QUESTION 4 [25 MARKS] As an electrical power system engineer, you must deal with the representations and performances of transmission line under normal operating conditions. Your manager Mr. Richard gives you a task i.e., to analyzes the performances of a three-phase transmission line that has the following parameters: • Transmission line length = 300 km • Positive sequence series impedance of z=0.0267 + j0.692/km • Positive-sequence shunt admittance, y=j5.333x10 S/km. • At full load condition, the line delivers PR-2500 MW, 0.9 power factor lagging at 132 kV line voltage to the receiving end load. Mr. Richard has explained about transmission line representations, ABCD parameters, currents, and voltages as a guide for you to do the analyses. Based on your fundamental knowledge, please evaluates the performances of the transmission line. Finally, please conclude that the performance of the transmission line is good, weak or poor. (*You may use any methods or techniques to complete the task) [25 Marks] [CO2, PO2, C4]
