在船舶电力系统中，船舶大功率负载的变化除了会引起船舶电网剧烈的波动，增加船舶原动机的机械应力和热应力，还会增加船舶燃料的消耗。为保证船舶电网的安全稳定，本文采用混合储能单元技术。本文分析船舶电力系统的调速系统和励磁系统，锂电池与超级大电容的充放电电路。根据锂电池和超级大电容的特性，采用粒子群算法优化混合储能单元容量。利用Matlab/Simulink仿真了含混合储能单元的船舶电力系统。仿真结果表明混合储能单元能够明显的抑制船舶电网波动，增强系统的稳定性。
In marine electric power system, the change of large power load in addition to make the ship power grid fluctuate sharply, increase the mechanical stress and thermal stress of ship engine, also increases the fuel consumption of ship. In order to guarantee the safety and the stability of the ship power grid, the hybrid energy storage technology were considered. This paper studies speed control system and excitation system of ship power grid, it also studies lithium battery and super capacitor charge and discharge circuit. According to the characteristics of lithium battery and super capacitor, the capacity of hybrid energy storage unit was optimized by using particle swarm optimization. We use Matlab/Simulink to establish the simulation of ship power system with hybrid energy storage unit. The result shows that the hybrid energy storage unit can obviously inhibit the ship power grid volatility and improve the stability of the system.
