Abstract
Models are crucial in the engineering design process because they can be used for both the optimization of design parameters and the prediction of performance. Thus, models can significantly reduce design, development and optimization costs. This paper proposes a novel equivalent electrical model for Darrieus-type vertical axis wind turbines (DTVAWTs). The proposed model was built from the mechanical description given by the Paraschivoiu double-multiple streamtube model and is based on the analogy between mechanical and electrical circuits. This work addresses the physical concepts and theoretical formulations underpinning the development of the model. After highlighting the working principle of the DTVAWT, the step-by-step development of the model is presented. For assessment purposes, simulations of aerodynamic characteristics and those of corresponding electrical components are performed and compared.

Summary
The aerodynamic characteristics of vertical-axis wind turbines (VAWTs) are somewhat more complex than those of horizontal-axis configurations. VAWTs are still relatively poorly understood [1]. The Growing Interest for Vertical-Axis Wind Turbines (VAWTs). VAWTs have various advantages over horizontal-axis wind turbines (HAWTs). The main advantage is their omni-directionality; a VAWT can operate using wind incident from any direction and does not require a yaw control system. A VAWT gearbox and generator can be placed at ground level, making maintenance easier and reducing construction costs [1,2,3]. VAWTs are noiseless and do not slow wind down as much as HAWTs do, making VAWTs less detrimental to humans and birds. VAWTs can be placed close together in a wind farm [4]
