BRIEF DESCRIPTION OF THE UNIT

(1) Power System Dynamics (24)

(i)  Introduction to the module and review of general dynamic characteristics and control requirements of power systems. (1 hour)

(ii)  Modelling of major power system components and controls for power system dynamic studies including

- synchronous generator operation and  dynamic models (3 hours)

This unit aims to:

On successful completion of the course, a student will be able to:

ILO 1: Model power system components such as synchronous machines, exciters and governors, transformers, transmission lines and loads.

ILO 2: Explain network resonances, harmonics, harmonic study and filter design, and calculate relatively simple problems related to harmonics and filter design.

ILO 3: Use software tools to analyse the large-disturbance behaviour of a power system.

ILO 4: Explain basic principles of power system dynamics and causes of it.

ILO 5: Explain, evaluate and calculate reliability of generation and distribution systems for system planning, as well as operational reliability of generation systems.

ILO 6: Explain fundamental concepts of non-repairable and reparable components/ systems, and solve basic theoretical problems.

ILO 7: Explain and calculate reliability of transmission networks for system planning, and reproduce different calculation methodologies.

ILO 8: Calculate and apply appropriate measures to improve or insure power system small and large disturbance stability and tune power system damping controllers.

ILO 9: Evaluate the small-disturbance stability and large-disturbance (transient) stability of a power system.

ILO 10: Explain voltage variations and voltage sags, name mitigation measures to improve QoS, and solve relatively simple problems related to voltage sags.

The unit involved lectures, tutorials, one 6-hour laboratory, several tutorial sessions lead by PDRAs. Lectures were supported with Power Point presentations. All relevant material, including solved examples, timetable, detailed reading list with instructions, exam feedback from the past year  and laboratory instructions was available on the balckboard in electronic format. Additional paper copies of the material were distributed during the first lecture.
