变电站数字化智能预警管控系统设计

Design of Digitized Intelligent Early Warning Control System

讨论了变电站电力系统非电量监测的"孤岛"现象、保证电力设备运行的可靠性、解决变电站无人值守的安全管理、实现无人值守变电站的远程监视等问题,通过建立数字化物联网络系统,分析了整合影响变电站正常工作因素的条件,构建了数字化预警管控系统.实现了在线监测电网环境温度、湿度、设备异常、火灾、水灾、过热、绝缘状况、局部放电等和报警功能.

The article discusses the ＂island＂ phenomenon of non-electrical monitor of substation power system, reliability of electrical equipment operation, unattended safety management of transformer substation and problem of realizing remote monitoring of unattended operation transformer substation, etc. Through establishing digitalized physical network system, factors affecting the substation work properly are analyzed, and digitalized early warning control system is built for digitizing. The warning function and the environment temperature, humidity, equipment malfunction, fire, flood, overheat, insulation, partial discharge, etc. are realized.
