Power Quality Improvement Through Pitch Angle Control of Variable Speed Wind Turbines

Kaushal Kumar , Prof. (Mrs.) Susan S. Mathew

In this paper an improved technique for pitch angle control of variable speed winds turbines. The Wind energy, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions during operation. The world has enormous resources of wind power. It has been estimated that even if 10% of raw wind potential could be put to use, all the electricity needs of the world would be met. A phased programmer to develop wind energy in India started as early as 1985, and today the total installed capacity has reached 493.538 GW, saving about 935,000 metric tons of coal. The recent evolution of power semiconductors and variable frequency drives technology has aided the acceptance of variable speed generation systems. Such systems can yield 20-30% more power than constant-speed generation systems. This project envisages study of such technologies, their effect under various conditions & scenarios and their implementation & analyses using simulation models.
