Course description and aims
This course focuses on analysis of electric power systems and motor drive systems and on their applications. It includes the p-q theory in three-phase circuits, and the instantaneous active and reactive power defined by the theory, as well as d-q transformation for ac motors. In addition, it presents the so-called vector control or filed-oriented control for induction and synchronous motors.
Student learning outcomes
By the end of the course, students will be able to:
1) explain the similarity and difference on active and reactive power between single-phase and three-phase power systems.
2) apply the analysis method based on the "instantaneous reactive power theory" to fundamental analysis of electric machines and/or power systems.
3) apply the control method based on the "instantaneous reactive power theory" to basic control of electric machines and/or power systems.
4) derive the voltage and current equations for various electric machines and power devices.
5) understand the basis of instantaneous torque control methods for various ac motors and to implement the required controls.
Keywords
Active power, reactive power, power flow, ac motors, torque control.
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
The instructor will first present some contents, such as theories, analysis methods, applications, and so on. After that, students are requested to discuss the assigned topic based on the presented contents in the class.

Out-of-Class Study Time (Preparation and Review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook(s)
The lecture documents will be distributed through OCW/i.
Reference books, course materials, etc.
The related documents, e.g. technical papers, will be introduced during the lecture.
