It depends on the annual average wind speed in the area where your wind farm is located, the annual unavailable wind speed (that is, less than 3.5m/s and greater than 25m/s), the availability coefficient of the wind turbine, and the power curve of the generator. , generally it should be equivalent to about 2000 hours of full power, that is, 1500 (kw) x 33 x 2000 (h) = 100 million degrees.
How many kilowatt-hours of electricity does one circle of wind power produce?
The annual power generation of 5 MW is about 7 million kilowatt-hours. The installed capacity is 5 megawatts, or 5,000 kilowatts, and the power generation per hour is 5,000 kilowatt hours, or 5,000 kilowatt hours. Taking into account the influence of geographical location, sunlight intensity and overall weather, the annual utilization time of photovoltaics is about 1,400 hours, so when multiplied, it is 7 million kilowatt hours.
Wind power generates 2 kilowatt hours of electricity per revolution.
The power of commonly used wind turbines in China is about 2000KW. When the wind is good, each device can generate about 2 kWh of electricity when it rotates once. Although wind power generation relies on wind power, it is unstable. As long as the wind speed can reach 3 meters per second, it can generate electricity. And in terms of consumables, it can be said to be "zero cost".
Compared with thermal power generation, wind power generation can be said to be low-cost and high-profit. Depending on the power of the wind turbine, there are certain differences in the amount of electricity that can be generated. The amount of power generated by one rotation is also fundamentally related to the power. Generally, a generator set with a power of 1500KW can generate 1500 kWh of electricity in one hour.
Wind power generation prospects
The development prospects of China's wind power and other new energy power generation industries are very broad, and it is expected to maintain rapid development for a long time to come. Profitability will also steadily increase as the technology matures. After 2009, the total profit of this industry will maintain rapid growth, and the growth rate will also reach more than 60%.
With the development of wind power, its cost performance is forming a competitive advantage with coal power and hydropower. The advantage of wind power is that every time the capacity is doubled, the cost drops by 15%. In recent years, the growth of world wind power has remained above 30%. With the localization of China's wind power installed capacity and the scale-up of power generation, the cost of wind power is expected to drop further. Therefore, wind power has begun to become a place for more and more investors to pursue gold.
