Assoc. Prof. Dr. A. Jonaitis, Department of Electrical Power Systems

About the course:

The problem of dynamics and stability of power systems cover the basic propositions of

synchronous machine theory and principles of application, nature of oscillations in power

systems, dynamic characteristics of power loads and synchronous machines excitation

systems and, structure of power system dynamic model. PhD students will be able to create

mathematical models of the main elements of power system, know the main principles of

small-signal and transient stability investigation, understand the influence of control

automatics and protection on power system stability and be able to evaluate boundaries of

small-signal and transient stability.

Aim of the course:

To take knowledge on modern power systems dynamics investigation principles,

mathematical models composition possibilities and analyse of investigation results.

The specific aims are to deepen knowledge in power system elements mathematical models

formation, to teach of applying these models for power system dynamics and stability

investigation.

Target group:

For students having fundaments of power systems and power systems automation. The

course would broaden their knowledge in the sphere of power systems dynamic, stability

and control.

Course format, ECTS credits:

Full course sustains 22 hours of lectures and practical job, and 22 hours of individual work. An

individual work covers modelling of synchronous generators, excitation systems and speed

governors and peculiarities of small signal and transient stability analysis of power system.

Final exam (written) from all parts of course. The evaluation is on a pass/fail basis (graduation

on the Lithuanian 10-scale may be obtained if necessary).

Study load: 6 ECTS credits.
