Question
The ABCD parameters of a 200-km, 230-kV, 60-Hz three-phase line are
A = D= 0.968 0.32, B=97.32480 2 C=6.55x10 290 S
At full load the receiving-end current is equal to 6624-8° A, while the receiving-end voltage is equal to 220 kV (Line-to-Line). The
receiving-end voltage (Line-to-neutral) is considered as the reference phasor. Find
1. The sending-end voltage
Vs=
kV
2. The sending-end current,
Is =
3. The percent voltage regulation.
Vreg=
%
4. The reactive power delivered by the admittance of the transmission line at the receiving-end side
Qc=
Var
