Against the backdrop of accelerating the construction of new infrastructure, the intelligent transformation of the power supply system has become a key measure to ensure the safe operation of key locations. In response to high reliability demand scenarios such as education parks and transportation hubs, the new generation of power equipment state perception and intelligent operation and maintenance solutions are demonstrating their value. By building a comprehensive monitoring network and intelligent analysis platform, they are strengthening the power security defense line for critical infrastructure.

In the field of education, this system breaks through the traditional distribution room management mode by deploying high-precision sensing terminals to implement the core nodes of the campus power grid7×24Hourly status monitoring. It is worth noting that its self-developed multi-mode sensor array can synchronously capture parameters such as electric field fluctuations, ultrasonic signals, temperature changes, etc., and combine edge computing technology to achieve local data pre-processing. The monitoring response speed reaches microsecond level. intest experimentIn China, the system successfully alerted early insulation defects in cable joints, avoiding large-scale power outages and ensuring the continuity of teaching and research activities.

In response to the special needs of transportation hubs, enterprises have launched intelligent operation and maintenance solutions for power facilities suitable for rail transit scenarios. intest experimentThe deployed intelligent monitoring network covers the core equipment of the traction power supply system, and adopts special sensors designed to resist electromagnetic interference, which can work stably in strong magnetic field environments. The built-in intelligent diagnostic engine of the system integrates deep learning algorithms, which can automatically identify weak discharge features and improve the accuracy of fault warning compared to traditional methods. Practical application shows that this solution improves equipment inspection efficiency, shortens response time to sudden failures, and significantly enhances the reliability of power supply in hub stations.

Technological innovation is more reflected in the design of system level solutions. Withtest experimentFor example, the project team has built a full chain monitoring system covering substations, ring main units, and high-voltage cables. By deploying fiber optic sensing networks in underground utility tunnels, distributed monitoring of transmission channels can be achieved. The digital twin platform developed in conjunction with it can map the status of physical equipment in real time, and generate dynamic risk assessment reports by combining multidimensional information such as meteorological data and load curves. This predictive maintenance mode enables equipment maintenance to be carried out from'Plan to repair'transform into'Status repair'Extend the service life of the equipment.

It is worth noting that this solution complies with the requirements of network security level protection, uses domestic commercial cryptographic algorithms to ensure data transmission security, and stores monitoring data and diagnostic results in the local security domain. system supportIEC 61850TheModbusBy following mainstream industrial protocols, it can seamlessly integrate with existing scheduling systems and assist users in building protection systems that comply with equivalent standards.

Currently, with'carbon peaking and carbon neutrality'The strategy is being implemented in depth, and the intelligent upgrading of energy infrastructure is accelerating.
