本文首先对城市轨道交通地铁再生制动能量逆变回馈吸收系统的构成及工作原理进行了分析,然后在MATLAB中搭建了基于SVPWM控制的逆变回馈型再生制动能量吸收系统的仿真模型(包括主电路和控制电路模型)。仿真结果表明:该模型能满足地铁列车再生制动能量的吸收利用以及达到稳定牵引网电压的要求,可为实际工程问题提供参考。
In this paper, the composition and working principle of regenerative braking regenerative braking energy absorption system of metro in urban rail transit are firstly analyzed. Then a simulation model of regenerative braking regenerative braking energy absorption system based on SVPWM control is built in MATLAB Main circuit and control circuit model). The simulation results show that the model can meet the demand of regenerative braking energy of subway train and achieve the requirement of stable traction network voltage, which can provide reference for practical engineering problems.
