Abstract :Wind power generation capacity in India has significantly increased over the few decades and the total installed wind power capacity has grown up to 32.72 GW insert ignore into journalissuearticles values(as on October 2017);, which ranks fourth largest in the world. The scope for wind farm as assessed using Geographic Information System insert ignore into journalissuearticles values(GIS); platform is found to be more than 2000 GW. So there is a lot of scope for expansion wind power projects provided studies are conducted on the selection of its components. One of the main components of Wind Energy Conversion System insert ignore into journalissuearticles values(WECS); is the electrical generator apart from the prime mover and other structural parts.  This paper introduces an experimental setup for the study of different types of electrical generators and their feasibility for different wind conditions. In this setup, Squirrel Cage Induction Generator insert ignore into journalissuearticles values(SCIG);, Slip Ring Induction Generator insert ignore into journalissuearticles values(SRIG);, Permanent Magnet Synchronous Generator insert ignore into journalissuearticles values(PMSG); and Permanent Magnet DC Generator insert ignore into journalissuearticles values(PMDC); are available for study. These generators are coupled to a Separately Excited DC motor via a portable coupling arrangement. The separately excited DC motor emulates the wind turbine. The results of the experimental setup are validated and presented.
