摘要：为顺应并推动绿色旅游船舶的发展，针对传统柴油机动力污染严重的问题，开展对岛际小型旅游客船“油改电”的研究。本文选取了刘公岛客运中心一艘小型旅游客船作为目标船舶，基于该船船体参数对其运行阻力、有效功率进行计算设计。基于计算数据利用MATLAB软件确定出推力系数和扭矩系数与进速比之间的函数关系、船舶阻力与航速的函数关系，建立船舶推进电机运动系统。通过机桨匹配计算数据选取合适的推进电机，并利用Simulink仿真搭建基于空间矢量控制（SVPWM）的推进电机模型。通过Simulink仿真结果，分析该船典型工况下的变化曲线，证明了目标船舶电力改造的方案合理可行，为在实际工程中应用提供理论依据。

In order to comply with and promote the development of green tourist ships, aiming at the serious pollution of traditional diesel power, the research on "replacing oil with electricity" of small inter island tourist ships is carried out. In this paper, a small tourist ship in Liugongdao passenger transport center is selected as the target ship, and its running resistance and effective power are calculated and designed based on the ship hull parameters. Based on the calculation data, the functional relationship between thrust coefficient, torque coefficient and speed ratio, and the functional relationship between ship resistance and speed are determined by using MATLAB software, and the ship propulsion motor motion system is established. The appropriate propulsion motor is selected through the propeller matching calculation data, and the propulsion motor model based on space vector control (SVPWM) is built by Simulink simulation. Through the Simulink simulation results, the change curve of the ship under typical working conditions is analyzed, which proves the rationality and feasibility of the target ship power transformation scheme, and provides a theoretical basis for practical engineering application.
