特大型煤矿变电所智能模拟盘

Intelligent Analog Board in Substation for Extra Large Modernized Coal Mine

介绍一特大型现代化煤矿的变电所智能模拟盘．该模拟盘能实时在线监测显示变电所主接线系统及各隔离开关和断路器的通、断状态，母线运行状态；能数字显示两路35kV电源进线的有功功率、有功电度、功率因数以及三台主变的温度；具有模拟操作演示功能、故障分析指示功能；能自动打印记录昼夜负荷参数、负荷曲线，以及显示、打印事故分析的结论．

This paper gives details of an intelligent and multiple analog board. for an extra large midernized coal mine. The functions of the system include real time monitoring, fault alarm and analogue operation. It can indicate the stare of main lines, bus wirds, all break- ers and isolating links in line. It can display the effective power, electric energy, power fac- tor of two 35kV incoming lines and the temperature of three main transformers. It can record load parameter, load curve and fault state automatically.
