Question

Two power stations, A and B, are synchronized at 88 kV. They are interconnected by a transmission line with an inductive reactance of 5.7 Ω and resistance of 1.3 Ω. The voltage of power station A is advanced with an angle of 7.8 degrees with respect to the voltage of power station B. The loading of power station B has a real power of 312.31 MW. The respective loads of the two power stations are as follows:

Power station A: 700 MVA at a power factor of 0.819 lagging.

Power station B: The reactive power consumed by the load is 412 Mvar.
