Estimation of wind power extraction from kites flying at high altitudes

Abstract

Estimation of wind power extraction from kites flying at high altitudes is discussed in this paper. Estimation of power generated from high flying kites using the power prediction models by Lloyd (1980) and Pauli Rautakorpi et al. (2013) is made and results were compared using same kite motion parameters such as area of kite, density of air, height of kites etc. Using the kite motion data given by Pauli Rautakorpi et al. calculations were performed for prediction of wind power generated for the mathematical model of Lloyd (1980) for the lift mode of kite motion prescribed. Calculations were made for the kite height up to 5000 m (5 km) for maximum power and power extracted from wind, for both the models. Results obtained for maximum power were compared.
