Design Procedure
Draw the oneline shown on the next page using ETAP
The length of all the cables is 500 ft. Chose a cable sized 750 kcmil at 15 kV rated voltage. Use the ETAP library feature to select the cables.
Short circuit rating of the source is 100 MVA and the source impedance is 0.42 Ω.
Analyze the oneline using load ow analysis.
Observe and correct (a) the bus undervoltages (b) cable overloads.
The bus undervoltage should be no lower than 97% of the nominal voltage.
Assignment Submission
Submit a printout of the final successful oneline diagram showing the power flows and bus voltage percentages generated by ETAP
Submit the final complete load ow report generated by ETAP.
The next part of the assignment consists of studying the impact of PV penetration on the bus voltages.
