Dear Sir/Mdm, I have done the power system report but plagiarism is quite high and i am not sure whether the Q1, Q2 and Q3 i have done correctly. Please assist to fine tune my english in Q1 and check Q2 and Q3 answers are correct.

304SE Power Systems

Course Work 2021

Individual Report

There are three questions in this assignment. Answer to all the questions must be contained in a single report, in the same order as the questions, with appropriate heading. The cover page of the report should include the following: The University, the course, students name, Student number and date of submission.

The report should include Table of contents.

Question 1

You are required  to prepare a report on Electrical Power System of a specific country. Select one country. The country that you select must start with first letter of your first name (For example if your first name is Marie then you choose a country name which starts with letter M ( for example Malaysia)). 

The following are the general guidelines for preparing report.

Word Count overall 1500 words ± 10 %.

You are encouraged to obtain and review information from websites of Electricity Authorities, IEEE, IET, International Energy Agency and/or similar Associations for preparing report.  Please include list of references in Appendix (not included in word count)

You must cite references for data, graphs, charts, figures, illustrations, and diagrams in your report.

You are encouraged to use following Section Headings in preparing your report for this question.

Question 2

Figure 2 shows the circuit of a simple power system. The ratings of the generators, transformers and the motors are as shown in the figure. The reactance of lines 1 and 2 are 40 W and 50 W respectively. Assume that system is unloaded, and the generators are generating their rated voltage. Select the generator G₁ ratings as base values.

Choose the fault location for your calculations based on the last digit of your student number as indicated in the following table:

                                                                       Figure 2

For a symmetrical three phase fault on the bus selected by you:

(i)         Draw the reactance diagram for the fault with all the reactances marked in       per unit.

(ii)        Determine the Thevenin’s equivalent circuit which can be used to calculate         the fault current.

(iii)       Calculate the fault current in ampere and fault power in MVA.

(iv)       Calculate the fault current contribution from the generator connected to the    bus on which you have selected for fault calculation.

Question 3

A four-bus power system is shown in Figure 3. Bus-1 is a slack bus. Bus -4 is a PV buss, and the other two buses are PQ buses. The initial voltages of the slack and PV buses are as shown in the figure. The data for the buses are given in the table-1 below. The values of the real and reactive power shown in the table are on a base of 100 MVA.

The line impedances in per unit and real and reactive power in per unit are on a common base. Assume the initial value of the angle at the PV bus to be zero (0) and the voltages at buses 2 and 3 to be 1.0?0°

.

Table-1                                                                                   Base MVA=100

Choose the line impedances for your calculations based on the last digit of your student number as indicated in the following table:

Figure-3

(a)        Create the circuit, in “PowerWorld” software. Assume a base power of 100 MVA. All the field values sch as voltage and phase angle at every bus and real and reactive power at both end of every line must be included in the circuit. The created circuit diagram (before simulation) must be included in your report.

(b)        Simulate the circuit using Gauss-Seidel iterative method for a single iteration. Record the values of the voltage magnitudes in pu and phase angle in degrees at      buses 2,3 and 4. The simulated diagram with all the field values clearly shown must be included in your report.

(c)        Calculate the bus admittance matrix for the circuit using the impedance values    given in the table. Printout the bus impedance matrix generated by the PowerWorld program and compare it with the bus impedance matrix calculated by you.

(d)        Calculate the voltage in pu and the phase angle in degrees at the buss 2 and 3   after the first iteration using Gauss-Seidel method and compare it with the         results             recorded in part (b).
