Wind power has become an important part of the new energy system

Wind energy, as a clean renewable energy source, is crucial to achieving the "two-carbon" goal and the transition to a low-carbon energy system.

Wind power generation is to convert wind kinetic energy into mechanical kinetic energy, and then convert mechanical energy into electric kinetic energy. Wind power industry is one of the emerging industries in China, driven by the dual policy and market demand, the national wind power industry has achieved rapid development, has become an important part of China's new energy system.

Wind is a pollution-free energy, the use of wind power is very environmentally friendly, and can produce a very large electric energy, so more and more countries pay more attention to wind power. China is also gradually developing wind power industry in the western region. In the future, with the maturity of wind power technology, more wind energy resources will be developed and utilized.

The principle of wind power

The principle of wind power generation is to use the wind to drive the rotation of the windmill blades, and then increase the rotation speed through the speed reducer to promote the generator to generate electricity. In simple terms, wind power is the process of converting wind energy into mechanical energy, and then converting mechanical energy into electricity.

Wind turbine is a power machine that converts wind energy into mechanical work, also known as windmill. Wind turbine is composed of head, rotor, tail and blade.

Wind power is divided into onshore wind power and offshore wind power.

Wind power industry chain

Wind power industry chain can be divided into upstream, midstream, downstream three links, of which the upstream for raw materials and parts manufacturing, midstream for fan assembly, core components including hub, gear box, control system, bearing, generator, as well as wind power host, tower, etc., downstream for wind farm operators, investors and wind power grid consumption.

Distribution of wind energy resources in China

China's geographical position is advantageous, onshore wind resources and offshore wind energy resources are quite rich. China's wind energy resources are mainly distributed in the northwest, North China, northeast and coastal and island areas, where the annual wind speed is above 3m/s for nearly 4000h, and the annual average wind speed in some areas can reach more than 6 ~ 7m/s, which has great development and utilization value.
