Study on electromagnetic transient process in split-phase insulator considering viaduct’s electrical couplingbased on ATP-EMTP
摘要
Abstract
Considering viaduct pier and traction network’selectrical coupling, this paper focuses on the study of electromagnetic transient effect for electricmultipleunit (EMU) passingsplit-phase insulator, whichhas important significant to the operation safety of EMU, sincethetraction lines of HSR (high-speed railway) power traction system are mostly laid on viaduct. Firstly, equivalent circuit model including traction power supply circuit andviaduct pier loop circuit is established. Secondly, this paper analyzes and solves the coupling coefficient of viaduct pier and various electrical parameters. Thirdly,the vehicle-catenary-viaduct couplinglumped parameter model regarding each transient process for EMU passing split-phase insulator is built by ATP-EMTP. Finally,thecorresponding electromagnetic transient processes, which respectively consider viaduct or not, are simulated, and their influencing factors are analyzedindetail. The simulation results indicate that the viaduct looped circuit provides with effective discharge channel to weaken the over-voltage amplitude obviously.关键词
