A three phase double circuit O.H.T.L 230 mile,130 KV, 60 Hz has a flat configuration (23.8 ft=7.25 m ), ROOK (GMR is 0.0327 ft, and the outside diameter 0.977 inch) is connected to 50 MW load at 0.85 lagging PF. Each phase in the double circuit has a double bundle with a spacing d equals 20 cm between each conductor, r= 0.160 Ω/mile. Find:
Vs, Is, PFs.
Voltage regulation, efficiency
β and the velocity.
The equivalent π parameters(lumped).
new values of ABCD constants if 65% series compensation is employed.
Voltage regulation of line when shunt inductor is connected at received end during no load conditions if reactor compensates for 70% of total shunt admittance.
ε=8.85×〖10〗^(-12)
1 mile = 1609 m
1 Foot = 0.3048 Meters
1 Inch = 0.0254 Meters
