摘要
分析了城市轨道交通列车逆变回馈型再生制动能量吸收系统的构成及其工作原理。利用MATLAB软件中的Simulink和SimPowerSystems两个工具箱建立了再生制动能量逆变回馈系统的仿真模型(主电路和控制电路模型),对其输出特性进行仿真,并利用快速傅里叶变换(FFT)分析工具对其仿真输出电压的谐波含量进行分析。仿真结果与理论计算结果一致,表明该仿真模型可以用来定量分析再生制动能量逆变回馈装置的理论输出特性。
The absorption of rail vehicle regenerative braking energy is an important ingredient of urban rail transit system. The composition and the working principles of the inverting type regenerative braking energy absorption system are ana- lyzed. A simulation model of the regenerative braking energy absorption system is established by using the software Simulink and SimPowerSystems, the output characteristics of this model are simulated, the harmonies in output voltage are analyzed by using Fast Fourier Transform Algorithm （FFT）. Since the main circuit and the controlling circuit model are designed sep- arately in the model, and the simulating instance has confirmed the correctness of the model and the simulating method, the practical engineering problems are therefore solved.
