In the context of the continuous transformation of the power system to intelligence, building an intelligent operation and maintenance system for outdoor prefabricated compact substation is of great significance for improving power supply reliability, reducing operation and maintenance costs, and improving management efficiency. Its construction strategy needs to be systematically planned from multiple dimensions.
First, building a complete data collection and perception system is the basis of intelligent operation and maintenance. High-precision sensors, including temperature sensors, current and voltage sensors, vibration sensors, gas sensors, etc., are deployed in key equipment in the outdoor prefabricated compact substation, such as transformers, circuit breakers, and mutual inductors. Through these sensors, the operating parameters, environmental data and other information of the equipment are collected in real time to achieve all-round perception of the equipment status. At the same time, the Internet of Things technology is used to uniformly encode, transmit and aggregate sensor data to provide data support for subsequent analysis and processing.
Secondly, building an intelligent analysis and diagnosis platform is the core link. Using big data and artificial intelligence algorithms, the massive data collected is deeply mined and analyzed. For example, a machine learning algorithm is used to build an equipment failure prediction model, and the possible failure type, time and location of the equipment are predicted based on historical data and real-time data, so as to achieve early warning of failures. At the same time, the expert system is used, combined with the professional knowledge and experience of the power industry, to intelligently diagnose equipment abnormalities, give accurate fault cause analysis and treatment suggestions, and assist operation and maintenance personnel to quickly locate and solve problems.
Furthermore, remote monitoring and centralized management are the key to improving operation and maintenance efficiency. By establishing a unified remote monitoring center, operation and maintenance personnel can view the operating status, equipment parameters, alarm information, etc. of the outdoor prefabricated compact substation in real time through terminal devices such as computers and mobile phones. With the help of the video monitoring system, the outdoor prefabricated compact substation site can be remotely inspected to promptly discover problems such as abnormal equipment appearance and environmental safety hazards. At the same time, through the centralized management platform, the operation and maintenance resources of multiple outdoor prefabricated compact substations are uniformly scheduled and allocated to achieve optimal resource allocation, reduce the frequency of on-site inspections by operation and maintenance personnel, and improve the response speed of operation and maintenance work.
In addition, it is essential to build an intelligent operation and maintenance decision support system. Based on data analysis and diagnosis results, the system provides scientific and reasonable operation and maintenance decision suggestions for operation and maintenance personnel in combination with the actual needs and constraints of power grid operation. For example, according to the health status and load forecast of the equipment, formulate an equipment maintenance plan to avoid excessive or insufficient maintenance; when the power grid fails or is abnormal, provide a rapid fault isolation and recovery plan to ensure the continuity and stability of power supply.
The construction of a security protection system is the guarantee for the stable operation of the intelligent operation and maintenance system. Strengthen data security management, and adopt data encryption, access control, intrusion detection and other technologies to prevent data leakage, tampering and malicious attacks. At the same time, ensure the network security of equipment and systems, strengthen the security of intelligent devices and communication networks, regularly scan and repair security vulnerabilities, establish a complete security emergency response mechanism, and ensure the reliable operation of intelligent operation and maintenance systems in complex network environments.
Finally, focus on personnel training and team building to improve the professional skills and intelligent operation and maintenance level of operation and maintenance personnel. Carry out operation training and data analysis training for intelligent operation and maintenance systems, so that operation and maintenance personnel are familiar with the functions and usage of the system, and can skillfully use intelligent tools for equipment operation and maintenance. Encourage operation and maintenance personnel to participate in technological innovation and practice, cultivate compound talents who are familiar with both power technology and information technology, and provide manpower support for the continuous optimization and development of intelligent operation and maintenance systems.
Through the comprehensive implementation of the above strategies, a set of functional, efficient and reliable outdoor prefabricated compact substation intelligent operation and maintenance system can be built, which will promote the transformation and upgrading of the outdoor prefabricated compact substation operation and maintenance mode towards intelligence and leanness, and provide strong guarantee for the safe and stable operation of the power system.
