Two three-phase generating power stations, A and B, work at 97 kV and deliver power to their respective consumers as follows: Power station A delivers 900 MVA to its consumers at a power factor of 0.766 lagging. Power station B delivers 600 MVA to its consumers at a power factor of 0.819 lagging. An interconnector with an impedance of (1.5 + j5.6) Ω per line is connected between A and B. The voltage at power station A is advanced with an angle of 9° with respect to the voltage at power station B. Use the complex power method and do the following calculations. Determine the total active power delivered or received by Power station A (Pi) in MW Determine the total reactive power delivered or received by Power station A (Qi) in MVAr Determine the total active power delivered or received by Power station B (Pj) in MW.
