Wind analysis for wind power : Part I

open access: hybridMAUSAM, 1981
The paper contains the frequency distribution of hourly values of winds of Baroda in south Gujarat in the four ranges, viz., light, moderate, strong and very strong with the objective of utilisation of energy from winds for the windmills. A comparison has also been made with the results of similar studies made earlier in respect of Ahmedabad in north ...
