Control and simulation principles of drives and converter systems

The generalised machine theory is the subject of modeling the electric machines and drives as well as the power system. It needs understanding of e.g. electrical machines in space phasor models, axes transformations and dynamic modeling. The theory given on this course will be applied on the machines, drives and power electronics converter modelling and control. Instantaneous active and reactive power theories are taught and their applications are introduced.

Course contents

This course will cover following topics:

• The matrix equation of the basic rotating machines
• Reference frame theory
• Theory of symmetrical induction and synchronous machines
• The instantaneous power theories
• Reference frame theory used in the analysis and simulation of power systems and drives
• Basic voltage and current controllers for power electronics converters

Learning outcomes

After completing this course successfully, the student

• understands the latest development in electronics, machines and modern control theory,
• understands the machine models with power electronics,
• has developed their analytical abilities for understanding electrical machines dynamics,
• has a general approach for modeling of electromechanical devices,
• has an overview about simulation of drives in power systems as well as about the dynamics and control of grid-connected inverters.
