Objectives
The course aims to develop students’ interest in and knowledge and understanding of tools and methods for system stability, control and power system circuit interruption and switching over-voltages. The course addresses in depth stability and switching over-voltages.
Learning Outcomes:
Students will develop knowledge and understanding of:
- fundamental concepts, principles and mathematical theories used for stability problems
- fundamental concepts for the study of switching overvoltages.
They will acquire intellectual and practical skills to:
- develop appropriate models of scenario to study the stability problem
- develop appropriate models to study switching overvoltages.
