EEEN71345 Power System Dynamics & Quality of Supply (Dynamics) 15 Full year Postgraduate Taught Level 7 Jelena Ponocko Unit coordinator Department of Electrical & Electronic Engineering 1 FHEQ level (Framework for Higher Education Qualifications) ' Masters/Integrated Masters P4 ' European Credit Transfer & Accumulation System Rating : 7.5 <div> This unit aims to introduce students to basics of power system dynamics and quality of electricity supply issues and to discuss most widely used and recommended methodologies for enhancement of power system stability and mitigation techniques to overcome problems associated with quality of electricity supply.</div>  <div> (1) Power System Dynamics(i) The dynamic characteristics and control requirements of power systems are introduced. Consideration is given to the dynamic modelling of major power system components and controls including power system loads, excitation systems and governors.(ii) The modelling and control requirements will be discussed for small and large   disturbances studies and voltage stability studies. Methodologies, tools and techniques for performing these types of studies will be introduced. (iii)  The methodologies for enhancement of power system stability and tuning of power system controllers will be discussed.(2) Quality Of Supply(i) Introduction to Quality of Supply: Essential terms and definitions, importance and relevance, types of studies. Voltage variations in power system over and under voltages   voltage flicker and voltage transients. (ii) Voltage sags: definition, characteristics and causes, propagation and representation, consequences of voltage sags.(iii) Harmonics: Definition, propagation, sources and consequences and harmonic filter design.(iv) Assessment of financial losses due to power quality disturbances and recommended mitigation practise to solve quality of supply problems.(3) Reliability(i) Introduction to Reliability: Essential parameters, indicators and functions for non-reparable and reparable systems. State-space representation, Markov’s model, network models: series-parallel connection, state enumeration, Monte Carlo simulation.(ii) Generation systems: basic methods, operating reserve, interconnected systems.(iii) Composite generation and transmission systems: enumeration technique and Monte Carlo simulation.(iv) Distribution systems: radial networks, analytical techniques.  </div>   <div> This unit aims to introduce students to basics of power system dynamics and quality of electricity supply issues and to discuss most widely used and recommended methodologies for enhancement of power system stability and mitigation techniques to overcome problems associated with quality of electricity supply.</div>  <div> ILO1: Model power system components such as synchronous machines, transformers and transmission lines.ILO2: Evaluate the small-disturbance stability and large-disturbance (transient) stability of a power system.ILO3: Use software tools to analyse the large-disturbance behaviour of a power system.ILO4: Apply appropriate measures to improve power system stability.ILO5: Analyse power system voltage sags and harmonics.ILO6: Apply appropriate techniques to mitigate the impact of power system voltage sags and harmonics.ILO7: Assess the reliability of a power system.ILO8: Calculate the reliability cost for a power system.</div>  <div>  </div> <div> This unit is delivered entirely via part-time distance learning. The unit runs for 10 weeks, with a total of 150h of student work. It is split into 10 sections, while these map neatly onto the 10 weeks, students have flexibility to progress through the unit at a pace that fits with their other priorities. There are some fixed events, such as coursework deadlines, exams, and weekly tutorials but much of the course can be done at a pace that fits the student. Each section consists of:- An overview of the material, presenting the current learning objectives.- Explanatory material (~5h of student activity/section) in the form of video lectures, papers/articles, the course text, and links to further resources.- Exercises (~4h/section). These are formative, with feedback given in the tutorial.- Tutorial (~2h/every two weeks). Student will video conference with their tutor in groups of 6-10 to discuss and give/receive feedback. In addition to the planned activities there is also private study (~50h for the unit) consisting of:- Revision- Coursework- Further practice- Independent/further study</div><div>  </div> 1 Written exam 80% 3 Report 20% <table border="1" cellpadding="0" cellspacing="0" width="536"> <tbody> <tr> <td style="width:291px;"> Assessment task</td> <td style="width:151px;"> How and when feedback is provided</td> </tr> <tr> <td style="width:291px;"> - Written exam- Coursework</td> <td style="width:151px;"> Marked transcriptWritten comments</td> </tr> </tbody></table>  Elec Power Systems Eng (DL) Elec Power Systems Eng (DL) PGDT Dissertation Mandatory N 0 0 150
