing the standardization, integration and intelligent features of auxiliary systems, and supported by advanced and applicable technologies to meet the management needs of smart power plants, it helps power plants achieve energy saving, consumption reduction and reduction. To meet the policy requirements of emission reduction, realize the intensive and efficient management needs of the power generation group, and gradually complete the transformation and construction of new digital power plants and smart power plants.
Design Principles
With the continuous advancement of science and technology, various new technologies continue to emerge. The comprehensive security system of xxx power plant is a comprehensive monitoring and management system that integrates network communication technology, security technology and software engineering technology. The construction of the system will follow advanced technology, complete functions, Based on the principles of stable performance and cost saving, the system strives to make the system a comprehensive monitoring and management platform for the practical application of smart thermal power plants, and comprehensively considers maintenance and operation factors, and will leave room for expansion for future development, expansion, transformation and other factors. When designing the system, we pursue "five unifications", and strive to find the best combination and entry point of unification:
1) The unity of practicality and economy
Adhere to the principle of practicality first. The system should be able to meet the various monitoring business requirements of the thermal power plant system to the greatest extent, meet the business needs of system managers and users, and be able to adapt to the development of new technologies. At the same time, efforts should be made to reduce construction costs. high product.
2) The unification of rationality and advancement
The design of the system scheme strictly follows the design criteria of systems engineering, and strikes a balance between the rationality of the system and the advancement of technology. Efforts should be made to pursue the scientific rationality of the function of the entire system, and to prevent one-sided pursuit of high indicators and advanced nature of a certain part. On the premise of ensuring the function and performance of the entire system, mature, inheritable and advanced technologies with broad development prospects are adopted to the maximum extent.
3) Unification of standardization and openness
The system design adopts standardized and modular design as much as possible and strictly abides by the international, domestic and industry standards of related technologies to ensure the openness and transparency between systems and the interconnection between systems. Considering that the entire system is constructed in stages, when designing the system, for the subsystems with expansion requirements, when designing and selecting equipment, the margin design should be carried out on the basis of scientific prediction of future business growth and expansion, and the expansion should be reserved. and room for development.
4) Unification of reliability and security
The whole system adopts the overall design with high reliability. The selected equipment should have high safety and reliability. The key equipment or key components should adopt the backup redundancy design, and adopt mature technology to make the scheme have high reliability and strong reliability. Fault-tolerant ability, good recovery ability and lightning protection and anti-strong electric interference ability, and the design and use of this scheme will not affect the normal operation of the monitored electrical appliances in the electric field.
5) Unification of ease of management and ease of maintenance
The system should be easy to manage and maintain, and the design of information infrastructure such as computer networks should adopt a simple and easy-to-use architecture to reduce system operation and maintenance costs. In order to ensure the after-sales service of the products, domestic brand products with mature technology should be selected.
Design goals
As an important link in the construction of smart power plants, the integrated security system of xxx power plant needs to meet the requirements of intelligence, efficiency, safety and convenience. In order to meet the needs of smart power plants for the construction of comprehensive security systems, a set of smart systems supported by modern information technology and fully learning from advanced concepts and technical means such as "Industry 4.0" and "Industrial Internet" should be established. The system is supported by modern information technology, with network interconnection, information resource sharing, and complete application functions. It mainly achieves the following goals:
Ø Unified integration of subsystems
The unified monitoring, control and management of each subsystem can be compatible with multiple security business application subsystems such as video surveillance system, entrance and exit control system, intrusion alarm system, and emergency command system. Each subsystem conducts information exchange and control signaling exchange through the central platform according to the unified standard interface. The decentralized and mutually independent subsystems are centrally managed with the same environment and the same software interface, and the running status of each subsystem can be monitored.
Ø Digitization and intelligence
Using efficient data transmission technology, long-distance data transmission can be realized with very low bandwidth occupation on existing various digital transmission networks, and flexible, rich and extensive multimedia applications can be realized by combining with computer technology. Monitor, remote client, mobile phone and other means to realize real-time supervision of the system.
Ø Unified management platform
The platform also provides various basic equipment management and control functions such as codec equipment management, storage management, network management, and alarm management. By optimizing the system architecture, improving the overall efficiency of the system, making the platform's management of video surveillance systems, access control systems, intrusion alarm systems, and patrol systems more flexible and more user-friendly, providing users with a one-stop solution.
Ø Open architecture
The platform design is convenient for integration with third-party business systems, and provides a variety of access methods, which is convenient for the benefit of the original security system, and is also conducive to connecting the equipment of third-party manufacturers.
Ø Support high-definition intelligent monitoring
All-round support for front-end acquisition, encoding and transmission, video storage, decoding and playback of high-definition images, support for front-end and back-end intelligent applications, and high-definition processing and intelligent analysis are reflected in all links to achieve real high-definition intelligent monitoring.
Ø Provide statistical information
Through the existing information resources, output key information and form various statistical reports for leaders to make overall decisions;
Ø Strengthen operation and maintenance management
Using high-tech means, it can grasp the fault information such as equipment offline and abnormal work as soon as possible, and solve the fault in time, improve the operation and maintenance efficiency, and reduce the operation and maintenance cost.
