摘　　要：短路故障是矿井提升机最严重的故障之一,短路电流特征的提取和分析对及时发现短路故障恢复生产起着重要的作用。在PSCAD/EMTDC下搭建了输电系统仿真模型,并采用C语言编程的方法对仿真模块进行了扩展。仿真结果表明,扩展的短路故障分析模块能准确地采集到短路故障电流,采用EMD分解的方法能有效地提取故障特征。Short-circuit fault is the most serious fault of mine hoist, and feature extraction and analysis of short-circuit current play a very important role in finding out short-circuit fault timely and restoring the mining production. The simulation model of transmission system was established based on PSCAD/ EMTDC, and the simulation model was extended by programming in C language in this paper. The simulation results show that the extended analytic module of short-circuit fault can collect the fault current accurately, and the EMD method can extract the fault feature effectively.
