摘要

本文分析了一个基于驱动逆变器和DC/DC变换器效率的案例研究，研究了配备移动储能系统的电动公共交通的制动能量再利用效率。首先对制动能量积累过程进行了仿真，然后对先前储存的能量再利用过程进行了仿真。累积过程中的损失和再利用过程中的损失从全制动能量中扣除。对新旧储能系统进行了仿真，研究了老化对储能系统的影响。

Analyses of Trolleybus Recuperation Energy Utilisation Losses Considering Different Efficiency Ratios of Traction Inverter and DC/DC Converter

The paper analyzes a case study on the efficiency of reuse of braking energy for electric public transport equipped with a mobile energy storage system depending on the efficiencies of the drive inverter and the DC/DC converter. Firstly, the simulations of the braking energy accumulation process were carried, followed by simulations of the process of reuse of previously stored energy. Losses in the accumulation process and losses during reuse were deducted from the full braking energy. Simulations of both new and used energy storage systems were carried to study also the effects of aging.
