The invention, which relates to the technical field of ship propulsion, discloses a ship hybrid propulsion method and system. The method comprises the following steps that: if a controller sends a first instruction, a sub-controller responds to the instruction to control a first diesel engine and a second diesel engine to drive a first propeller and a second propeller; if the controller sends a second instruction, a first shaft-driven motor works in a PTO mode, a second shaft-driven motor works in a PTI mode, the first diesel engine drives the first propeller, and the second shaft-driven motordrives the second propeller; if the controller sends a third instruction, the first shaft motor works in a PTI mode, the second shaft motor works in a PTO mode, the second diesel engine drives the second propeller, and the first shaft-driven motor drives the first propeller; and if the controller sends out a fourth instruction, the first shaft-driven motor drives the first propeller to be connected or the second shaft-driven motor drives the second propeller. Under the condition that the ship speed requirements of the ship under different working conditions are met, the fuel oil utilization rate is high, and capital investment is small.
本发明公开了一种船舶混合推进方法及系统,涉及船舶推进技术领域,该方法包括以下步骤:若控制器发出第一指令,子控制器响应该指令控制第一柴油机和第二柴油机驱动第一螺旋桨与第二螺旋桨;若控制器发出第二指令,第一轴带电机工作在PTO模式、第二轴带电机工作在PTI模式,第一柴油机驱动第一螺旋桨,第二轴带电机驱动第二螺旋桨;若控制器发出第三指令,第一轴带电机工作在PTI模式、第二轴带电机工作在PTO模式,第二柴油机驱动第二螺旋桨,第一轴带电机驱动第一螺旋桨;若控制器发出第四指令,第一轴带电机驱动第一螺旋桨接合或第二轴带电机驱动第二螺旋桨。本发明在满足船舶不同工况船速要求下,燃油利用率较高,资金投入较小。
