Since renewable energies are important sources of electricity generation and rain energy increases power of wind station, this book implies rain effect on wind turbine in areas which both rain and wind exist. Furthermore turbulence is studied to obtain voltage and frequency stability in the presented wind-rain station. Besides new simulation of induction machine is applied to wind-rain station in high voltage sag and all of used wind speeds.
