Assessment Criteria: Practical Project Validation Page 1
Overview
This assessment is an individual task and it covers the following learning outcomes:
― ULO1 - Demonstrate specialised knowledge and technical competence in finding
engineering solutions to a range of scenarios.
― ULO3 - Communicate project details through the use of oral and written
communication to a professional audience.
Assessment Criteria:
In your final report, you must address the following points
Summary of the results from project design and component validations: 8 Marks
In this part, you need to discuss the results that you have obtained from your project design and
practical project validation. Also you need to provide clear explanation indicating the reasons
whether for matching or not matching these results.
Three-Phase Representation of the Whole Project and Relevant Calculations: 6
Marks
In this part, you need to draw the three-phase equivalent circuit of the whole project and you
need to calculate the line current and voltage at different stages as you have done during the
practical project validation
Single-Phase and Per Unit Representation of the Whole Project along with Relevant
Calculations: 6 Marks
In this part, you need to draw the single-phase circuit and finally convert the parameters into
per unit by considering suitable base values of volt-ampere and voltage.
Power/Load Flow Study: 0 Mark
This part is optional and its upto you whether you will include this or not.SEE210: Power Engineering Design

Guidelines:
First Part
The first part is mainly related to your two previous assessment and this will allow to further
justify your understanding on the concepts related to power engineering design.
Second and Third Parts
The following steps will help you to complete these two parts:
Step 1: Start with the generation system. Consider a three-phase generator/power supply with
the voltage as indicated your project outline. Draw an equivalent circuit in three-phase.
Step 2: Get a three-phase (Y-Y) transformer. Also draw the three-phase equivalent circuit of
the transformer. Now combine this equivalent circuit with the three-phase generator/power
supply in Step 1. The primary of this transformer will be connected to the generator/power
supply.
Step 3: Connect one-side of a three-phase transmission line to the secondary of the transformer
in Step 2. Draw the three-phase equivalent circuit from the generator/power supply to the
transmission line (i.e., generator/power supply+Y-Y transformer+transmission line).
Step 4: Get another three-phase (Y-Y) transformer. The primary of this transformer will be
connected to the transmission line in Step 3. Draw the three-phase equivalent circuit from the
generator/power supply to this transformer (i.e., generator/power supply+Y-Y
transformer+transmission line+ Y-Y transformer).
Step 5: Connect one-side of a three-phase transmission/distribution line to the secondary of
the transformer in Step 4. Draw the three-phase equivalent circuit from the generator/power
supply to the distribution line (i.e., generator/power supply+Y-Y transformer+transmission
line+Y-Y transformer+distribution line).
Step 6: Draw the equivalent circuit diagram of the load based on the information provided in
the project outline. Connect this load with the distribution line in Step 5. Draw the three-phase
equivalent circuit from the generator/power supply to the load (i.e., generator/power supply+YY transformer+transmission line+Y-Y transformer+distribution line+load).
Now you will have the full circuit diagram of a three-phase power system which will answer
the first part of the project question.
Step 7: Draw the single-phase equivalent circuit from the generator/power supply to the load
as obtained in Step 6 (i.e., generator/power supply+ transformer+transmission line+
transformer+distribution line+load).SEE210: Power Engineering Design

Now you will have the full circuit diagram of a single-phase power system which will answer
the second part of the project question.
Step 8: Draw the single-line diagram from the generator/power supply to the load as obtained
in Step 7 (i.e., generator/power supply+ step-up transformer+transmission line+ step-down
transformer+distribution line+load).
Step 9: Use relevant theories from Week 9 to draw the circuit in per unit quantity.
Step 10: Use relevant circuit theories to calculate the values of current and power losses in
different sections of the network in per unit as well as the actual values.
