3) Load Flow Calculations: For the following calculations use the following data: System Bases Power Base: Voltage Base: Transformer Ratings Power: Voltage Ratio: Reactance: b. c. 100 MVA 3.3kV 10 MVA 13.2kV/3.3kV 10% a. Calculate the impedance base of the system. Calculate the impedance of the transformer in per unit (in the system base) Calculate the impedance of a transmission line in per unit if the real impedance the line is 0.5+j2 d. If a load is connected with 2 MW and 1 MVAR what would the equivalent impedance be, in per unit, for short circuit studies?
