This paper presents a study and performance of a dual rotor wind turbine with counter rotating rotor blade connected back to back on a tower to a particular electric generating unit, (permanent magnet DC generator in this case (PMDG) and the efficiency of this system is compared with the traditional single rotor wind turbine(SRWT )[1] at varying wind speed is done and to increase the relative speed between magnetic field and armature conductor ,field as well as armature is being rotated opposite of each other.
