Wind turbine market
1. Market demand
Wind energy is an inexhaustible renewable emerging energy source. Energy is becoming increasingly tense, and wind power generation is the first renewable alternative energy source at home and abroad. As one of the cleanest energy sources, wind power is undoubtedly one of the most competitive sources of renewable energy and is widely considered to be the most promising energy source. Wind power will be one of the most potential sustainable development projects. The state and government have elevated the wind power industry to an important position and vigorously promoted and supported it; however, at present, domestic wind power generation is dominated by horizontal-axis propeller wind turbines. This oldest wind turbine from Europe is now the most advanced modern weapon. It is purchased with huge sums of money. It is distributed in the northwest region. Large-scale grid-connected power generation, mushrooms are springing up in coastal areas. Listed companies raised huge sums of money to intervene. The support of this kind of wind turbine is seven to eight meters high and four to six meters in diameter. It is made of steel and is very expensive to build. 100 kilowatts--1500 kilowatts
The price ranges from 1 million yuan to more than 12 million yuan. Small wind turbines are distributed in areas not covered by power grids such as coastal islands, grassland pastoral areas, mountainous areas and plateaus with inconvenient transportation, and are mainly used for small household power generation. 100 watts - 800 watts
, 12 volts - 24 volts DC power generation can only be used for lighting, but cannot be used for other purposes. Medium-sized wind turbines, due to the limitations of current wind turbine models, require high wind conditions, high investment costs and inconvenient maintenance, have not been widely used in enterprises; 1 kilowatt - 100 kilowatt, priced at 9,000 yuan - -Around 1 million yuan
. To sum up the above: the domestic and international demand for wind energy is long-term, and the current wind turbine models are due to factors such as being old, expensive, and highly restrictive to wind conditions; limiting the utilization of wind energy and medium-sized wind power generation in inland areas The popularity of enterprise applications.
In response to the above problems: We have submitted two patent applications to the State Intellectual Property Office. This patented model can not only fill the gap of wind energy availability in inland areas and enterprise application of medium-sized wind power generation. space; and has the ability to replace existing models. The advantages are: the cost is quite low; regional and wind conditions are not highly restrictive. The cost of 2 kilowatts to 100 kilowatts is only about 15,000 yuan to 300,000 yuan.
The mainframe has a larger difference, and the rated wind speed can be between 6 meters/second and 8 meters/second, and can be started at 2.5 meters/second and 3 meters/second; it has broad market prospects.
2. Market price comparison
Horizontal axis wind turbine: price is about 7,000 yuan/kW-8,000 yuan/kW RMB
1500 kW: price 1050 Ten thousand yuan to 12 million yuan, tower height 70 meters to 80 meters
Rated wind speed: 12 meters/second to 14 meters/second;
Installation cost is about: 2 million Yuan - about 3 million yuan.
A repair costs hundreds of yuan
Assumption: The annual average available wind speed is about 4000 hours; not counting maintenance costs, it will take 7-8 years to make a profit.
Vertical axis wind turbine: price is about 2,000 yuan/kW to 3,000 yuan/kW RMB
1500 kW: price is 3 million yuan to 4.5 million yuan, tower height 10 Meter - 30 meters
Rated wind speed: 9 meters/second - 10 meters/second;
The installation cost is about: 100,000 yuan to 200,000 yuan.
The maintenance is low, the tower height is low, and the maintenance is very convenient.
Assumption: The annual average available wind speed is about 4,000 hours; the cost can be recovered and profitable in 2-3 years of operation.
I have now designed, manufactured, and installed a 400-kilowatt vertical-axis generator with a blade length of 30 meters, a tower height of 13 meters, and a total weight of 40 tons in a company. It is already operating normally. Suitable for areas with complex terrain, especially mountainous wind farms.
Design drawings of a vertical axis wind turbine with a capacity of 1,500 kilowatts, a blade diameter of 60 meters, a tower height of 30 meters, and a rated wind speed of 10 meters, including the wind turbine, speed increaser, tower, and pitch system have been designed Completed; the complete generator is purchased and installed.
