Embodiment Construction
[0015] figure 2 It is a schematic circuit structure diagram of a wind-solar hybrid power generation system according to an embodiment of the present invention. Such as figure 2 As shown, the wind-solar hybrid power generation system of the present invention includes a photoelectric branch circuit formed by photovoltaic panels 11 and diodes 12 in series, and a wind power branch circuit formed by wind power generators 13 and rectifier bridges 14 in series. The photovoltaic panel 11 generates direct current under the action of the photoelectric effect, and the diode 12 in the photoelectric branch is used to prevent that when the voltage of the battery 16 is higher than the voltage of the photovoltaic panel 11, the battery 16 reversely charges the photovoltaic panel 11 and seriously affects the photovoltaic panel 11 service life. The wind power generator 13 uses wind energy to generate AC power, and the rectifier bridge 14 in the wind power branch circuit is used to rectify th...

The invention discloses a wind and photovoltaic hybrid power generation system comprises a photoelectric branch formed by serially connecting a photovoltaic panel with a diode, and a wind power branch formed by serially connecting a wind driven generator and a rectifier bridge, wherein the photoelectric branch is connected in parallel with the wind power branch for charging a storage battery in a trunk, and BUCK circuits are serially connected into the photoelectric branch and the wind power branch. The wind and photovoltaic hybrid power generation system is also provided with an MPPT (Maximum Power Point Tracking) control device capable of controlling the photoelectric branch and the wind power branch alternatively. According to the wind and photovoltaic hybrid power generation system, the defects of waste of clean energy and lower charging efficiency of the storage battery because the output power of the wind driven generator and the photovoltaic panel of the existing wind and photovoltaic hybrid power generation system is far less than the maximum output power are overcome, the maximum output power of the wind driven generator and the photovoltaic panel can be tracked so that the output power of the wind driven generator and the photovoltaic panel, and thus the wind energy and optical energy can be fully utilized.
Description
technical field [0001] The present invention relates to a power generation system. Specifically, it is a wind-solar complementary power generation system. Background technique [0002] With the development of the economy, human beings' demand for energy is also increasing, and the traditional energy reserves are increasingly depleted. Moreover, the extensive use of traditional fuels is increasingly harmful to the human living environment, and the development and utilization of renewable clean energy has become an important and urgent issue. Wind energy and light energy in clean energy are energy sources with great development value. Among them, the wind and light hybrid power generation system is a device that can simultaneously use wind energy and light energy to generate electricity. The working principle of the wind and light hybrid power generation system is: on the one hand, use natural wind as power , the wind wheel absorbs the energy of the wind, drives the wind gen...
