Background

Wind energy, the kinetic energy produced by the flow of a large amount of air at the earth's surface. Because the temperature change is different and the content of water vapor in the air is different after the ground is irradiated by the sun, the air pressure difference of each place is caused, and the high-pressure air flows to the low-pressure area in the horizontal direction, namely wind is formed. Wind energy resources are determined by wind energy density and the number of wind energy years accumulated available. The wind energy density is the power of wind which can be obtained by unit windward area, and is in direct proportion to the third power of wind speed and air density, wherein wind energy on the offshore wind land creates more energy, and the offshore wind power is taken as a renewable energy source and is an important component of the currently required energy structure.
