| DESCRIPTION | This study-unit describes the application of the study and analysis of power quality issues with respect to electrical engineering. The following topics are studied in this unit: - Power Quality Definitions - Power Factor Correction: Power Factor, Active and Reactive Power, Displacement and True Power Factor, Power Factor Improvement, Power Factor Correction Voltage Rise Due to Capacitance, Static VAR Compensators, Application of Synchronous Condensers - Harmonics and Basics of EMI: Harmonics produced by non-linear equipment and the European regulations will be covered. Harmonic Phase Rotation and Phase Angle Relationship, Causes of Voltage and Current Harmonics, Harmonic Signatures(Fluorescent Lighting , Adjustable Speed Drives, Personal Computer and Monitor, etc). Effect of Harmonics on Power System Devices (Transformers, AC Motors, Capacitor Banks, etc..), Electrical & Magnetic Fields, Electromagnetic Interference Terminology (Decibel (dB), Radiated Emission, Conducted Emission, Common Mode Rejection Ratio, Common Mode Noise , etc.) - Other power quality issues: Transients, Long and Short voltage variations, flicker, imbalance, distortion, frequency variations. - Measurement of Power Quality: Harmonic Analyzers, Transient-Disturbance Analyzers, Data Loggers and Chart Recorders, True RMS Meters, Power Quality Measurements Study-unit Aims: The aims of the study-unit are to present the electrical engineering student with knowledge in the areas of: Power Quality Measurement and Regulations, Power Factor Correction, Harmonics and Basics of EMI, and various other power quality occurrences such as :Transients, Long and Short voltage variations, flicker, imbalance, distortion, frequency variations. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - carry out power quality related measurements, - identify and quantify the measurements, - calculate the elements required for correction. 2. Skills: By the end of the study-unit the student will be able to: - use equipment related to power quality related measurements, - use software for identification and quantification of the measurements. Main Text/s and any supplementary readings: - Electrical Power Systems Quality, H. Wayne Beaty, Roger C. Dugan. - Power Quality in Electrical Systems, Alexander Kusko, Marc Thompson. - Harmonics and Power Systems, Francisco C. De La Rosa. |
