A part of the power system is represented by the one-line diagram shown below. The system supplies a load of 40 MW at 66 kV with a power factor of 0.8 leading. Use the per unit method to find the following parameters, given that the base values in the Tranmission Line zone are 100 MVA and 130 kV. 100 MVA 275/130 kV X=0.1j p.u. Zn=3.48j 2 th 50 MVA 130/66 kV X=0.04j p.u. a) Find Zbase and Ibase in each zone. b) Plot the equivelent single phase system in per unit labeling all the components with their values. c) Find the source voltage Vg in V. d) Find the power injected to the system from the power station side in MVA. e) Find the efficincy of the system.
