COMPREHENSIVE INTELLIGENT SENSING SYSTEM FOR TRANSFORMER CONDITION

The onsite comprehensive intelligent sensing system for transformer status is deployed at substation sites. It consists of intelligent analysis devices, various types of sensors and a data management platform. Integrating edge computing and Internet of Things (IoT) technologies, the system adopts multisource data fusion to realize internal thermalfield calculation, dynamic evaluation of overload capacity and realtime perception of insulation status. Equipped with functions including dynamic tracking, realtime diagnosis and graded alarm, it can effectively improve the safe and economical operation performance of transformers, greatly reduce operationandmaintenance workload and maintenance costs, and provide solid guarantee for the reliable operation of substations.

TRANSMISSION LINE DYNAMIC LOAD MANAGEMENT SYSTEM

New Products / New Technology

The dynamic load management system for transmission lines is designed to improve power transmission capacity without modifying the grid structure. The system collects realtime electrical and environmental data of transmission lines. On the premise of ensuring thermal stability safety, it dynamically evaluates shortterm and longterm safe ampacity, quantifies the allowable duration under different overload multiples, and accurately avoids capacityexpansion and N1 operation risks. Providing quantitative decisionmaking support for operationandmaintenance and dispatching, the system realizes refined and intelligent load management, fully taps the transmission potential of lines, effectively relieves the pressure brought by load growth, and guarantees the safe and stable operation of the power grid.

LINE HAZARD EARLY WARNING AND FAULT PRECISION LOCATION SYSTEM

New Products / New Technology

Integrating travelingwave fault location, highprecision time synchronization and highspeed sampling technologies, this system realizes fast and accurate location of fault points in distribution networks. Installed closeby on transmission lines or poles and towers, the device can adapt to complex branchedline environments, and effectively address the drawbacks of conventional manual blind patrol, such as low efficiency and difficulty in identifying fault sections. Upon fault occurrence, the system triggers location at millisecondlevel, greatly narrowing down the troubleshooting scope, significantly shortening poweroutage duration, alleviating operationandmaintenance burdens, reducing powerfailure losses, and comprehensively improving the powersupply reliability of the power grid.
