1. Given the power system per-unit parameters and oneline diagram shown below,

Generator: H=2.5, Xd'=0.25, PG=0.7, terminal |V| = 1.02

Transformer: X=0.08

Line 1-2: R12=0, X12=0.15

Line 1-3: R13=0, X13-0.15

Line 2-3: R23=0, X23-0.15

determine:

(a) the reactive power output of the generator,

(b) the generator internal voltage, and

(c) an equation for the electrical power delivered by the generator as a function of its power

angle δ.
