Turbine Unit and Mechanical Output Generated
November 8th, 2022
An area of an interconnected 60 hz power system has three turbine generator units rated 100MVA, 200MVA, and 600MVA respectively. Regulation constants are given for each unit, with the load suddenly decreasing by 100MW. With assumptions made and a frequency response of beta = 165 p.u., calculate the MW decrease in mechanical output of each turbine, out of the four possible choices in the attached document.
