find the sending end voltage and current, Electrical Engineering

Assignment Help:

A 3-phase transmission line is 200km long. The line has a per phase series impedance of 0.25+j0.45 Φ/km and shunt admittance of j7.2ΦS/km. The line delivers 250MVA, at 0.6 lagging power factor and 120V to a 3-phase load.

a) Determine ABCD parameters of the line.

b) Find the sending end voltage, sending end current, voltage regulation and the efficiency of the line.

c) Determine the capacitance per-phase of the Y-connected capacitors to adjust the power factor of the load to unity and calculate the voltage regulation and the line efficiency in this case.
