¬†INTRODUCTION ¬†There has been a significant improve in wind energy generation systems throughout recent years. However, high capital investments and low capacity factors are still the remaining issues . Holding the stresses applied by the weight of the structure requires reliable foundations which considerably increases the implementation cost. The average lifetime of the conventional wind turbines is almost 20 years. However, their gearboxes should be replaced after the operation period of 5 to 7 years, and this replacement can be as costly as 10 percent of the entire turbine . In the conventional wind farms, each wind turbine is comprised of a gear box, power electronics, and a generator all implemented in nacelle. Recently, new generation of wind turbines is introduced in which a hydraulic system is designed and utilized…
