Aims

This unit aims to:

Introduce students to power system dynamics and stability and develop an awareness of the reasons for changes in power system dynamic behaviour from the proliferation of converter interfaced technologies. Revise and build on control systems analysis for electrical/mechanical systems and power networks. The unit develops models for use in system studies and integration studies of renewables. These include machines, power electronic converters, other actuators, control mechanisms and electrical and thermal considerations. The unit will also revise techniques for dynamic analysis of faulted power systems and apply these to larger networks to evaluate post-fault system performance. 

 

Learning outcomes

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

ILO 1 Formulate, judge and explain basic principles of power system dynamics and causes of it in modern power systems 

ILO 2 Formulate the explain the reasons for the changes in system dynamic behaviour that will be caused by proliferation of low carbon technologies; Categorize and compare subdivisions of power system dynamic and stability phenomena. 

ILO 3 Derive models of power system components such as, synchronous and renewable generation, storage and demand technologies and associated controls, as well as transformers, converts, AC and HVDC transmission lines and most widely used FACTS devices for transient studies; Evaluate, analyse and compare their behaviours. 

ILO 4 Evaluate and analyse different aspects of power system stability including rotor angle stability, voltage stability, frequency stability, resonance stability and converter driven stability. 

ILO 5 Design the software models, apply the software tools to simulate and analyse different aspects of power system dynamic behaviour and stability 

ILO 6 Design and evaluate appropriate measures to improve or ensure power system stability; Develop and analyse the procedures for the tuning of power system controllers.
