An interconnector cable having a reactance of 6 Ω links generating stations 1 and 2 as shown in figure. The desired voltage profile is |V1| = |V2| = 22 kV. The loads at two bus bars are 40 MW at 0.8 lagging power factor and 20 MW at 0.6 lagging power factor respectively. The station loads are equalized by the flow power in the cable. Estimate the torque angle and the station power factors.
