EE6005 POWER QUALITY – SYLLABUS – R- 2013 

OBJECTIVES: 

 To introduce the power quality problem
 To educate on production of voltages sags, over voltages and harmonics and methods
of control.
 To study overvoltage problems
 To study the sources and effect of harmonics in power system
 To impart knowledge on various methods of power quality monitoring.

UNIT I INTRODUCTION TO POWER QUALITY

Terms and definitions: Overloading – under voltage – over voltage. Concepts of transients – short
duration variations such as interruption – long duration variation such as sustained interruption. Sags
and swells – voltage sag – voltage swell – voltage imbalance – voltage fluctuation – power frequency
variations. International standards of power quality. Computer Business Equipment Manufacturers
Associations (CBEMA) curve.

UNIT II VOLTAGE SAGS AND INTERRUPTIONS

Sources of sags and interruptions – estimating voltage sag performance. Thevenin’s equivalent source
– analysis and calculation of various faulted condition. Voltage sag due to induction motor starting.
Estimation of the sag severity – mitigation of voltage sags, active series compensators. Static transfer
switches and fast transfer switches.

UNIT III OVERVOLTAGES

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. An introduction to computer analysis tools for
transients, PSCAD and EMTP.

UNIT IV HARMONICS 

Harmonic sources from commercial and industrial loads, locating harmonic sources.Power system
response characteristics – Harmonics Vs transients. Effect of harmonics – harmonic distortion – voltage and current distortion – harmonic indices – inter harmonics – resonance. Harmonic distortion
evaluation – devices for controlling harmonic distortion – passive and active filters. IEEE and IEC
standards.

UNIT V POWER QUALITY MONITORING

Monitoring considerations – monitoring and diagnostic techniques for various power quality problems – modeling of power quality (harmonics and voltage sag) problems by mathematical simulation tools – power line disturbance analyzer – quality measurement equipment – harmonic / spectrum analyzer –
flicker meters – disturbance analyzer. Applications of expert systems for power quality monitoring.
