Question

Al Kamil Power Company is an independent power generation company established to build, own and operate a 285 MW electricity generating station at Al Kamil in the Sharqiya Region of the Sultanate of Oman.The power station at Al Kamil has three generating units. Each unit incorporates a gas turbine and an electrical generator. One of the generators supplies 75 MW to an infinite bus bar, the steady state limit of the system being 135 MW. Will the generator remain in synchronism if the prime mover input is abruptly increased by 40 MW? Assume losses are zero. How you justify your response is correct for the given scenario?

Answer 1

I HAVE DONE COMPLETE ANALYSIS AND ATTACH MY NOTE.
