An Engineering Calculation Method for Regenerative Braking Energy of Metro Vehicles

The feedback-based technical scheme of Metro regenerative braking energy can effectively solve the rapid transfer and comprehensive utilization of regenerative electric energy and can effectively alleviate the reverse impact of regenerative electric energy on traction power supply system. In order to quantify the feedback power capacity and optimize the train dispatching, a simple engineering calculation method of regenerative braking energy is proposed in this paper. Firstly, the basic resistance calculation model is established and the braking characteristics of the vehicles are analysed by using the actual parameters of Metro vehicles. Secondly, the calculation method of regenerative energy is deduced by the energy conversion and balance equation. Finally, the calculation procedure of regenerative braking energy is explicated by an example, and the accuracy of the calculation results is verified.
