为了实现船舶航运事业“绿色”、“节能”的发展目标，针对某船舶设计一套同轴并联式柴电混合动力系统，通过脱模实验获得该船的阻力特性，并依据设计需求对主要部件进行选型。在选型基础上对混合动力系统搭建模型，设计一套基于逻辑门限值的控制策略实现功率分配。通过典型工况模拟仿真试验，结果显示船舶加速性能提升了10.2%，最高航速提升了7.8%，在较低航速下充电较快但油耗也更高。电力系统的使用可以有效减少污染物的排放，验证了该船混合动力系统相对于传统驱动方式具有较好的整体航行性能。
In order to achieve the green and energy-saving development goals of the ship and shipping industry, a coaxial parallel diesel-electric hybrid power system was designed for a ship. The resistance characteristics of the ship are obtained through demoulding experiments, and the main components are selected according to sailing requirements. On this basis, a model of the hybrid power system is built, and a set of control strategies based on logic thresholds are designed to realize power distribution. Through the simulation test of typical working conditions, the results show that the acceleration performance of the ship has increased by 10.2%, the top speed has increased by 7.8%, and the charging is faster at lower speeds but the fuel consumption is also higher. In addition, the use of power systems can effectively reduce pollutant emissions. It is verified that the hybrid power system of the ship has better sailing performance compared with the traditional drive.
