摘　　要：为解决光伏-混合储能动力船舶运行中,光伏发电和负载功率接近的临界状态下,蓄电池充放电切换频繁,船舶启动时低电压穿越(LVRT)能力差的问题,在分频协调控制基础上,充分考虑超级电容的剩余电量(SOC),提出一种可变增益值的控制策略,在电力推进负载下进行的仿真实验表明,超级电容SOC可工作在合理区间内,减少蓄电池充放电切换的次数,缩短母线电压恢复的时间。In order to solve the problems of frequent charge-discharge switching of batteries under the critical state of close photovoltaic(PV) power generation and load power in the operation of PV hybrid energy storage power ships,and poor low voltage ride-through(LVRT) capability during ship start-up,a variable gain control strategy was proposed based on the frequencydivision coordinated control and the residual power of super-capacitor(SOC) is fully considered. The simulation experiments under electric propulsion load showed that the super-capacitor SOC can work in a reasonable range,reduce the number of battery charge and discharge switching,and the time of bus voltage recovery.
