Abstract :
The fluctuation of output parameters of a wind farm due to the randomly varying wind speed is a serious problem especially for fixed speed wind generators, like induction generator (IG). This paper presents a new technique to improve the performance of a fixed speed wind generator by using permanent magnet synchronous generator (PMSG) along with a storage device. A wind farm of a total capacity of 12 MW has been used for this purpose. It is shown that the output power of an IG based wind farm can be made smooth by including PMSG with it. In this concept, the power capacity required for a storage device can also be reduced. A low pass filter has been used to calculate the required capacity of the storage device. Simulations have been done by using the engineering software PSCAD/EMTDC. Real wind speed data have been considered for this study.
