EEEN71316 Analysis of Electrical Power & Energy Conversion Systems (AEPECS) 15 Variable teaching patterns 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 revise and build on control systems analysis for electrical/mechanical systems and power networks.The unit develops models for use in system integration studies. These include power electronic converters, machines, other actuators, mechanisms and thermal considerations. Examples include industrial, automotive, aerospace and marine power-trains.The unit will also develop and formulate techniques and models of power networks for use in steady state analysis. Different method for power flow will be developed and used as a basis for quasi-steady state regulation and control of systems based on power imbalance. The unit will also revise techniques for analysis of faulted power systems and apply these to larger networks to evaluate system performance.  </div>  <div> Analysis and Control of Large Networks (10 hours):- 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. (3 lectures)- 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. (3 lectures)- Control of real and reactive power flows: effects of tap changers and quadrature boosters. (2 lectures)- Frequency regulation techniques in large power networks. (2 lectures) Analysis and Control of Power Electronics Systems (15 hours):- 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. Faults in Large Networks (5 hours):- 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. (2 lectures)- Asymmetrical fault calculations: Synthesis and connections of sequence networks; solution of sequence networks by standard circuit analysis techniques; transformation back to the phase domain.

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 (~3h 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.- 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 (~1h/week). Student will video conference with their tutor in groups of 6-8 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>  0 Other 100% <table border="1" cellpadding="0" cellspacing="0" width="640"> <tbody> <tr> <td style="width:291px;"> Assessment task</td> <td style="width:104px;"> Length</td> <td style="width:151px;"> How and when feedback is provided</td> <td style="width:95px;"> Weighting within unit (if relevant) </td> </tr> <tr> <td style="width:291px;">  CourseworkPeer-reportMaple TA online examMini-viva </td> <td style="width:104px;">  1 page*½ page2 x 1h20mins</td> <td style="width:151px;">  Written commentsTutorialMarked TranscriptRubric & comments</td> <td style="width:95px;">  20105020</td> </tr> </tbody></table>*The 1 page report is based upon a software model which also must be set up and submitted.
