基于DAB变换器的舰船中压直流混合储能系统端电压限制

摘要
为解决脉冲负载投切对舰船中压直流(medium voltage direct current,MVDC)电力系统的冲击,引入基于双有源桥(dual active bridge,DAB)变换器的锂电池-超级电容混合储能系统。鉴于传统功率分配策略无法实现对超级电容端电压的主动限制的缺点,引入混合储能系统功率比的概念,建立锂电池功率传输与超级电容功率传输之间的联系;结合DAB变换器电压变比匹配度,提出一种新型动态补偿功率分配策略;采用直接功率控制在MATLAB/Simulink中进行仿真。结果表明,这种策略能有效平复脉冲负载投切对直流母线的冲击,实现闭环功率分配,对超级电容端电压进行主动限制,从而新型动态补偿功率分配策略的有效性得到验证。
In order to solve the impact of pulse load switching on the ship medium voltage direct current( MVDC) power system,a hybrid energy storage system of lithium battery and super capacitor based on dual active bridge( DAB) converters is introduced. Because the traditional power allocation strategy can not realize the active limit of the super capacitor voltage,the concept of the power ratio of the hybrid energy storage system is introduced to establish the connection between the lithium battery power transmission and the super capacitor power transmission. Combined with the matching degree of the voltage variation ratio of DAB converter,a new dynamic compensation power allocation strategy is proposed. The direct power control is used to simulate the power distribution in MATLAB/Simulink. The results show that this strategy can effectively counteract the impact of pulse load switching on DC bus,realize closed-loop power allocation,and actively limit the super capacitor voltage,thus the effectiveness of the new dynamic compensation power allocation strategy is verified.
