Review Questions-5
1. How Weibull Distribution is used for the selection of an appropriate wind turbine for a specific site?
2. What are the future prospects for wind energy development in India in particular and the world in
general?
3. Explain the frequency distribution of mean hourly wind speed for a year as Weibull distribution with
respect to range of values of its scale and shape parameters.
4. How is wind shear taken into account in WRA? What is one by seventh index?
5. What are the Wind Power Classes for major wind power producing states in India?
6. A wind machine with rated power, PeR = 1 MW has the rated wind speed, VR , of 7.5 m/s. It has cutin speed, VC , of 3 m/s and cut-off speed, VF , of 20 m/s. It is installed at a place with annual Weibull
parameters, K = 2.1, and C = 6 m/s. Find its capacity Factor, Annual average power output and
energy output.
{Hint: Use equation for estimating capacity factor, in terms of values of K, C, VC, VR, and VF}
