Background technique

With the development of science and technology and the continuous improvement of human living standards, non-renewable resources have been extensively exploited and destroyed by people, and are facing the trend of depletion, which has triggered an energy crisis. In order to achieve the sustainable development of energy, on the one hand, my country must "open source" and develop clean energy such as wind energy, photovoltaic, solar energy, biomass and energy, and on the other hand, it must "reduce expenditure", that is, adjust the energy structure and vigorously implement energy conservation. emission reduction. As a green, clean and renewable energy source, wind energy is becoming more and more important. Using wind energy to generate electricity will largely achieve the goal of energy conservation and emission reduction.

Most of the current wind turbines are intelligently adapted to be used in places with sufficient wind sources and concentrated wind power. If they are used in areas with low wind power and low wind speed, they will not be able to generate electricity normally, which will bring great limitations to the full utilization of wind power natural resources. And because the current wind power station usually consists of dozens of turbines and hundreds of blades, not only the cost of manufacturing, transportation and installation of the equipment is high, but also the engineering is complicated. In addition, tall wind turbine towers standing on the ground will kill birds and cause damage to the ecological environment to a certain extent. Therefore, it is necessary to propose a safe and efficient power generation system that can adapt to various wind field environments and utilize breeze power generation.
