摘要
研究了列车制动能量回馈电网的原理、功率拓扑结构、数学模型和控制算法。通过理论分析,采用Matlab仿真工具,建立了采用电流滞环SPWM控制的三电平拓扑实现列车制动能量回馈电网的数学模型和仿真模型。列车制动能量回馈电网的仿真试验表明,该系统不仅可使能量双向流动,且能有效抑制注入电网的谐波,其电能质量指标能符合相关并网标准,可考虑并网消纳回馈功率。
The principle of braking energy feedback of train and its power topology,mathematical model,and control algorithm are studied in this paper.The mathematical model and simulation model of using three-level topology which is controlled by hysteresis current SPWM to achieve braking energy feedback of train are established by using theoretical analysis and Matlab tool.The simulation of braking energy feedback of train indicates that the system can not only allow two-way flow of energy,but also suppress harmonic...
