Basis of theoretical formulations for new approach for modelling darrieus-type vertical axis wind turbine rotors using electrical equivalent circuit analogy

Models are crucial in the engineering design process because they can be used for both the optimisation of design parameters and the prediction of performance. Thus, models can significantly reduce design, development and optimisation costs. This paper establishes bases that can underlie the development of a novel equivalent electrical model for Darrieus-type vertical axis wind turbines (DTVAWTs). A brief review of existing models underscores the necessity of a new approach in modelling of DTVAWT. This work also addresses the physical concepts and theoretical formulations that can underpin the development of the model. After highlighting the working principle of the DTVAWT, the mechanic-electric analogy approach for the new model is presented. The paper ends with presentation of key lines of the theoretical formulation for the development of the new model.
