| 摘 要： | 为减小推进负载扰动对船舶电力系统的影响,提出一种由超级电容构成的储能系统吸收推进负载扰动的新方法.在建立储能系统等效电路的基础上,通过引入切换系统理论,构建储能系统双向DC-DC变换器的切换系统模型,构造Lyapunov函数,进而得到系统切换律.以动态定位船为例的仿真研究表明,超级电容储能系统能够吸收低负载时的船舶电网能量,并在高负载时释放,有效降低能耗,提高推进系统性能.

| Abstract: | To reduce the effect on the ship power system caused by load power disturbance,a new method for absorbing the load power disturbance is proposed which is used supercapactors energy storage system.Based on constructing an equivalent circuit of energy storage system,the switching system model,which is for the bi-directional DC-DC coverter of the energy storage system,is established using switching system theory.And then the switch rules are obtained through constructing Lyapunov function. The simulation resul... |
