Abstract
Over time the investments directed to the generation of wind energy are growing all over the world, with that, it is necessary to analyze the phenomena that cause the reduction in the energy production of a wind farm. One of them is the effect of the treadmill that entails a significant decrease in wind speed. In addition, there is a high investment related to an anemometric tower that could be avoided if a function was used that related the speed of the wind in the tower and the aerogenerator. Thus, the purpose of this work is to evaluate the wake effect on the energy production of the Macau mill and to determine if a transfer function could relate the wind speed in the tower and the turbine. By means of two algorithms the necessary distance was verified so that the wind power plant does not present losses in the productivity and if the function of transfer of the norm IEC 61400-12-2 would relate the measured data in the tower and the aerogenerator with precision. The results show that the ideal distance between wind turbines for a plant implemented in Macau should be 800 m and that it is possible to estimate the power of a wind turbine by means of the transfer function.
