The electric energy generated by the wind turbines in the wind farm is boosted to 10kv level through the box transformer. It is transmitted to the substation of the wind farm through overhead lines or cables, and the substation is boosted again, and after rising to a higher voltage level (35kv, 110kv, etc.), it is merged into the power grid through high-voltage overhead lines.
Wind farms can be classified into two types: offshore and onshore. The wind conditions at sea are better than those on land, with lower rate of change of wind speed and direction, lower turbulence intensity and lower fatigue load. The life of the fan is effectively extended. Offshore wind has high availability hours and is free from dense population constraints.
As one of the main forms of clean energy, wind power generation is of great significance, according to experts’ predictions. Coal can be mined for 220 years, oil for 40 years, and natural gas for 60 years. Besides clean energy, what are the advantages of wind power?
The construction period of wind power plants is short. The installation time of a single unit is only a few weeks. The construction period of a 50,000-kilowatt capacity wind farm is about half a year to a year. The wind turbine assembly mode is flexible. The unit can be newly installed.
In the wind turbines that are more and more applied to modern technology, the reliability of wind turbines is getting higher and higher. The unit life can be as long as twenty years. At present, the cost per unit of installed capacity of medium-sized wind turbines is close to that of thermal power and lower than that of oil and nuclear power. Wind power is the cheapest source of energy if the cost of transportation into coal power and the costs associated with environmental protection are calculated.
