Parameter estimation of output power curves for some current smallscale wind turbines

Resumo

The assessment of estimated output energy is a key issue in the design and sizing of wind generation projects. Further, its accuracy and reliability can benefit from the use of actual power curves of wind generators that furnish the response of the generator to the wind regime under consideration. The unavailability of studies of this nature for small-scale wind generation is presumably a limitation for autonomous investments in wind energy. In this paper, we estimate the parameters of the power curves of five small-scale wind generators currently available. The results are presented as analytical performance curves that can be directly used in assessing their power output as subject to a given wind regime, thus providing a practical and straightforward tool for power potential assessment.
