EE 1004 POWER QUALITY 3 0 0 100
AIM
To study the various issues affecting Power Quality, their production, monitoring and suppression.
OBJECTIVES
i. To study the production of voltages sags, overvoltages and harmonics and methods
of control.
ii. To study various methods of power quality monitoring.
1. INTRODUCTION TO POWER QUALITY 3
Terms and definitions: Overloading, under voltage, sustained interruption; sags and swells; waveform distortion, Total Harmonic Distortion (THD),
Computer Business Equipment Manufacturers Associations (CBEMA) curve.
2. VOLTAGE SAGS AND INTERRUPTIONS 7
Sources of sags and interruptions, estimating voltage sag performance, motor starting sags, estimating the sag severity, mitigation of voltage sags, active series compensators, static transfer switches and fast transfer switches.
3. OVERVOLTAGES 10
Sources of over voltages: Capacitor switching, lightning, ferro resonance; mitigation of voltage swells: Surge arresters, low pass filters, power conditioners – Lightning protection, shielding, line arresters, protection of transformers and cables, computer analysis tools for transients, PSCAD and EMTP.
4. HARMONICS 12
Harmonic distortion: Voltage and current distortion, harmonic indices, harmonic sources from commercial and industrial loads, locating harmonic sources; power system response characteristics, resonance, harmonic distortion evaluation, devices for controlling harmonic distortion, passive filters, active filters, IEEE and IEC standards.
5. POWER QUALITY MONITORING 13
Monitoring considerations: Power line disturbance analyzer, per quality measurement equipment, harmonic / spectrum analyzer, flicker meters, disturbance analyzer, applications of expert system for power quality monitoring.
