Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] This multi-working condition oil-electric hybrid propulsion system suitable for small high-speed unmanned boats includes a fuel tank 1, a fuel supply pump 2, an engine 3, a first clutch 4, a second clutch 5, a power separation and synthesis device 6, and a main generator / auxiliary motor 7 , main motor / auxiliary generator 8 , first converter 9 , second converter 10 , lithium-ion battery pack 11 , battery power charger 12 and propeller propeller 13 . When the unmanned vehicle is in different working modes, the number of parts involved in the work in the system is different, and its power and power (mechanical force) transmission routes are also different. Since the marine engine cannot output a large torque in the low speed area, the electric motor can efficiently complete the start in the low speed area. Therefore, at the beginning of the voyage of th...

Abstract

The invention provides a multiple working condition gas-electric hybrid propulsion system applied to a small-size high speed unmanned ship, and belongs to the technical field of ship power systems. The propulsion system is mainly composed of an engine, two clutches, a power separation and synthesis device, a main electric generator/auxiliary electromotor, a main electromotor/auxiliary electric generator, two converters, a lithium-ion battery pack, a battery power charger and a propeller. The propulsion system can form three working modes including pure electric, gas-electric light hybrid and gas-electric high hybrid, and the three working modes can be switched according to actual working conditions. According to the propulsion system, through the effective cooperation of the engine and the electromotor, the characteristics that the electromotor has large torque and high power output at a low rotation speed and the high power output of the engine appears in the high rotation speed zone are fully utilized, the engine and the electromotor are enabled to always work in the maximum efficiency zone, good fuel economy and emission performance can be achieved; and meanwhile, the reliability and maneuverability of the ship are improved, cruising power and self-control ability are enhanced, and the propulsion system has the capacity for being applied to multiple working conditions.

Description

technical field [0001] The invention relates to a multi-working-condition oil-electric hybrid propulsion system suitable for small high-speed unmanned boats, belonging to the technical field of ship power systems. Background technique [0002] In the process of globalization, ships and shipping have played an irreplaceable role, but at the same time, the speed of the ship and shipping industry in controlling greenhouse gas emissions and addressing climate change is far behind the decarbonization process of other industries around the world. Changing the development mode and developing green shipping has become the consensus of the shipping industry and even the entire shipping industry. The oil-electric hybrid ship has become a hot topic in the shipbuilding industry due to its advantages in economy and environmental protection. [0003] At present, the main modes of domestic and foreign oil-electric hybrid ship power systems are: series diesel-electric hybrid power system; ...
