This article presents studies related to the driving and control of the switched reluctance generator in order to enhance its efficiency. This type of electrical machine is an option for wind energy conversion systems, favoring the generation of electricity in distributed generation systems and contributing positively to loads without access to the main grid. The studies developed in this paper verify the possibility of controlling the output voltage of the switched reluctance generator in parallel with an efficiency tracking technique acting on the switching angles of the power converter. Simulation and experimental results are presented in order to verify the feasibility of implementing this technique to enhance the efficiency of the generator.

Among all the renewable energy conversion systems wind energy conversion systems becoming most promising area especially at offshore locations due to availability of huge amount of wind power round the clock. This paper summarizes a review and recent advances happening in some most commonly used generators and power converters configurations at offshore/onshore wind farm.A comparison among all the different configurations has been done on the basis of fixed/variable speed operation, MPPT ability, FRT ability, power converter utilization, reactive power compensation, with and without gear-box and current market status.
