Description
Technical Field
[0001] The present invention relates to the technical field of new energy power generation, and in particular to a new energy photovoltaic wind power generation system and its application. Background Art

New energy power generation is the process of generating electricity using existing technologies through the above-mentioned new energy sources. Its advantages lie in its sustainability and environmental friendliness.
[0003] Compared with traditional fossil fuel power generation, renewable energy power generation does not cause air pollution and greenhouse gas emissions. At the same time, its resource reserves are abundant and can meet human long-term energy needs. At present, wind and solar power generation are the main forms of renewable energy power generation, and the function of the power station system is simple. It is impossible to adjust the voltage of the overhead line in the field according to the loss of energy transmission, thereby increasing the transmission loss of energy. At the same time, the energy received by the power station is restricted by the environment, which makes the current inside the line easy to fluctuate during use, and then causes the system's switching unit to be damaged, increasing the maintenance cost of the later system. In addition, the existing new energy power station needs to manually adjust the direction of the equipment. When the direction of the equipment deviates from the wind or light angle, it will affect the energy utilization rate of the power station. Therefore, it is very necessary to design a new energy photovoltaic wind power generation system and its application. Summary of the invention
