QUALITY IMPROVEMENTS IN WIND ENERGY GENERATION

Abstract

Wind energy is a clean and renewable energy source whose applications exist worldwide. Sun is indirect cause of wind energy. Due to uneven heating of air on earth's surface wind blows. This energy can be harnessed through windmills for several applications of mankinds. Its use is expanding. Wind energy in India is fastest growing sector, with highest capacity addition of 1112 MW in last financial year. With 45% capacity addition India ranks 4th in the world with highest growth rate. The problem associated with Wind Energy Conversion Systems (WECS) is related to the technology, which is being imported presently. No national standards for WECS in India are available as yet. This study involves an attempt to prepare a quality standard for WECS, which included: Selection of site, Mechanical equipments, Electrical components, Civil works, Installations, Operations and Maintenance for planning, designing and operation of wind farm. These components of quality standards are prepared on the basis of visiting wind farms and performance evaluation of a wind farm situated in Vijaydurg - Girye owned by MEDA, which is done on one-year generation and maintenance data collected from the site to find the expected increase in PLF by raising the height of the tower.
