Two power stations, A and B, are joined with an inter-connector having an impedance of
(2.1+j6) Ω/line. They are synchronized to work at 101.4 kV. The voltage at power station A is
advanced with an angle of 11° with respect to the voltage at power station B. They deliver
power to their separate consumers as follow:
Power station A: 400 MVA at a power factor of 0.92 lagging
Power station B: 350 MVA at a power factor of 0.866 lagging
instructions:round off to 2 decimal places
1.Determine the current within the interconnector (kA) and Determine the reactive power received by power station A (MVar)
2.Determine the active power received by power station B (MW)
3.Determine the active power loss within the interconnector (MW)
4.Determine the real power load of power station B (MW) and Determine the final loading of power station A (MVA)
5.Determine the final loading of power station B if its reactive power load is controlled to be reduced by 10%.
