【摘要】 随着新技术、新设备的广泛应用,由于全电力推进的船舶电力系统与陆地电力系统的差别,需要对全电力推进的船舶电力系统进行建模与数字仿真。本文研究了采用全电力推进的船舶电力系统的数学模型,并利用Matlab初步实现了该系统的数字仿真。仿真采用了分层结构和模块化设计,具有进行船舶电力系统的稳态、动态仿真以及交流系统谐波分布计算的功能,算例证明了该仿真模型和方法的正确性。更多还原

【Abstract】 With the broad application of advance technology in ship power system, and its differences from the terrestrial power system, it is necessary to build up the model and simulation of ship power system. In this paper, a mathematical model of a complete ship electric propulsion system, including components as generators, excitation and governor system, variable speed thruster drives based on Direct Torque Control, is presented. And some static simulations such as power factor of power plant and efficiency of generators, and dynamic simulations such as dynamic response of voltage and frequency of generator and speed and torque of propulsion motor, as well as harmonic distribution of ship power system are shown clearly through simulation system in Matlab. The validity of mathematical model is testified through a real system.更多还原
