Abstract In the maximum power point tracking (MPPT) control of the power signal feedback (PSF) method for the brushless doubly-fed wind power generation system (WPGS), if the given reference power is not accurate, the system cannot follow the reference speed and cannot output the maximum power. This paper proposes a PSF control considering loss for brushless doubly-fed WPGS based on the traditional PSF method by fully considering stator, rotor copper loss and iron loss. This method obtains the iron loss accurately through the modified Steinmetz's equation. The accurate reference power is determined by analyzing the power flow of the generator, and the maximum wind energy tracking will be realized. Both the simulation and experiments on the PSF control considering loss verify the effectiveness of the proposed control strategy.

Key words： Brushless doubly-fed wind power generation system power signal feedback method maximum power point tracking loss Steinmetz's equation
