Discussed on: 07 February 2025
Due Date: 16 May 2025, 18:00
Submission Format: Electronic Only (including zip file for any additional data you wish to submit) on Blackboard (I will create a submission link closer to the due date).
This assignment comprises 50% of the assessment for ELEC3213/ELEC6222. You should note that you may need to acquire new knowledge (in addition to the material presented in the lectures) to complete the work successfully; many of the lectures include recommendations for further reading. As a guide, you could expect to spend around 40 hours on the completion of this assignment, not inclusive of additional reading recommended in the lectures.
Objectives:
The objectives of this assignment are as follows:
1. To determine an appropriate network design for a given scenario, informed by industrial and regulatory requirements.
2. To complete the sizing of components so that the network is able to operate within limits, including under outage cases.
3. To design a protection scheme, which ensures that faults within the network can be dealt with while keeping customer interruptions to a sensible minimum.
4. To evaluate your own design, and identify lessons learned which you could apply to future similar work.
Report Requirements:
You should submit a report that meets the following requirements:
• Addresses all of the Outputs listed in the technical description which follows
• Is no longer than 12 pages, inclusive of the reference list. The minimum font size is 11 (Calibri), with standard margins (2.54cm).
• Where diagrams are included, they are properly referenced in the main text and are clearly readable at 100% (printed) size.
• Contains a short appendix listing any additional electronic files, drawings or other resources which you have submitted electronically (all supporting files should be submitted as a .zip file as per the instructions on the blackboard for this assignment).
• The report is an individual assessment; you should clearly acknowledge all sources of help. You are welcome to discuss your ideas with others in the cohort, but you must ensure that the work submitted is your own.
Software Selection:
There are a number of software choices available to allow you to conduct load flow and fault analysis, including one (PowerWorld) which is freely available to install on your personal computers. However, if you have experience using another tool, you can choose that instead (please discuss with the module leader first).
Part 1 – Network Design
The first part of your assignment involves the review of network design options. The conceptual overview of the system that you are considering is shown in Figure 1. You should note that this diagram is not intended to represent the full electrical layout, but instead gives options for the connectivity that would be available. Circuit breakers are not shown and should be inserted as appropriate. You do not need to use all lines; you should seek to provide evidence for the routes chosen.
Figure 1 Overview Diagram of Network
Important Points to Consider:
1) What is the required level of redundancy for this type of network?
2) How will the network perform under outage cases? How might this influence the selection of the layout?
3) Where do you need to locate switching points in order to facilitate the isolation of specific components (this links to point number 1 above).
4) The indicative diagram represents a whole bus substation with one node; this does not mean that you are restricted to using a single bus system. Also note that for power world, you don t need to represent each bus in a detailed manner, and just a single-bus representation is sufficient for each bus. But in your report, you are expected to describe the type/configuration of each bus.
5) The more circuits you add, the higher the redundancy, but the more complex the protection becomes.
6) You should consult the spreadsheet ELEC3213_ELEC6222_Student_details.xlsx, hosted on blackboard, to verify the line lengths applicable for your specific case. This document will also detail the system loadings that you are designing to (note that these differ between students).
Outputs:
• A short discussion of the possible design options, which describes clearly the advantages and disadvantages of the options available to you.
• A clear statement of your recommended design, including a system diagram. This should show all buses, transformers, switching points, feeder circuits, loads. You do not need to consider the details of anything below B5, B7, B9, B11.
• You should provide clear reasons for your choices.
Part 2 – Component Sizing
Having determined the appropriate layout for the network, you should select appropriate size of lines and transformers to meet your requirements. Consideration should be given to power flows under normal conditions, and also the worst-case contingency scenarios that you expect the network to endure.
To assist you with selecting appropriate components, documents containing suitable asset data are provided on the course resources page; note that you would have also covered many of the calculation methods needed to calculate parameters yourself. You should also consult the spreadsheet ELEC3213_ELEC6222_Student_details.xlsx, hosted on the course resources page, to verify the line lengths applicable for your specific case.
Outputs:
• Discussion of approach taken to determine the size of the components.
• Powerflow results to show that your network meets requirements under both normal and contingency scenarios.
Part 3 – Protection Scheme
Upon completion of Part 1 and Part 2, you should now have a design for your network which has been checked using your power flow model. The next step in the design is to determine an appropriate protection scheme. In doing this, you should consider the following factors:
1) How will your protection system be influenced by the redundancy requirements of your network?
2) How many switching operations will you need to undertake to clear a fault?
3) What are the appropriate protective devices to use in the different parts of the network?
4) Which devices should be coordinated together?
5) Will the coordination be affected by an outage on the system?
6) How will you ensure that system components can be safely disconnected and isolated for maintenance?
Outputs:
• A clear protection strategy for your network, describing the behaviour you would expect to see for certain types of faults.
• The type of protective device used at each location should be identified. You do not have to identify specific manufacturers, or commercially available devices, but you should indicate the required ratings.
• Three specific examples of how the protection will respond to a fault.
Part 4 – Evaluation & Lessons Learned
As you progress through this coursework, you will find that you learn from the experience of trying to achieve certain objectives; perhaps you will decide to take one option, but then subsequently discover that another choice was better. In the final part of the coursework, you are asked to evaluate your design.
Outputs:
• Discussion of challenges faced in developing the design, and lessons learned as a result.
• Evaluation of the design that you have produced, including recommendations for further work that could be done to improve on it if additional information was available to you.
