In the wave of intelligent transformation of energy infrastructure, the reliability of power equipment is directly related to the safety of the power grid and the stability of energy supply. With the increasingly complex operating environment of equipment, the traditional regular maintenance mode is no longer able to meet the efficient operation and maintenance needs of modern power grids. A new generation of device health management solution based on multi physics field coupling perception and artificial intelligence analysis, which constructs a complete closed-loop from perception to decision-making, providing a solution for power equipment'Intelligent Protection'.

The core of this plan lies in breakthrough multidimensional monitoring technology. By deploying high-precision sensing units at key equipment nodes, multiple types of physical signals such as electricity, sound, and heat can be synchronously captured. These miniature intelligent sensors are designed to resist electromagnetic interference and can operate stably in strong electric field environments. Their sampling frequency reaches the microsecond level, ensuring that no transient anomalies are missed. More importantly, a self-organizing network is formed between monitoring nodes, and data is preprocessed locally through edge computing, effectively reducing transmission bandwidth requirements and improving the system's real-time response capability.

At the data processing level, the independently developed intelligent analysis engine has built a three-layer protection system. The first layer establishes a digital twin model for the normal operation of the equipment through time-frequency domain feature extraction technology; Middle level application of deep learning algorithms for correlation analysis of multi-source heterogeneous data, identifying early defect features such as weak discharges; At the top level, a dynamic risk assessment report is generated based on the equipment ledger and operating conditions. This hierarchical diagnostic mechanism enables the system to capture nanosecond level pulse signals while eliminating environmental interference, resulting in improved fault identification accuracy compared to traditional methods.

In the testing experimentThe deployed intelligent monitoring network provides early warning of internal insulation defects in equipment to avoid economic losses caused by unplanned shutdowns. In response to the dispersed characteristics of new energy station equipment, the system supports wireless networking and solar power supply, achieving cluster management of hundreds of devices, improving inspection efficiency and equipment availability.

Technological innovation is more reflected in predictive maintenance capabilities. The built-in expert knowledge base of the system integrates equipment failures and simulates defect evolution paths through digital twin technology. When abnormal trends are detected, intelligent work orders containing disposal suggestions, spare parts requirements, and maintenance schedules can be automatically generated, achieving full process digitization from status monitoring to maintenance decision-making.

It is worth noting that this solution complies with the requirements of the Cybersecurity Law and the Data Security Law, uses national encryption algorithms for transmission, and stores monitoring data and diagnostic results in a local security domain. system supportIEC 61850By adopting mainstream communication protocols, it can seamlessly integrate with existing dispatch automation systems and assist power enterprises in building a security protection system.

Currently, with the acceleration of the construction of new power systems, equipment health management is shifting from'Passive maintenance'to, toward, at, facing'proactive prevention'Transformation. This innovative practice of integrating perception, artificial intelligence and industrial Internet is not only for the installation of electrical equipment'Smart Brain', even more pioneering'monitoring-diagnosis-predict-decision'The new four in one operation and maintenance model has built a solid digital barrier for the safe operation of energy infrastructure. In the future, with5G+With the deep integration of industrial Internet technology, equipment health management will move towards a new stage of more intelligence, accuracy and efficiency.
