严寒地区环控系统利用再生制动能量探讨分析

Discussion and Analysis of the Metro Environment Control System Using Vehicle Regenerative Braking Energy in Cold Region

研究目的:冬季严寒地区地铁内部的防寒保温是地铁系统应重点考虑的问题,地铁列车再生制动能量回收是目前地铁系统节能运行的一项措施。本文从环控系统的角度分析地铁列车再生制动能量回收,对严寒地区冬季地铁环控系统利用列车再生制动能量进行探讨分析。研究结论:(1)严寒地区推荐采用列车再生制动能量回收方式:再生电能一部分被返送到牵引网,被线路上其他处于牵引状态下的车辆吸收,剩余的再生电能通过车辆上设置的辅助逆变器转变为交流电,被车辆的辅助用电设备所利用或车载的吸收装置以发热的形式散发到地铁隧道内;(2)再生制动能量回收方式可以实现再生电能被同行车所吸收,降低牵引制动能耗;(3)再生电阻由地铁列车车载,不能吸收的电能以热的形式散发到地铁隧道内,夏季、过渡季靠列车活塞风就可以排除,不增加额外的环控系统能耗,从整个地铁系统综合节能考虑,应优先考虑这种列车再生制动能量回收方式;(4)本研究结论可为严寒地区地铁环控系统利用再生制动能量回收提供参考。

Research purposes： The cold insulation of metro system in winter should be focused. The vehicle regenerative braking energy is a measure of energy saving operation of the subway system. In this paper, the vehicleregenerative braking energy recovery is analyzed from the point of view of the environment control System. The metroenvironment control system in cold region using vehicle regenerative braking energy are analyzed and discussed. Research conclusions：（ 1 ）Train regenerative braking energy recovery mode is recommended： regenerative electric energy is a part of the traction network, the other is absorbed by vehicle in the traction condition, the remaining renewable power can be set up through the vehicle auxiliary inverter into alternating current, the vehicle＇s auxiliary power equipment used or car mounted device in the form of heat emitted into the subway tunnel. （2）This regenerative braking energy recovery mode on the one hand can realize that the electric energy is absorbed by the counterparts, reducing traction braking energy consumption. （3）On the other hand, the electric energy can be excluded from the subway train car, which can be emited into the subway tunnel, in summer the transition season can be ruled out by the column car, no additional energy consumption. （4）The research conclusion can provide a reference for the vehicle regenerativebraking energy recovery in the cold area.
