The purpose of this graduate class is to achieve analysis of electric power systems and ac motor drives.
In addition, this class includes applications of the theories to electric power utility and industry.
Note that this graduate class is based on the following two undergraduate classes: Electrical Machinery and Power Electronics.
1.Analytical methods and basic theories
2.Active and reactive powers in single-phase circuits
3.Instantaneous power theory in three-phase circuits
3-1.Definition of the instantaneous active reactive powers and their physical meanings 1.
3-2.Applications of the theory to power electronics equipment 2.
4-1.Absolute transformation and three-to-two phase transformation 1.
4-2.dq transformation 2.
5.Voltage and current equation and instantaneous torque of ac machines
6.Vector control of induction machines
7.Vector control of synchronous machines
A copy of materials necessary for this class will be given to each student.
This class requires knowledge of electric machines and power electronics in undergraduate levels
Evaluation will be based on the term-end examination.
The instantaneous power theory in three-phase circuits and the so-called dq transformation for ac machines are indispensable for all of graduate students who are majoring in power electronics and power engineering. This course gives you comprehensive theory and practice related to analysis of electric power systems and ac motor drives.
