摘要：为研究船舶动力匹配状况，以配套某型号电控发动机的近海高速旅游客船为研究对象，分析定距螺旋浆的运行特性，采集高速客船实际航程满载、空载的运行数据，分析客船在各个工况下的转矩、转速分布特点，并结合柴油机的性能曲线分析船舶动力匹配情况。结果表明：高速客船载客数量对船舶推进特性曲线影响不大；该船舶发动机工作时能够达到额定转速和额定转矩，匹配较为合理，游船运行转矩-转速落点多在经济区域边缘。该客船配套较重螺旋桨后可将运行点向上偏移到经济油耗区。该研究可为近海高速客船动力系统配套提供参考。

Abstract：In order to study the ship power matching, take the offshore highspeed passenger ship equipped with an electronic control engine as the research object, the operation characteristics of fixed pitch propeller, the full load and noload operating data of the highspeed passenger ship during the actual voyage are collected. The torque and speed distribution characteristics of the passenger ship under various working conditions and the ship power matching in combination with the performance curve of the diesel engine are analyzed. The results show that the number of passengers carried by highspeed passenger ships has little influence on the ship propulsion characteristic curve. The ship′s engine can reach the rated speed and rated torque when working, and the matching is acceptable. The cruise ship′s running torque speed impact point is mostly at the edge of the economic region. When the passenger ship is equipped with heavier propellers, the operating point can be shifted upward to the economic fuel consumption area. This research can provide reference for the matching of power system of offshore highspeed passenger ships.
