摘要
在船舶电力系统中引入储能技术可以解决由于负载频繁变化带来的问题。文章主要针对由电池和超级电容组成的混合储能系统进行研究,提出了一种应用于推进系统和脉冲功率负载的新型电池/超级电容混合储能系统,利用双有源桥的拓扑,通过移相控制能量双向流动,实现电池和超级电容的充、放电。新型混合储能系统可以提高船舶电力系统稳定性和可靠性、提高燃油利用率、减少有害气体排放,是船舶电力系统发展的新方向。
The introduction of energy storage technology in ship electric power system can solve the problems caused by load changes continually. This paper explores a battery/ultracapacitor energy storage system. A new configuration of the battery and ultracapacitor combined system is introduced for propulsion system and pulse power loads. A dual active bridge topology is selected to control the bidirectional power flow through phase shifting for charging and discharging batteries and ultracapacitors. The new hybrid energy storage system can improve the stability and reliability of the ship electric power system, can improve the fuel ejficiency and reduce the harmful gas emission, which is the new direction of the ship power system development.
