A solution for the conventional wind farms by using semi-converter based PMSG with a higher capacity

The performance of induction generator (IG) based wind farms is not satisfactory these days. The existing IG based farms create a huge problem especially in case of expanding the capacity of the wind farm. This paper introduces a new solution for the problem. It suggests that the introduction of permanent magnet synchronous generator (PMSG) with IG, not only expands the capacity of the wind farm, but also it produces a stable output. A practical case considering Synchronous Generator (SG) in combination with a wind farm having both IG and PMSG has been used. The proposed PMSG has been equipped with the full-rated power converters. The results prove the effectiveness of the proposed model. Simulations have been done by using the engineering software PSCAD/EMTDC. Real wind speed data have been considered for this study.
