Scenario: In your role of a project engineer you have been requested to produce a report consisting of
sections A and B.
Report Title: Power Systems
Name:
SID:
Section A: Power Systems
60 %
This section is based on methods deployed in order to reduce the undesirable effects in power systems
Requirements:
i. Power quality, research this field of power systems to explain how poor power quality
affects power systems operation. Include in your answer data relating to power system
quality along with analytical comment. Complete this section of your report by coverage of
methods used to improve power quality. Expected: Background research, analytical
comment.
ii. A power system supplying a steady power of 100 MW via a radial feeder is found to be
occasionally prone to a Y MW power demand transient surge of XX millisecond duration.
Making any assumptions as necessary design an inertial mass unit capable of supply the
transient. Expected: outline design, calculations and discussion of operation of the inertial
mass system. Please note XX is the first 2 digits of your SID and Y is the 3 digit of your SID (if
this is zero (0) add 1).
iii. Explain how power systems stability can be assessed e.g. criteria, then extend to show how
one off these criteria can be implemented via digital computation. Expected: theory, digital
application, algorithms and examples.
Section B: HVDC Modelling
40 %
Reference ABB Project Dogger Bank – Connecting the world’s largest offshore wind farm to UK grid
https://www.youtube.com/watch?v=RYG4rUHJeiY&feature=emb_logo
Review the above ABB media link, then:
i. Produce a suitable schematic diagram of an HVDC system that could be implemented to
allow power transfer from the windfarm to UK giving specific details major system
component function and function.

Important Please Read these Notes:

ii. Discuss HVDC converters types, operation to include harmonic generation.
iii. Power flow, discuss how power can be increased or decreased across a HVDC
interconnector.
iv. Cable and connections, discuss cable rating, cable construction to include materials and
other features of the cable, identify factors that would influence routing of the cable and a
likely connection on land for the system.

1. This report must be compiled at professional level i.e. all diagrams produced should be drafted
via a drawing package all text compiled via a word processor. All external sources of information
must be cited as must diagrams, data and charts.
2. You are expected to use the Coventry University APA reference style see: https://
libguides.coventry.ac.uk/apa. For support and advice on this students can contact Centre for
Academic Writing (CAW).
3. Please notify your registry course support team and module leader for disability support.
4. Any student requiring an extension or deferral should follow the university process as outlined
here.
5. The University cannot take responsibility for any coursework lost or corrupted on disks, laptops
or personal computer. Students should therefore regularly back-up any work and are advised to
save it on the University system.
6. If there are technical or performance issues that prevent students submitting coursework
through the online coursework submission system on the day of a coursework deadline, an
appropriate extension to the coursework submission deadline will be agreed. This extension will
normally be 24 hours or the next working day if the deadline falls on a Friday or over the
weekend period. This will be communicated via your Module Leader.
7. Assignments that are more than 10% over the word limit which is 4000words will result in a
deduction of 10% of the mark i.e. a mark of 60% will lead to a reduction of 6% to 54%. The word
limit includes quotations, but excludes the bibliography, reference list and tables.
8. You are encouraged to check the originality of your work by using the draft Turnitin links on your
Moodle Web.
9. Collusion between students (where sections of your work are similar to the work submitted by
other students in this or previous module cohorts) is taken extremely seriously and will be
reported to the academic conduct panel. This applies to both courseworks and exam answers.
10. A marked difference between your writing style, knowledge and skill level demonstrated in class
discussion, any test conditions and that demonstrated in a coursework assignment may result in
you having to undertake a Viva Voce in order to prove the coursework assignment is entirely your
own work.
11. If you make use of the services of a proof reader in your work you must keep your original version
and make it available as a demonstration of your written efforts.
12. You must not submit work for assessment that you have already submitted (partially or in full),
either for your current course or for another qualification of this university, unless this is
specifically provided for in your assignment brief or specific course or module information. Where
earlier work by you is citable, ie. it has already been published/submitted, you must reference it
clearly. Identical pieces of work submitted concurrently will also be considered to be selfplagiarism.

GRADE	ANSWER RELEVANCE	ARGUMENT & COHERENCE	EVIDENCE	SUMMARY
First ≥70	Innovative response, answers the question fully, addressing the learning objectives of the assessment task. Evidence of critical analysis, synthesis and evaluation.	A clear, consistent in-depth critical and evaluative argument, displaying the ability to develop original ideas from a range of sources. Engagement with theoretical and conceptual analysis.	Wide range of appropriately supporting evidence provided, going beyond the recommended texts. Correctly referenced.	An outstanding, well-structured and appropriately referenced answer, demonstrating a high degree of understanding and critical analytic skills.
Upper Second 60-69	A very good attempt to address the objectives of the assessment task with an emphasis on those elements requiring critical review.	A generally clear line of critical and evaluative argument is presented. Relationships between statements and sections are easy to follow, and there is a sound, coherent structure.	A very good range of relevant sources is used in a largely consistent way as supporting evidence. There is use of some sources beyond recommended texts. Correctly referenced in the main.	The answer demonstrates a very good understanding of theories, concepts and issues, with evidence of reading beyond the recommended minimum. Well organised and clearly written.
Lower Second 50-59	Competently addresses objectives, but may contain errors or omissions and critical discussion of issues may be superficial or limited in places.	Some critical discussion, but the argument is not always convincing, and the work is descriptive in places, with over-reliance on the work of others.	A range of relevant sources is used, but the critical evaluation aspect is not fully presented. There is limited use of sources beyond the standard recommended materials. Referencing is not always correctly presented.	The answer demonstrates a good understanding of some relevant theories, concepts and issues, but there are some errors and irrelevant material included. The structure lacks clarity.
Third 40-49	Addresses most objectives of the assessment task, with some notable omissions. The structure is unclear in parts, and there is limited analysis.	The work is descriptive with minimal critical discussion and limited theoretical engagement.	A limited range of relevant sources used without appropriate presentation as supporting or conflicting evidence coupled with very limited critical analysis. Referencing has some errors.	Some understanding is demonstrated but is incomplete, and there is evidence of limited research on the topic. Poor structure and presentation, with few and/or poorly presented references.
Fail <40	Some deviation from the objectives of the assessment task. May not consistently address the assignment brief. At the lower end fails to answer the question set or address the learning outcomes. There is minimal evidence of analysis or evaluation.	Descriptive with no evidence of theoretical engagement, critical discussion or theoretical engagement. At the lower end displays a minimal level of understanding.	Very limited use and application of relevant sources as supporting evidence. At the lower end demonstrates a lack of real understanding. Poor presentation of references.	Whilst some relevant material is present, the level of understanding is poor with limited evidence of wider reading. Poor structure and poor presentation, including referencing. At the lower end there is evidence of a lack of comprehension, resulting in an assignment that is well below the required standard.
