The integrated online monitoring system for transmission lines, in accordance with the State Grid's "three types and two networks" construction requirements, achieves multi-dimensional and precise perception of transmission line operation status through four types of equipment state sensing methods: equipment body monitoring, channel monitoring, intelligent inspection, and mobile operation. It continuously constructs an online monitoring system with panoramic equipment status and intelligent data analysis, providing safety guarantees for the reliable operation of power grid lines.
The online monitoring system for transmission cables and channels fully considers the operational status of suppliers and users in the power industry, as well as some existing problems in the current monitoring systems for underground power cable networks. Adhering to the principles of technical reliability and advancement, scalable architecture, system compatibility and stability, and the balance between cost and maintenance, it establishes a scientific online monitoring system for cable bodies and their environment. The system utilizes the most advanced intelligent monitoring and IoT technologies, relying on the power network management information platform architecture, and can continuously and reasonably achieve cable online monitoring based on the continuous growth of the information platform.
The power distribution and transformation monitoring system evaluates the status and remaining lifespan of electrical equipment using a comprehensive assessment model based on multi-information fusion technology. It considers structural characteristics, operational history, and environmental factors to analyze existing or potential faults, determining their nature, type, severity, and causes. It predicts trends and consequences and proposes effective countermeasures to prevent accidents, ensuring safe, reliable, and normal operation of the equipment.
The power safety management and control system leverages cloud computing, IoT, and AI technologies to integrate advanced technical safeguards with traditional personnel protection measures, enabling 24/7 automated monitoring at work sites. Through 3D protection of risk zones, real-time alerts for violations or external damage, and proactive hazard management, the system eliminates operational accidents and maximizes personnel safety. It also utilizes multiple advanced technologies for intelligent safety management at various power construction sites and warehouses.
The substation grounding grid condition detection system injects variable-frequency excitation current into the grounding grid through surface grounding down conductors. It measures the induced surface magnetic flux density and coordinates, employs differential algorithm-based detection to generate topological diagrams, conducts corrosion analysis and defect localization for horizontal grounding grids, providing basis and decision-making support for on-site excavation.
