Syllabus:

Power Line Representation - Single Line Diagram, Per Unit System for single phase circuits, Per Unit System for three phase circuits. Transmission Line Representation - AC vs DC transmission, Standard Transmission Voltages, Series Impedance Calculation (resistance, inductances and capacitances), Short - Long line models (A, B, C, D constants), Efficiency and Voltage regulations, Series and Shunt Compensations. Power Flow Calculations - Review of Real, Reactive and Apparent Power, Gauss-Seidel Load Flow Method, Decoupled Load Flow Method, Contingency calculations, DC Load Flow. Three Phase Fault Calculations - Symmetrical fault, Symmetrical components, Positive, Negative and Zero sequence equivilent circuits, Unsymmetrical Faults (L-G, L-L-G, L-L faults),Circuit Breaker Ratings.

Unit Outcomes:

On successful completion of this unit students will have received an overview of the bulk power system and gained an understanding of the per unit calculations, the single line representation of the power system and the transmission line parameter calculations. They will have attained the ability to model a threephase power system, calculate voltages, angles and MVA flows in a power system and three phase symmetrical and unsymmetrical faults. They will have gained an awareness of the importance of power flow calculations and of the simplification techniques in calculations of power flows and an appreciation of power quality and harmonics.
