This paper shows construction and operation principle of multipole double fed induction generator. This is low speed generator directly connected to wind turbine without gearbox. The generator is multipole and all windings are placed on stator. Rotor is tooth type without any windings on it. Primary winding is three phase and directly connected to the grid and secondary winding is two phase with power flow control and generated energy is useable for water heating, house heating system or through rectifier connected to multi energy system with DC bus bars. The main task of the power flow control is to keep the resonance mode in secondary winding at any rotation speed. For power flow control variable capacitor is used with smooth capacity variation.
