A computational modelling of wind turbine mechanical power and its improve factor determination

A Wind Turbine Simulator is developed and presented in this paper to model and analyse the performance of a horizontal axis wind turbine mechanical power with its effective and improve factors. The effective factor is used to determine the effectiveness of wind turbines to extract wind energy for a specific wind speed with different number of blades. The improved factor is used to determine the improved performance of wind turbine with the increment of turbine blades. The improve factor for one to six blades of a wind turbine is evaluated based on three different commercial wind turbine parameters. The computational simulation results show that wind turbines rotating at low wind speed performs better with more turbines blades due to unity effective factor. High improve factors of a wind turbine can be achieved from the increment of one to two blades and two to three blades. This paper contributes to the computational simulation evaluation of effective and improve factors for the determination of a suitable blade configuration in a wind turbine design with a given constraint on the mechanical output power.
