Two power system areas operating at a nominal frequency of 60 Hz are connected with a tie line, and have the following characteristics: Area 1: R1 = 0.01 pu and D1 = 0.8 pu on a base of 1200 MVA Area 2: R2 = 0.02 pu and D2 = 1 pu on a base of 600 MVA The power flow direction on the tie line is from Area 1 to Area 2. Using a common base of 1000 MVA, what is the change in prime mover power (in MW) in Area 2 (APmech2) for a load increase of 125 MW in Area 1?

Question
Two power system areas operating at a nominal frequency of 60 Hz are connected with a tie line, and have the following
characteristics:
Area 1: R1 = 0.01 pu and D1 = 0.8 pu on a base of 1200 MVA
Area 2: R2 = 0.02 pu and D2 = 1 pu on a base of 600 MVA
The power flow direction on the tie line is from Area 1 to Area 2.
Using a common base of 1000 MVA, what is the change in prime mover power (in MW) in Area 2 (APmech2) for a load
increase of 125 MW in Area 1?
