ECE 419 Power System AnalysisFall Semester, 2007

Catalog Data: Transmission systems analysis and design. Large scale network analysis using Newton-Raphson load flow. Unsymmetrical short-circuit studies. Detailed consideration of theswing equation and the equal-area criterion for power system stability studies.

Prerequisites: ECE 319. (3-3-4)

Enrollment: Elective course for CPE and EE majors.

Textbook: Hadi Saadat, Power System Analysis , Second Edition, McGraw Hill, 2002.

Coordinator: H. Shanechi, Senior Lecturer of ECE

Course objectives:After completing this course, the student should be able to do the following:1. Derive and calculate the resistance, inductance, and capacitance for single-phase and three-phase transmission

lines.2. Derive the models for short, medium, and long transmission lines and calculate the line performance indices.3. Apply Gauss-Seidel method, Newton-Raphson method, and Fast-Decoupled method to obtain a power flow

solutions of small power systems (2- or 3-bus systems)4. Describe the three-phase symmetrical fault and use Thevenins equivalent and Z-bus matrix to calculate the

three-phase faults applied to small power systems (2- or 3-bus systems).5. Apply the concept of the symmetrical components in the calculation of unsymmetrical faults (single-line-to-

ground, line-to-line, and line-to-line-to-ground faults).6. Describe the power swing equations for a single machine to infinite bus system and use them in transient

stability analysis.7. Derive the swing and power equations for a single machine connected to infinite bus system and use them in the

transient stability calculation. Use the Equal-Area Criterion in calculating the critical clearing time to clear afault and in determining whether the machine will remain stable following a disturbance such as three-phasefault or an increase in the machine mechanical power input.

8. Use Matlab in solving questions related to the above seven objectives.9. Apply PSS/E to perform transmission line modeling, power flow analysis, and fault analysis.
