Question 8: Using a typical frequency response illustrate the different hierarchies of frequency control in large-scale power system. Discuss and illustrate using a numerical example why governors using speed droop or speed regulation cannot alone restore the power system frequency to the pre-disturbance level. Question 9: An isolated 50 Hz synchronous generator is rated at 15 MW which is also the maximum continuous power limit of its prime mover. It is equipped with a speed governor with 5% droop. Initially,...

A three-phase synchronous generator with rated data VM = 20 kV, SM = 100 MVA, n = 500 rpm is driven by a turbine that can provide a maximum of 1.6 MNm. Synchronous reactance, XS = 3Ω / phase. The armature resistance (Ra ) is neglected. In open circuit mode (P = 0), an excitation current of 300 A is required to obtain rated voltage (VM ). The machine should be phased into a strong grid, 3x20 kV, 50 Hz....
