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 (as on October 2017),
which ranks fourth largest in the world. The scope for wind farm as assessed
using Geographic Information System (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 (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
(SCIG), Slip Ring Induction Generator (SRIG), Permanent Magnet Synchronous
Generator (PMSG) and Permanent Magnet DC Generator (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.
