摘要
为了增强氢能源混合动力列车能量调控过程的稳定性,降低能量调控过程中对混合动力系统母线的冲击,提出了一种改进的基于规则的瞬时功率控制策略,将母线电压引入控制环节,增强了系统的稳定性.结合列车运行工况对控制策略的有效性和稳定性进行了仿真验证,仿真结果证明,优化后的控制策略提高了混合动力系统高压直流环节的稳定性,避免了对超级电容系统和牵引系统的高压冲击,有助于延长超级电容的使用寿命.
Abstract
In order to enhance the stability of energy regulation and reduce its impact on the power supply bus of hydro-gen-electric hybrid train,an improved rule-based instantaneous power control strategy is proposed,in which the bus volt-age is introduced into the control link to enhance the system stability.The simulation results prove that the optimized con-trol strategy facilitates improving the stability of high-voltage DC link of the hybrid system,avoiding high-voltage surging to the super-capacitor system and the traction system,and extending the service life of the super-capacitor.
