Harmonic management of wind–storage cogeneration systems based on inductive filtering technology
Numerous power electronic devices such as converters in wind–storage cogeneration systems introduce harmonic currents owing to their inherent nonlinear characteristics, considerably affecting the power quality of these cogeneration systems at grid connection points. To address this problem, a harmonic control method is proposed using induction filtering for wind–storage cogeneration systems. Next, a new topology is designed using an induction filter–based step-up transformer as the core equipment of these systems to overcome the shortcomings of traditional harmonic suppression methods. Subsequently, a mathematical model and the equivalent circuit of the induction filter–based step-up transformer are established, and the filtering mechanism and operating characteristics of the transformer are discussed. Furthermore, a simulation model is developed in the MATLAB system, and the filtering performance is simulated and analyzed under different operating conditions to verify the effectiveness of the proposed topology for harmonic suppression.
