西北首套特高频局放组网监测系统投用

Core Insights - The State Grid Xinjiang Electric Power Company has successfully built and operated the first high-frequency partial discharge online monitoring system in the Northwest region, marking a significant advancement in intelligent operation and maintenance of equipment in the Xinjiang power grid [1][2] - The system enables real-time monitoring of circuit breakers and GIS equipment, providing early warning and diagnosis of partial discharge, thereby greatly enhancing operational efficiency and ensuring the safe operation of the power grid [1] Group 1 - The newly established system has been in stable operation for 10 days after passing acceptance tests [1] - The GIS equipment acts as a "capsule" for the power grid, enclosing live components in a metal shell filled with sulfur hexafluoride gas, which helps prevent insulation breakdown and potential power outages [1] - Traditional maintenance methods were limited, requiring manual inspections that could take nearly a day for a single substation, making it difficult to capture sporadic discharge signals [1] Group 2 - Starting from July 2024, Xinjiang Electric Power will initiate the construction of a wired network for GIS, HGIS, and tank-type circuit breaker equipment, incorporating advanced features such as cumulative PRPD, PRPS diagram analysis, and AI diagnosis for partial discharge [2] - The new system will utilize an online platform for sound and light alarms, warning pop-ups, intelligent discharge type recognition, and three-dimensional twin model positioning, significantly reducing on-site testing time and errors [2]
