摘要
煤矿采区供电系统运行的安全性和可靠性对煤矿的安全生产有着重要的影响。提出以继电保护为变迁集的改进Petri网故障元件诊断方法,以某煤矿采区供电系统为研究对象,对供电系统中的线路、母线、变压器、负荷等电气元件进行故障诊断建模分析。研究表明:改进Petri网的诊断方法结论准确、运算速度快,有助于提高采区供电故障的诊断能力,可促进煤矿的安全生产。
The safety and reliability of the operation of power supply system in coal mining area have important influence on the safety production of coal mine.This fault diagnosis method of improved Petri network to relay protection is set to change the power supply system of a coal mine as the research objeet,analyzed the fault diagnosis model of transformer,the power supply system of the bus line,and other electrical components.The researe.h shows that the diagnosis method of Petri nets is improved,the conclusion is aeeurate and the operation speed is fast.It can help to improve the diagnosis ability of power failure in mining area,and can promote the safety oroduetion of coal mine.
