V1 and V2 are wind speed values from the wind resource data file. This assumes that the file contains wind speed data at two or more hub heights.
For example, if the turbine height is 110 m, and the file contains wind speed columns for 100 m and 125 m, then V1 = wind speed at 100 m and V2 = wind speed at 125 m. P(V1) is the power in kW from the power curve at V1, and P(V2) is the power in kW from the power curve at V2.
Sir honestly I did not get you. I am confused, doing the reverse math since yesterday and didn't get the right of these three equations. I need ur help in detail.
Can u pls do the manual (handwritten calculations for 2-3 steps pls)? I have attached an excel sheet, screenshots and manual to see the formula! pls favour me and do the hand calculation and let me understand pls.
How P(V1) is the power (in kW) from the power-curve at 100m? (at 100m, really? we know that cut-off speed is 25m/sec)! weather file (with name SAME) is attached.
