Q4) The three phase circuit seen in the following figure is derived by a three phase balanced
generator with the line-to-line voltage vRs(t) = 380V2 cos(2n50t) Volts, vsr(t) =
380V2 cos(2n50t – 120°), vrr(t) = 380/2 cos(2n50t + 120°). The transmission line
impedances and the load impedances are just multiples of the impedance Z = R + jwL with R=
k*19v3 /2 1 and L = k*19/200t H (k is given in Question-4 sheet of Parameters.xlsx). Find a) the
sinusoidal steady-state solution of the ig(t) current, and b) the total complex power consumed by
the three phase generator. Note: transform the load part from Delta to Y to include line loads and
then re-transform it to the Delta to do Delta-Delta analysis.
