Problems solved by technology

[0002] Marine beacon lighthouses are located in remote locations and are usually powered off-grid. Traditional marine beacon lighthouses are powered by solar energy. However, the solar power generation system cannot provide stable power for the lighthouse when there is insufficient sunlight. Therefore, this application aims to stabilize the power supply. A kind of marine beacon lighthouse power supply that uses wind power generators as the main power generation system and solar power as the auxiliary power generation system

[0018] figure 1 For the first embodiment of the present invention: figure 1 A wind power generator power supply system, which includes fan blades 41, a shaft 42, a rotor 43, a first stator 44, a second stator 45, a controller 46, a wind speed detection device 47, a rectifying device 48, an inverter device 49, Power conversion unit 54, inverter 61, DC / DC converter 56, photovoltaic cell 55, sunlight intensity collection device 59, capacitor remaining power detection device 58, first switch 50, second switch 51, third switch 52, Four switches 57 and fifth switches 60 .

[0019] The fan blades are driven by natural wind to drive the rotating shaft to rotate synchronously, and the rotating shaft rotates with the rotor to generate a rotating electromagnetic field to cut the first stator and the second stator to generate induced electromotive force. When the wind speed detection device detects that the speed of the rotor exceeds the rated speed of the motor, the controller sends a ...

Abstract

The invention discloses a power supply system of a wind turbine. According to the invention, electric power generated by the wind turbine is used for providing power for a navigational beacon. The wind turbines works in three different states based on different wind speed. When wind speed is quite fast, a second stator and a rotor form a generator for charging a capacitor. When the wind speed is quite slow, the second stator and the rotor form a motor for driving the rotor to rotate. When the wind speed is normal, the second stator and the capacitor do not work, and at this moment, only a first stator is used for providing working power supply for the navigational beacon. When the wind turbine breaks down, the capacitor is used for providing power for the navigational beacon. According to the invention, energy is saved, environment is protected and wind power utilization rate is increased.

Description

technical field [0001] The invention provides a wind power generator power supply system, and in particular relates to a device for powering a marine beacon lighthouse through wind power generation. Background technique [0002] The marine beacon lighthouse is located in a remote place and is usually powered off-grid. The traditional marine beacon lighthouse uses solar power for power supply. However, the solar power generation system cannot provide a stable power supply for the lighthouse when the sunlight is insufficient. Therefore, this application aims at stabilizing the power supply. A power source for a marine beacon lighthouse that uses wind power generators as the main power generation system and solar power as the auxiliary power generation system. The power supply is environmentally friendly, has high reliability, and can run off-grid. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and pro...
