In recent years, wind power generation equipment has gradually come into everyone's vision. As we all know, wind energy is a pollution-free, renewable and very large green energy. According to statistics, the total amount of wind energy available in the world is about 53000twh / year. Assuming the large-scale development and utilization of wind energy, the use of fossil energy will be gradually reduced, and the greenhouse gas emission will be reduced It can reduce pollution, protect the environment and provide assistance for the implementation of the carbon neutralization goal. Therefore, the country has tried again and again in the direction of vigorously developing wind energy.

With the rapid development of economy and the increase of population, people have higher and higher requirements for the quality of life. The development of science and technology has brought more intelligent products and the proposal of new infrastructure concept, so that electricity has always been the fastest-growing energy in the world. The development speed of wind power generation gives people a great surprise. In Europe, wind power has been able to meet the needs of 40 million people. In some Asian countries, although they have also achieved rapid development in recent years, they still need to be improved. The advantage of wind power is that the cost will drop by 15% every time the capacity is doubled, and the growth of world wind power has basically remained above 30% in recent years.

Today, with global warming and increasingly serious environmental pollution, wind power generation can be regarded as a globally recognized scheme that can effectively mitigate climate change, improve energy security and promote low-carbon economic growth. The utilization of wind energy has attracted more and more attention all over the world and accelerated the pace of development. In order to protect the environment and achieve sustainable economic development, China is also actively promoting the development of new energy and gradually adjusting the energy structure. It is believed that in the future, with the progress of technology and the development of environmental protection, wind power generation will be able to compete with coal-fired power generation in business. At present, China's new energy strategy has focused on the vigorous development of wind power generation. According to the national plan, the installed capacity of wind power generation in China will reach 20-30 million kW in the next 15 years. With the development of wind power, its cost performance is forming a competitive advantage with coal power and hydropower. For the current wind power generation in China, the main cost lies in the maintenance of power generation devices. If the maintenance cost can be further reduced, wind power generation will play a greater potential.
