Mathematical modelling and equivalent circuit representation of bladeless wind turbines

Abstract

This paper provides a mathematical model for the bladeless wind turbines working on vortex shedding principle. Unlike conventional wind turbines that work with rotary inputs, bladeless turbines require to generate power from vortex induced vibrations. Hence, it is required to have a mathematical model and equivalent circuit representation to help analyze the bladeless wind turbines and estimate different performance metrics. This may also be used in developing efficient control methodologies. A generalized mathematical model with three different equivalent circuit representations for the electro-mechanical system of a bladeless wind turbine is developed in this paper.
