climate change effect become number one concern in many countries due to the effect that will have on human life. Renewable energy found to be one of the most effective ways to overcome this problem, wind energy is part of the renewable and one of the most growing areas in this field. In this paper the definition of switched reluctance generator and the principal of operation will be discussed, the excitation cycle and its relation to the switching parameters, methods on the switching phenomena will be discussed, low speed circuit and high speed circuit will be explained, output power of the SRM

Renewable energy systems are still much more expensive than traditional grid connected power, except in remote areas. Thus it is important that designs be optimised to achieve the least delivered energy cost over a lifetime of 20 years or so. This paper shows that to achieve grid level of reliability with wind solar and storage units alone is impossibly expensive so practical designs have always incorporated standby generation of some sort or other. This paper describes a simulation technique that enables a cost minimal, balanced system design.

A simple analytical method is developed to calculate the torque of P.M.N.R. (hybrid) torque coupler, referred as variable reluctance (V.R.) coupler. The performance of V.R. torque coupler is compared with a P.M. coupler under idealised conditions. The nonlinear effects such as leakage, fringing and saturation are ignored.A series of V.R. couplers were experimentally tested and their performance reported.
