How does wind produce energy

Wind power generation means getting the electrical energy by converting wind energy into rotating energy of the blades and converting that rotating energy into electrical energy by the generator.

Wind energy increases with the cube of the wind speed, therefore WTGs should be installed in the higher wind speed area. We are working in partnership with wind turbine manufacturers to sell wind turbines and construct power plants using our sales network.

We also keep developing electronic devices including controlling systems with our knowledge and technologies cultivated from thermal and hydraulic power plant designing and manufacturing technologies while are involved in the wind power generation business on our own.

With a strength of standing on both sides, manufacturer and user, we offer solutions to meet customer needs in many different situations. In the world today, progress of technologies to develop larger WTGs are remarkable, and it makes electric output per one WTG unit increased and large field of WTGs called "wind farm" has developed.

Technologies of building offshore WTGs are progressing as well. For permanent magnet excitation, the generator achieves maintenance-free operation and reduced failure rate by removing slip rings for external excitation.

Offshore wind power offers tremendous potential. Wind turbines first emerged more than a century ago. Following the invention of the electric generator in the s, engineers started attempting to harness wind energy to produce electricity.

Wind power generation took place in the United Kingdom and the United States in and , but modern wind power is considered to have been first developed in Denmark, where horizontal-axis wind turbines were built in and a Wind is used to produce electricity using the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems.

That changes the kinetic energy to rotational energy, by moving a shaft which is connected to a generator, and thereby producing electrical energy through electromagnetism. The amount of power that can be harvested from wind depends on the size of the turbine and the length of its blades. The output is proportional to the dimensions of the rotor and to the cube of the wind speed. Theoretically, when wind speed doubles, wind power potential increases by a factor of eight.

The rotor turns the drive shaft, which turns an electric generator. Three key factors affect the amount of energy a turbine can harness from the wind: wind speed, air density, and swept area. In the U. As of the third quarter of , the U. Siting a wind farm varies from one location to another, but there are some important matters for land owners to consider: [12].

Wind power project or WPP involves development through own resources and manpower or by availing the technical services from consultant organisations: [13].

The amount of land required for a wind farm varies considerably, and is particularly dependent on two key factors: the desired size of the wind farm which can be defined either by installed capacity or the number of turbines and the characteristics of the local terrain [14]. Typically, wind turbine spacing is determined by the rotor diameter and local wind conditions.
