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.
