The main offshore wind power models in 2023 will be models above 5 MW. Among the models sold from January to September 2022, the sales capacity of models of 3 MW and above accounted for more than 95%, and the sales capacity of models of more than 5 MW accounted for about half. Among current orders, models with a capacity of 5 MW or more account for more than 60%, and models to be delivered in the future will mainly be above 5 MW.
As of March 2020, the current price of wind power equipment is generally around 900,000 euros/MW, or 7.61 million RMB. 4 million people can buy 0.5 MW wind power equipment. The price of a 300 kW wind turbine is about 3.2 million yuan, and there are currently 0.5-2.0 MW wind power equipment on the market.
It depends on the brand you choose, the power, the type of configuration, etc. Generally speaking, theDomestic brands such as Yuchai and Weichai are relatively cheaper, while international brands like Cummins have absolutely superior technology and are relatively expensive. The higher the power, the higher the price. The configuration level also directly affects the price.
Detailed information:
The principle of wind energy production is to Use wind power to spin the windmill blades, then increase the rotation speed with the speed boost to encourage the generator to produce electricity. Depending on wind turbine technology, electricity production can begin at a breeze speed (the degree of breeze) of around three meters per second. Wind energy is becoming a worldwide craze because it does not require the use of fuel and does not produce radiation or air pollution.spherical.
The devices needed to produce wind energy are called wind turbines. This type of wind turbine can be roughly divided into three parts: the wind wheel (including the tail rudder), the generator, and the tower. (Large wind power plants basically don't have tail rudders, and usually only small ones (including domestic types) have tail rudders).
The wind wheel is an important element that converts the kinetic energy of the wind into mechanical energy. It is made up of several blades. When the wind blows toward the blades, an aerodynamic force is generated on the blades to rotate the wind wheel. The blade material requires high strength and light weight and is often made of fiberglass or other composite materials (such as carbon fiber). (There are also vertical wind turbines, S-shaped rotating blades, etc., which have the same function than conventional propeller type blades).
