Course description and aims

This course focuses on transmission technology of electric power, on which modern society heavily depends. Topics include equivalent circuit for a power system component, per-unit system, power circular diagram, fault analysis, and angle stability of a power system.

Student learning outcomes

At the end of this course, students will be able to:
1) Understand how electric power is delivered through a power system;
2) Construct the corresponding equivalent circuits to power systems;
3) Calculate imbalanced voltage, current, and/or impedance in power systems under fault conditions;
4) Obtain the voltage stability in transmission/distribution systems and the steady-state stability of generators.

Keywords

power system, three-phase circuit, active and reactive power, transmission line, power transformer, synchronous generator, equivalent circuit of a power system component, per-unit system, voltage control, fault analysis, symmetrical components, angle stability, protection relay, power distribution

Competencies that will be developed

Specialist skills Intercultural skills Communication skills ✔ Critical thinking skills Practical and/or problem-solving skills
✔ Applied specialist skills on EEE

Class flow

1) Lectures are given based on the materials distributed through T2Schola. Students are required to make preparation and review with the materials.
2) Quizzes are given during lectures to check understanding.
3) Submit the assignment at the end of the lecture by the specified date.
