Power Systems - ICA

Description
In this exercise you will work through a number of exercises within the study of a power system. This will utilise laboratory data which is provided for you. You are expected to perform calculations and simulation in MATLAB to compare with the laboratory data and complete the tasks as appropriate.

This ICA will assess the following Learning Outcomes as documented in the module specification and handbook:

Learning Outcome 1: Demonstrate a comprehensive and detailed knowledge of key aspects of high voltage generation and control in electrical power systems.

Learning Outcome 2: Critically analyse and evaluate power system problems with respect to generation, economic dispatch, frequency/voltage control and stability.

Learning Outcome 3: Identify and define complex electrical power systems problems and apply appropriate knowledge and tools to their solution.

Learning Outcome 4: Operate ethically in situations of varying complexity and predictability requiring the analysis of the power system components and system-wide issues.

Learning Outcome 5: Select and apply appropriate numerical methods to power systems problems.

Learning Outcome 6: Select and apply appropriate software to aid analysis of electrical power systems

Your ICA report will be a formal document and should record all your workings and include appropriate artwork (including screen shots, computer-based simulation models etc). Artwork must be presentable, consistent in style and format, and include numbered captions with brief descriptive text.

The ICA report must not exceed 20 single A4 sides. The report is to include a title page that includes the following: student name, student personal identifier, module code and date of submission. Appendices do not count towards the 20 pages and can be included as appropriate.

Introduction

Throughout the UK and across the global network there are significant kilometres of High Voltage transmission and distribution media. Most commonly are steel/aluminium catenary systems arranged as overhead lines and polyethylene/copper underground cables. Notwithstanding the external loading applied to these systems, they have inherent characteristics which can appear to metering equipment as if these systems themselves are acting as a load

a) Laboratory Based Activity
The objective of this section is to investigate the nature of inductive and capacitive loading when connected in Star and Delta, and how this affects power quality. Laboratory data is provided in Section 1f and should be used for the basis for all tasks in this section.

Data set 1a - Star Connected Load
Within a laboratory environment, resistive and inductive components have been connected in series to form a balanced Star configuration. A Power Quality Meter has been included to allow for measurements to be taken. Section 1f, table 1a shows actual values.

Each resistor has a nominal value of 300Ω. The inductor is initially set to 1.2H.
A value of 200V Phase to Neutral is applied to the circuit.
Appropriate measurements have been recorded for, Voltage, Current, Apparent Power, Real Power, Reactive Power and Power Factor.
The experiment has been repeated for values of inductance of 1.6H, 2.0H, 2.4H, 2.8H and 3.2H.

Data set 1b - Star Connected Load with Power Factor Correction

Within a laboratory environment, resistive and inductive components have been connected in series to form a balanced Star configuration and a capacitor bank connected in parallel. A Power Quality Meter has been included to allow for measurements to be taken. Section 1f, table 1b.
Each resistor has a nominal value of 300Ω. The inductor is set to 1.2H and the capacitor is initially set to 2uF.
A value of 200V Phase to Neutral is applied to the circuit.
Appropriate measurements have been recorded for, Voltage, Current, Apparent Power, Real Power, Reactive Power and Power Factor.
The experiment has been repeated for values of capacitance of 4uF and 8uF.

Data set 1c - Delta Connected Load
Within a laboratory environment, resistive and inductive components have been connected in series to form a balanced Delta configuration. A Power Quality Meter has been included to allow for measurements to be taken. Section 1f, table 1c shows actual values.
Each resistor has a nominal value of 300Ω. The inductor is initially set to 1.2H.
A value of 346V Phase to Phase is applied to the circuit.
Appropriate measurements have been recorded for, Voltage, Current, Apparent Power, Real Power, Reactive Power and Power Factor.
The experiment has been repeated for values of inductance of 1.6H, 2.0H, 2.4H, 2.8H and 3.2H.

Data set 1d - Delta Connected Load with Power Factor Correction
Within a laboratory environment, resistive and inductive components have been connected in series to form a balanced Delta configuration and a capacitor bank connected in parallel. A Power Quality Meter has been included to allow for measurements to be taken. Section 1f, table 1d.
Each resistor has a nominal value of 300Ω. The inductor is set to 1.2H and the capacitor is initially set to 2uF.
A value of 346V Phase to Phase is applied to the circuit.
The experiment has been repeated for values of capacitance of 4uF and 8uF.

Task - Analysis

Using appropriate software packages and manual calculations (excel is fine), confirm or otherwise the results recorded in Tables 1a to 1d. It is important that the comparison of these results is analysed within the final report.
Some points to start you off.
Can you identify any relationships, and can these be shown graphically?
What is the capacitor doing?
Have you commented on examples of reactive power that show ‘import and export'?
If the load was increased how might this effect the voltage?
What factors are significant when considering power flow?
Are there other significant factors that can be compared to theoretical study?
