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 an equivalent circuit of a power system;
3) Understand transmission characteristics of a power system under normal and fault conditions

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 OCW-i. Students are required to make preparation and review with the materials.
2) Students must submit a report on exercise problems assigned in each class.
3) Solutions to the problems assigned in the previous class are explained at the beginning of each class.
