井下变电所无人化智能供电系统研究

Research on Unmanned Intelligent Power Supply System of Underground Substation in Coal Mine

为解决某矿供电系统存在的"短路越级、失压群跳、漏电误动拒动"等问题,实现井下变电所无人值守的目标,对某矿供电系统进行升级改造,采用KJ698煤矿无人值守智能供电监控系统,通过通讯信号传输,地面监测井下供电系统状态和运行情况,使供电系统智能化、可视化,减少故障和事故,确保供电系统安全稳定运行。

In order to solve the problems of"short-circuit overstepping,group tripping due to loss of voltage,leakage and misoperation and refusal"in the power supply system of a certain mine,and to achieve the goal of unattended underground substation,the power supply system of a certain mine was upgraded and transformed,and KJ698 coal mine was used.The human-on-duty intelligent power supply monitoring system monitors the status and operation of the underground power supply system through communication signal transmission,making the power supply system intelligent and visualized,reducing faults and accidents,and ensuring the safe and stable operation of the power supply system.
