摘要
接触网覆冰是地铁供电系统面临的一种自然灾害现象,严重威胁行车安全。本文提出一种基于四象限运行的双向变流装置融冰技术,主要研究了双向变流装置与整流机组、双向变流装置与双向变流装置两种环流融冰接入方案,以及不同环境温度下的临界融冰电流计算方法和协调控制策略。通过仿真实现了接触网融冰电流可控,验证了两种环流融冰模式与控制策略的可行性。
Icing on OCS is a natural disaster that the metro power supply system will be facing and it will severely endanger the train running safety.The paper proposes a four-quadrant operation based on bidirectional converter de-icing technology,studies mainly on the two introduced schemes of two types of loop current de-icing by bidirectional converter and rectifier unit,bidirectional converter and bidirectional converter as well as the critical de-icing current calculation method and coordinated control strategy under different ambient temperatures.Through simulation,the control of de-icing current for the OCS is realized,and the feasibility of the two circulation modes and control strategies are verified.
