The power generation of wind farms depends on the local wind resources and the power generation capacity of the wind turbines used. Generally speaking, they are divided into IEC Category I, Category II and Category III wind farms. Among them, Category I wind farms have the best resources, but in China most of them are Category II wind farms. Category three.
At present, mainstream wind turbines are above the megawatt level, and the power curves of imported and domestic wind turbines are not much different. When the availability is guaranteed, the equivalent hours of full load in a year should be The average is around 2,000 hours.
In this way, calculate the annual power generation of a most common 1.5MW wind turbine as 1500KW*2000h=3000000 degrees=3 million degrees
For wind power generation, how many levels of wind power are used? The concept is too crude. Due to different generator capacities, the requirements for wind speed are also somewhat different. However, generally if the wind speed exceeds 3m/s, the wind turbine can generate electricity. However, wind power generation does not depend on how high the local wind speed can reach, but on how long the local wind farm that generates electricity for this wind turbine can operate per year. Based on the current wind power subsidy price set by the state, if the power generation time is less than 2,000 hours that year, there will be no profit.
