Problem a. (i) Sketch the ideal power curve of the turbine with the following characteristics:
• rated speed is 14 m/s
⚫rated power is 1.25 MW
⚫ cut-in speed is 5 m/s
⚫furling or cut-out speed is 20 m/s
(ii) Given part (i), calculate the energy produced in one day if the wind blows
continuously between 15 and 20 m/s all day
(iii) Can the energy produced in one year be determined if you are told that the
average wind speed is 14 m/s? Explain why.
Problem b. Suppose an anemometer mounted at a height of 10 m with a 20-m/s average wind
speed
(i) Estimate the average wind power at a height of 10 m, assuming Rayleigh
statistics and under the following weather conditions
• 15°C
(ii) Suppose a 1300-kW wind turbine with 60-m rotor diameter is located in those
winds with speed computed in the first condition of part (i). Determine the annual
energy production with a 30% wind turbine efficiency
(iii) Evaluate the wind turbine capacity factor
