The paper presents the retrospective analysis of 25 years of wind speeds and power prediction using numerical whether prediction model at a complex terrain site in Kerala. The simulated data from the model has been validated using on-site/observed data for the same location obtained from C-WET mast. The model has been fine tuned so as to bring it closer to the observed value by using variance and bias. It is felt that by blending the best of direct onsite measurements with the atmospheric model techniques will give a reliable, credible and comprehensive understanding of the wind resources which will help in maximizing the performances of the wind farms developed in complex terrains with reference to the Indian context thus mitigating the risk of underperformance.Keywords

In the context of achieving a national set target of 60 GW by 2022, a study was carried out in Kayathar, Tuticorin district, Tamil Nadu, India on noise propagation from wind turbines. Acoustic and non-acoustic parameters were measured according to IEC 61400-11 at wind speeds of 4-13 and 0.7-8.6 m/s. The onsite measurements were compared with ISO 9613-2; this showed a difference of ± 5 dB(A) for every increment in the distance. An equation was derived to obtain sound pressure level (dB(A)) at the base of the tower for wind turbines at varying distance of measurement.Keywords
