EEEN71315 Analysis of Electrical Power & Energy Conversion Systems (AEPECS) 15 Full year Postgraduate Taught Level 7 Christos Zachariades 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 The unit aims to impart knowledge and skills for mathematical modelling as well as the techniques for steady-state and dynamic analysis of electric power transmission networks. It introduces the techniques required to analyse the power flow and fault performance of systems ranging in size from local islanded power systems to pan-country grids. <div> It also introduces the techniques required to analyse and understand the performance of the power electronic systems that are increasingly important in modern power systems such as HVDC. </div>   <div style="font-family: Arial, sans-serif; color: rgb(60,60,60)">   <div> Faults in Power Systems:- Symmetrical fault calculations: Modelling of networks under fault; solution using basic circuit analysis; the concept of short-circuit level and its factors of influence; faults in large networks.- Asymmetrical fault calculations: Synthesis and connections of sequence networks; solution of sequence networks by standard circuit analysis techniques; transformation back to the phase domain. Analysis and Control of Large Networks:- Formulation of the power flow problem from first principles: Rectangular and polar forms; numbers of equations and variables; Bus classification (PQ, PV, slack); matrix-vector formulation.- Solution techniques for the power flow problem: Newton-Raphson algorithms (basic principle in one-dimension; extension to the multi-dimensional case; load flow feasibility, convergence and ill-conditioning; exploitation of PQ decoupling), DC power flow.- Control of real and reactive power flows: effects of tap changers and quadrature boosters.- Frequency regulation techniques in large power networks. Analysis and Control of Power Electronics Systems:- Piece-wise-linear modelling and numerical techniques for time-domain solution. Circuit simulation. State-space averaging, and small-signal linearization. Transfer function models.- Lumped parameter modelling of transient and steady-state mechanical and thermal systems, application of state-variable systems.</div> </div>   <div style="font-family: Arial, sans-serif; color: rgb(60,60,60)">  The unit aims to impart knowledge and skills for mathematical modelling as well as the techniques for steady-state and dynamic analysis of electric power transmission networks.

The unit runs for 10 weeks, with a total of 150h of student work. There are some fixed events, such as coursework deadlines, exams, and 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 (~4h of student activity/section) in the form of video lectures, papers/articles, the course text, and links to further resources.- Worksheets (~3h/ section). These are formative. Final numerical answers are provided.- Discussion (~2h/ section). Students are encouraged to discuss the exercises and material in the forums where tutors will facilitate peer learning, providing feedback/input if necessary.- Formative Questionnaire. This is to gather students’ questions and highlight misconceptions ready for 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>    1 Written exam 70% 3 Report 20% 9 Set exercise 10%   <table border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td style="width: 177px"> Assessment task</td> <td style="width: 189px"> Length</td> <td style="width: 180px"> How and when feedback is provided</td> <td style="width: 95px"> Weighting within unit (if relevant)</td> </tr> <tr> <td style="width: 177px">  - Written exam- Coursework- Section Exercises </td> <td style="width: 189px">  2.5hBb quiz + 2 pages report*Bb quiz</td> <td style="width: 180px">  Marked transcriptBb + written commentsBb auto-marked + tutorial</td> <td style="width: 95px">  702010</td> </tr> </tbody> </table>  *The report is based upon a software model which also must be set up and submitted.
