摘 要：Wind turbine generators (WTGs) consist of many different components to convert kinetic energy of the wind into electrical energy for end users. Wind energy is accessed to provide mechanical torque for driving the shaft of the electrical generator. The conversion from wind power to mechanical power is governed by the aerodynamic conversion. The aerodynamicelectrical- conversion efficiency of a WTG is influenced by the efficiency of the blades, the gearbox, the generator, and the power converter
