Q)How much is efficiency of Wind Turbines?Ans) 40 %
Q) How long it takes to plan and buid a 5 MW wind farm?
Ans) 9 Months
Q) Wind power varies as wind speed?
Ans) Cube of v
Q) Wind power is directly proportional to
Ans) Height of blade.
Q) What are three factors behing wind turbine design?
Ans)
- Efficient airfoil design ( can increase 30 % energy capture)
- Rotor Efficiency( Better hub attachments allow for flex. rotors)
- Design of control devices
Q) Are 2 blade rotors better?
Ans) Yes , but they should be flexible enough for wind gusts.
Q)What is big deal about WT generator?
Ans) Design of generator which can respond to changes in Wind is a challenge.
Q)What is rotor speed?
Ans) rotor @ 60 rpm, generator @ 1800 rpm.
Q) What are 4 functions of turbine control?
Ans)
- To slow/stop the rotor.
- To prevent wind gusts from suddenly producing high power.
- To prevent turbine from vibrating.
- To mitigate damage from turbulent winds.
All above are achived by computer/microprocessor control.
Q) How much is cost of Winf farm?
Ans) Rs 50 million per MW
Q) Do you have any idea about wind power density at 50 m in India?
Ans) TN/Kerala/Karnataka about 350 to 450 W/sq. m

Dear Mr.Raj,
I am Santosh Reddy Resu from Hyderabad,INDIA but Currently pursuing Master's in Electrical Engineering from Oklahoma State University,U.S.A . Due to the interest in Wind Energy I would like to visit one of the wind farms in India may be for a week in July,2012 and want to know the structure of its working and how do they deal with it in various scenarios. Since I am new to this such as contacting officials and knowing any information I would be very help full if you can give me any ideas regarding how to approach any wind farm officials and some information regarding any thing important I might have missed.
Regards,
Santosh Reddy Resu
Sorry i saw the comment a bit late.Visiting wind farm is not difficult as most are privately owned. Hope you were successful in the trip.
