摘要
为了对城轨列车再生制动能量回馈系统的功能及系统可靠性进行验证,阐述了能馈变流器数学模型、双闭环控制策略及SVPWM调制模式,进行仿真及现场带车试验。仿真及试验结果表明:该方案能够很好地稳定直流母线电压,保证车辆的安全运行,能可靠、稳定地实现制动能量回馈功能,回馈的交流电能质量良好。
In order to verify the function and reliability of urban rail train renewable energy feedback system, mathematical model of energy feedback converter with double-loop control strategy and SVPWM modulation was built, and the simulation and test were brought out. The results showed that the renewable energy feedback system could maintain the DC bus voltage steady and ensure the safety of the train, as well as realize braking energy feeding back to the grid with good quality.
