Hello, so this is for part a.
00:01
The first thing we need to do is to find the per unit voltage.
00:05
So we have v subpu is equal to the actual v over the base of v, and that's equal to 117 ,300 over 115 ,000, and that is equal to 1 .02pu.
00:23
Now, the second step is the current in per unit.
00:29
So to calculate apparent power s using real power and power factor, we use s is equal to p over pf, which is equal to 95 over 0 .95, which is 100 mva.
00:42
So the apparent power in per unit, spu, is equal to 100 mva over 100 mva, which is just equal to 1 .0 p u.
00:58
Now, the next step is to use the per unit power formula.
01:02
So spu is equal to vpu times ipu, which is equal to ipu equals to spu over vpu, which is 1 .0 over 1 .02, which is equal to approximately 0 .904 p.
