Household wind driven generator with micro-power consumption

Abstract

A household wind driven generator with micro-power consumption comprises blades, a rotary shaft and a three-phase permanent magnet synchronous generator. A wind and photovoltaic hybrid control inverter replaces a wind power generation controller or a photovoltaic power generation controller or a direct-current inverter in the traditional household wind driven generator, natural wind energy and solar energy are utilized to the greatest extent, storage batteries are charged optimally, and the service life of each storage battery is greatly prolonged. Besides, power conversion with micro-power consumption is realized for all circuits, so that electric energy loss is minimized.

Description

technical field [0001] The invention relates to a household wind power generator with low power consumption. Background technique [0002] figure 1 It is a traditional domestic wind power generation system, which has the following disadvantages: [0003] 1) The output voltage of the wind turbine passes through the controller, and its output voltage is not constant. This unstable voltage charges the battery instead of constant voltage charging, which affects the service life of the battery; [0004] 2) by figure 2 It can be seen that the output voltage of the solar panel varies with the intensity of light and the size of the load. When the photovoltaic power generation voltage is directly connected to the output terminal of the wind turbine controller, and the voltage is lower than the output voltage of the wind turbine controller, the photovoltaic panel has no current. Output, only when the voltage generated by the photovoltaic panel is higher than or equal to the output...

[0003]1) The output voltage of the wind turbine passes through the controller, and its output voltage is not constant. This unstable voltage charges the battery, not constant voltage charging , affecting the service life of the battery;

[0004]2) by Figure 2 shows that the output voltage of solar panels varies with the intensity of light and the size of the load. When the photovoltaic power generation voltage is directly connected to the output of the wind turbine controller, the voltage is lower than the output of the wind turbine controller. When the voltage is high, the photovoltaic panel has no current output, and only when the photovoltaic panel power generation voltage is higher than or equal to the output voltage of the wind turbine controller, there is current output. If it is lower than the output voltage of the wind turbine controller, the photovoltaic power generation voltage will be completely wasted;

[0005]3) The output voltage of the wind generator is directly connected to the output terminal of the solar panel. When the voltage from the wind generator is lower than the output voltage of the solar panel is , the wind turbine has no current output, only when the output voltage of the wind turbine is higher than the output voltage of the solar panel, there is current output, and a lot of time is completely wasted of wind energy;

[0006]4) The controller and inverter of the wind turbine adopt the traditional power conversion method, which has low efficiency, large power loss, and strong EMI interference;
