Question

An electric power utility decides to add 50 MW of wind generation to its system. If the individual units are rated at 2 MW in a 12 m/s wind at standard conditions and have power coefficient of 0.35, mechanical and electrical efficiencies of 0.92 and 0.95. (i) Calculate the rotor swept area and rotor diameter. (ii) If the turbine is required to deliver rated power at 20 rpm and the generator rated speed is 1500 rpm, calculate the average torque at low speed and high speed shaft?

Answer 1

Answer:

an electric power utility decided to add 50mb of one generation to its system if the individual units are rated at to MW in 12 minutes for second wind at Standard conditions and have power to coefficient of 0.35 mechanical and electrical efficiency is of 0.91 0.95 I don't know the answer
