ANALYSIS OF WIND CHARACTERISTIC PARAMETERS WITH A VIEW TO THE IMPLEMENTATION OF A 20MW WIND FARM in the DIANA Region

Environmental engineering

The use of renewable energy is one of the best solutions to the challenge of climate change. Madagascar demonstrates remarkable wind potential, especially in the northern part of the country. The purpose of this research is to locate a site favorable to the establishment of a large-scale wind power plant. A clearly detailed comparative statistical analysis of the two windiest communes in the two regions, Sofia and Diana, was carried out. The results showed that the municipality of Andranovondronina is suitable for the installation of the power plant: the wind frequency roses, the power density roses as well as the analysis of the turbulence, of the wind shear profile, show that the energy production is much higher than that of Amparihy. The wind potential is exceptional there and deserves to be exploited. At a height of 80m, the power density rose of Andranovondronina displays a density of around 1300W / m2 in the SE direction, 1130W / m2 in the SSE, and 825W / m2 in the ESE, against a value almost zero in sector N. 54% of the total wind energy comes from the SE sector, 35% comes from the ESE wind. Thus, southerly winds (SSE to S) averaging 11.5m / s occur 69% of the time and would develop 89% of the predicted power. The occurrence of wind in the North axis is almost low, the turbines would be oriented so that they are facing the wind, to be able to capture the maximum kinetic energy.
