Embodiment approach

[0020] Such as image 3 In the second embodiment of the present invention shown, at least two wind power generating sets share a control converter unit (54), and the converter unit can supply power to the main power distribution system (8) through the control switch (55), or Power is supplied to the ship's emergency power distribution system through the switch (56), which can save the initial cost of at least one converter unit (53).

[0021] Such as Figure 4 In the third embodiment of the present invention shown, in the case where a shaft generator set (30) with a variable flow control unit (36) is installed on the ship, the variable flow part of the variable flow control unit and the Shared by at least one wind power generator set, the electric energy generated by the fuel prime mover driving the generator set (30) and the wind power generator set (50) shares the converter unit (36), and then supplies power to the ship power grid through the switch (35). When the grid (8)...

Abstract

At present, most of ships employ fuels that are refined by using oil as a raw material as power sources. A prime mover that obtains power by relying on fuel combustion drives a generator to make operation; and electric energy is generated and is supplied to an electrical network of a ship. However, the oil price skyrockets recently and thus the operation cost of the ship is also raised; and meanwhile, due to lots of fuel consumption, pollution on marine environment is increasingly more serious. According to the invention, a wind generator system (50) and a fuel power generation system that is widely applied on a ship currently are operated in parallel, so that a mixed power supply system for a ship is formed; therefore, fuel consumption of a ship and environmental pollution can be reduced.

Description

technical field [0001] The present invention relates to a ship hybrid power supply system according to claims (1) and (2). Background technique [0002] At present, most ship generating sets are driven by prime movers (11, 21, 31, 41) based on fuel consumption to drive generators (12, 22, 32, 42) to obtain power supply. [0003] At present, there will be at least one auxiliary fuel generating set (10) and one emergency generating set (40) on board. The auxiliary fuel generating set supplies power to the main power distribution system (8) of the ship through a switch (13), and the emergency generating set passes through a switch. (43) supply power to the emergency power distribution system (7). Under normal circumstances, the emergency generator does not operate, and the main power distribution system (8) supplies power to the emergency power distribution system (7) through the switch (9). A series of electrical loads (6) on board are supplied by the main electrical distrib...
