Two generators are supplying a load. Both the generators have a no-load frequency of61.5 Hz and the slope sp of 1 MW/HZ. If they are supplying a real load of 2.0 MW at 0.8 pflagging, what would be the system frequency and power sharing between two generators?What measures can be taken to make the frequency 60 HZ. If an additional 1.0 MW load isconnected to the existing one what would the system frequency be.

Comment Shard Q9: Salalah city is planning to install a 3.0 MW wind turbine. The turbine has a 112 m rotor diameter and the power/speed curve shown in Figure Q9. During the daytime hours (7am to 7pm) the wind speed is 12 m/s and the cost of electricity is $100/MWh. During the nighttime hours the cost of electricity is $50/MWh and the wind speed is 6 m/s. Assume that the air density is constant at 1.2 kg/m³. Determine the power output, wind power input, and efficiency of the turbine/generator during the daytime hours. Determine the power output, wind power input, and efficiency of the turbine/generator during the nighttime hours Calculate the daily revenue that the plant earns from selling electricity. 3,000 2,500 2,000 1,500 1.c00 s00 25 Outout kW)
