Course content

1. Steady state and transient system analysis using simplified models for the synchronous machine. 2. Power-frequency control and voltage control using more detailed models of turbines, generators and network. Emphasis on modelling of synchronous machines and hydro turbines including penstock and governors (controllers). Power system damping and application of FACTS components. Secondary control: active reserves and load following control. Teaching in class, exercises and project work. A group project work running through most of the semester is a major part of the home work. MATLAB and SIMPOW are used as tools for modelling and simulation of various aspects of power system stability phenomena. The project is being graded and is given 25% weight at the final exam.

Learning outcome

The course aims to give basic knowledge about the dynamic mechanisms behind angle stability problems in electric power systems, including physical phenomena, modelling issues and simulations.

Learning methods and activities

Lectures. Compulsory exercises and computer simulations. Compulsory project work. The final evaluation will be based on a written examination (counting 75%) and a project (counting 25%) based on % fulfillment. Final grading will be from A to F. The course is given in English. If there is a re-sit examination, the examination form may change from written to oral.
