Question
A three phase 300km long line has a total series impedance of 200/90° ohms per phase and
a total shunt admittance of 0.0013290° Siemens per phase to neutral. If the sending end
voltage is 220kV and if the line supplies a loaf of 60MW at 0.8pf lagging, determine the
receiving end voltage and current.
Transcribed Image Text:A three phase 300km long line has a total series impedance of 200/90° ohms per phase and a total shunt admittance of 0.0013290° Siemens per phase to neutral. If the sending end voltage is 220kV and if the line supplies a loaf of 60MW at 0.8pf lagging, determine the receiving end voltage and current.
A transmission line has the following constants and supplies a load of 50MW at 110kV and
0.8pf lagging:
-
A = D = 0.96/1° B = 100/80° ohms per phase. Using power circle diagram, find the sending
end voltage and regulation.
