深圳地铁2号线工程再生制动能量吸收装置设置方案研究

研究目的：选择适合于深圳地铁2号线工程特点的再生制动能量吸收装置设置方案。 研究方法：针对再生制动能量吸收装置的几种设置方案，结合深圳地铁2号线工程实践，从车辆、环控、变电所、土建几个方面，分别对车载设置方案、地下变电所设置方案、地面变电所设置方案进行较为详细的分析比较。 研究结果：根据深圳地铁2号线沿线各车站现状，采用制动电阻地面通风散热的方案不具备工程可实施性，应采用车载制动电阻，并合理解决通风散热问题。 研究结论：指出了能否合理解决制动电阻的通风散热问题是本工程选择再生制动能量吸收装置设置方案的关键。

Research on the Setting Proposal of Regenerative Braking Energy Absorbing Equipment for Shenzhen Metro Line 2

Research purposes: To choose the setting proposal of Regenerative Braking Energy Absorbing Equipment(RBEAE) suitable for characteristics of Shenzhen Metro Line 2.Research methods:Aiming at several setting proposals of RBEAE and combining with the engineering practice of Shenzhen Metro Line 2,this paper makes the detailed analysis and comparison respectively on the setting proposals of on-board equipment,underground substation and ground substation in the respects of rolling stock,environmental control,substation and civil engineering,etc.Research results:According to current situations between stations along the line of this project, it is thought that it has no execution feasibility in the engineering if the proposal of ground ventilation and heat dispersion is used for braking resistance,and should adopt the vehicle-board braking resistance to reasonably resolve the problems of ventilation and heat dispersion.Research conclusions:This paper points out whether the ventilation and heat dispersion of braking resistance can be solved reasonably or not is key factor to select the setting proposal of RBEAE.
