EGR9017 Assessment Coursework 1 Brief

Module learning outcomes

LO1: Able to draw upon a detailed knowledge and understanding of the fundamental principles and numerical techniques within the thermodynamics associated with sustainable power generation.

LO2: Able to make use of existing theories and principles of modelling and analysis, in order to improve machine performance.

LO3: Able to evaluate system requirements and formulate strategies for technology selection in the provision of sustainable energy systems.

LO6: Able to work as part of a team and plan and collectively manage time and resources in the execution of a task.

Description of assessment task

You are given 3 questions to answer and 1 labwork to perform.

In the labwork, you will investigate the power-factor correction of a single-phase induction motor. You will then perform calculations to verify your measurements and discuss applications. You should present your work in a readable form including calculations, written explanations, simulations, annotated diagrams and illustrations as appropriate.

Assessment submission instructions

All work should be submitted by the deadline stated as a single file in Word or PDF format to the module assessment link provided.

(In cases of technical issues please email your assessment to: sepssubmissions@lincoln.ac.uk by the deadline. Please include the module code and coursework title in the email subject.)

Please note that Onedrive links and zipped files will NOT be accepted.

Important Information on Dishonesty,  Plagiarism and AI Tools

University of Lincoln Regulations define plagiarism as ‘the passing off of another person’s thoughts, ideas, writings or images as one’s own…’. Examples of plagiarism include the unacknowledged use of another person’s material whether in original or summary form. Plagiarism also includes the copying of another student’s work’. Plagiarism is a serious offence and is treated by the University as a form of academic dishonesty. For more information on examples of Academic Offences, please see the Academic Offence Guidance.

The use of AI tools: Not Permitted (delete as appropriate)

Please note, if you use AI tools in the production of assessment work where it is not permitted, then it will be classed as an academic offence and treated by the University as a form of academic dishonesty.

Students are directed to the University Regulations for details of the procedures and penalties involved.

For further information, see www.plagiarism.org

Marking Criteria for Assessment

Questions 1-3 are each worth 20, 25 and 5 marks respectively.

The labwork is worth 50 marks.

Please note that all work is assessed according to the University of  Lincoln Management of Assessment Policy and that marks awarded  are provisional on Examination Board decisions which take place at the end of the Academic Year.

Coursework Questions

Question 1

Steam turbine driven synchronous generators are still commonly used in power generation, despite the decommissioning of coal fired power stations, for example from geothermal, nuclear and waste incineration sources. Describe in 1000 words with the aid of illustrations the operation of a large steam turbine system. Refer to the essential components, thermodynamic processes, efficiency and environmental issues.

[20 marks]

Question 2

The network in Fig.1 represents an existing primary substation with two parallel transformers and a new connection to a solar farm with an open circuit breaker. The existing 11 kV switchgear is rated to a fault level of 250 MVA. Assume all impedances are reactive (X»R) for simplicity and use a base value of 10 MVA.

a. Determine:

i. the fault level on the 11 kV busbars in the existing system, [5 marks]

ii. the new fault level when the circuit breaker is closed. [5 marks]

iii.the placement and value of a reactor to reduce the new fault level to within the switchgear rating explaining your reasoning, and [5 marks]

iv. the current each transformer provides in the event of a fault on the 11 kV busbars with the reactor inserted and the solar farm online. [5 marks]

b. Given that T3 is a star-delta step-up transformer, draw the circuit and determine the line and phase voltages and currents associated with both sides of the transformer under full-load conditions.  [5 marks]
