The paper presents a modelling technique and a method for determination of the windmill torque loss coefficients of a multibladed windmill. First, a new model is presented of a multibladed windmill, and the windmill torque loss coefficients are defined. Next, a measuring method based on a recursive estimation technique is developed for determination of the values of these coefficients. The torque loss coefficients are estimated satisfactorily from the simulated data and experimental data for changes in wind speed. The validity of the windmill model and the proposed estimating technique are demonstrated.
