* USA, China, Germany, Spain and India share major part of wind energy generation.
* Vestas Wind Energy Systems and General Electric are the major players in this technology.
* Patenting activity has seen high growth rate in the last two years.
* Research activity mainly going on rating and controlling of the Doubly-fed induction generation systems. Out of 140 patents 120 patents are discussing about controlling the DFIG
* Continuous Operation of the DFIG system during weak and storm winds, during grid voltage sags and grid faults is one of the main concerns to the companies.From articles
* Woodward Seg is a new and fast developing player in this technology.
* Brush-less operation technology reduces the wear and tear and increases the efficiency and life of the system. This technology is protected by small players, in which Dual Stator Technology Corp plays major role.<br><br><br>
=Introduction=
* Humans have been using wind power for at least 5000 BC to propel sailboats and sailing ships, and architects have used wind-driven natural ventilation in buildings since similarly ancient times. The use of wind to provide mechanical power came later.
* Existing market and future market prediction for wind energy based power generation is presented
