b) A power system has a total load of 1400 MW at 50 Hz, D = 1.2. A load of 50 MW is tripped, find the steady state frequency deviation if i) There is no speed control ii) The system has a spinning reserve of 250 MW with a regulation of 4% on this capacity. Due to governor dead band only 75% respond to the change in load. 5. a) Why is it necessary to have two control loops for ALFC.
