Question:-
Consider two buses connected by an impedance of (0+j5)ohm. The bus 1 voltage is 100Ð30°V , and bus 2 voltage is 100Ð0°V. The real and reactive powers supplied by bus 1, respectively, are
Option (A)
1000W, 268VAr
Option (B)
–1000W, –134Var
Option(C)
276.9W, –56.7Var
Option(D)
–276.9W, 56.7Var
Correct Option:
(A)
Question Solution:
P = {(100 x 100) / 5} sin 30 = 1000; Q = {(100 x 100) / 5} cis30 – {(100 x 100) / 5} = - 268
