use induction motor drive as generator?
can I use the 6 step vsi induction motor drive as a generator? I am building a IG wind turbine and and need AC-DC-AC conversion with controlled inverters which the wind turbine demos don't seem to have. ... 23 Apr 2010 17:36

use induction motor drive as generator?
I am trying to build a wind turbine with variable speed induction generator. Can I use the 6 step vsi induction motor drive model as a generator? Is there a better option? I need to have AC-DC-AC conversion with gate controlled inverters. The wind farm examples only seem to have 3 phase AC direct to the grid ... 23 Apr 2010 17:36

Design by Equivlent Cost
Hi, Following is my code for plotting the continuous closed loop poles and equivlent discrete closed loop poles for different values of R matrix.
