21世纪是中国城市轨道交通的新纪元，我国已将未来城市交通轨道化发展列为今后30-50年内的重点，计划将在多座城市建设地铁和轻轨等轨道交通系统，我国轨道交通事业已经进入了一个迅速发展的新时期。尤其是位于北方地区的北京、天津、哈尔滨、沈阳、大连、西安等大城市，都在建设和规划地铁或轻轨项目。地铁系统本身是投资巨大，运行成本很高的设施，而通风空调系统又是地铁系统中耗资巨大的环节。地铁站台的通风空调系统设备功率大，运行时间长，运行能耗大。随着地铁的广泛应用，如何在保证满足站厅和站台的舒适度要求的前提下，尽可能的节约能耗，降低运行费用，是地铁系统必须考虑的问题
4结论
在国家提倡节能减排的今天，对于如何建设资源节约型和环境友好型社会，走低碳经济之路的思考已经是整个交通行业的热点问题，因此利用活塞风发电，除了大幅度降低轨道交通系统的运营费用，还将开启活塞风“变废为宝”新纪元，在我国今后地铁建设中能量利用具有深远的现实意义。
按照目前的估算，包括发电设备和安全系统，隧道内安装一个风轮的平均成本约为1000元。如果按照每隔5米安装一个风轮计算，两个站台间的隧道大约要安装320个风轮，这样一段隧道的设备投入约为32万元。如果电费按0.8元/千瓦时计算，每台风力发电机发电量计算为300千瓦时，一台风轮一年可以节省电费240元，在4-5年间可以回收1000元的设备成本。
在城市轨道交通系统内设置一定数量的风力发电机，利用活塞风发电，并将电能储存起来，便于稳定的为整个运营提供一部分电能，减少对外部能源的需求，降低运营成本，实现“变废为电”的可观效应。

按楼主要求已经翻译为英文，由于涉及到部分专业技术，请楼主针对其中涉及专业知识的部分仔细校对，以免误事。
21 Century is the era of urban mass transit, our country has the future urban transport Rails development as one of the future 30-50 Years, plans to build in many cities, such as subway and light rail transit system, our rail transportation industry has entered a new period of rapid development. In particular, is located in the northern area of Beijing, Tianjin, Harbin, Shenyang, Dalian, Xi'an, and other big cities, in construction and planning Metro or light rail project. The Metro system itself is a huge investment, operating costs are high, and the ventilation and air-conditioning system and a subway system in costly component. Metro platform of ventilation and air conditioning system device power, long-running, run the energy consumption. With Metro's widely, how to ensure that the Office and met station, platform comfort requirements, as much as possible to save energy, reduce operating costs, is the subway system must consider
4 Conclusions
In countries to promote energy conservation and emission reduction, for how to build a resource-saving and environment-friendly society, low-carbon economy of the entire transportation industry has been a hot issue, so use piston wind power generation, in addition to a significant reduction in rail transportation system of the operating costs, also will open a piston wind " treasure " new era, in China the next subway construction energy use with far-reaching practical significance.
According to current estimates, including power generation equipment and security systems, to install a wind tunnel in the average cost of about ￥ 1000 element. If according to every 5 meters installed a wind wheel calculation, the two platform between the tunnel about to install 320 a rotor, a section of tunnel device input about ￥320000. If electricity by 0.8 ￥/ kWh calculation, each wind turbine generating capacity calculated as 300 kWh, a typhoon round a year can save electricity ￥240, in 4-5 years can reclaim 1000 element equipment costs.
In urban rail transit system in a certain number of wind turbines, wind turbines, piston and energy storage, easy and stable part for the whole operation, reducing power provided on external energy demand, reduce operating costs, " implemented scrap electrical " to considerable effect.
