Problem 1 A 2.1-MW Sulon S97 wind turbine has a cut-in wind speed uc = 3.5 m/s, rated wind speed u, = 11 m/s and a furling wind speed of uf = 20 m/s. If this machine is located in Rayleigh winds with an average wind speed of 7 m/s, find the following: a) How many hours per year is the wind below the cut-in wind speed? b) How many hours per year will the turbine be shut down due to excessive winds? How many kWh/yr will be generated when the machine is running at rated power? c)
