In recent years, China began to develop the light rail transit and subway. The subway stations has shorter distance and locomotive has haig density running. During locomotive frequently braking, it produced considerable regeneration energy. Reasonable utilization of the regeneration energy not only save energy, protect environment but also reduce the regeneration energy not only save energy, protect environment but also reduce the voltage grade for the locomotive’s safety operation. This paper is the focus on utilization of the regeneration energy, and The inverter-resistance hybrid method is propose. This topic is purposed to build Metreo regenerative braking and inverter-resistance hybrid energy absorption model by simulation software. Firstly, the urban rail transit power supply system has been introduced. Several vehicle braking scheme has been summarized and analyzed for their advantages and disadvantages. The inverter-resistance hybrid of regenerative braking energy absorption solution has been purposed. Secondly, combined with inver and resistance braking scheme, the
