The detailed syllabus for Power Quality B.Tech (R13) seventhsem is as follows<\/p>\n
OBJECTIVES:<\/strong><\/p>\n UNIT I : INTRODUCTION TO POWER QUALITY<\/strong> \u00a0 [9 hours] UNIT II : VOLTAGE SAGS AND INTERRUPTIONS<\/strong> \u00a0 \u00a0[9 hours] UNIT III : OVERVOLTAGES<\/strong> \u00a0 \u00a0[9 hours]\n
\nTerms and definitions: Overloading – under voltage – over voltage. Concepts of transients – short\u00a0duration variations such as interruption – long duration variation such as sustained interruption. Sags\u00a0and swells – voltage sag – voltage swell – voltage imbalance – voltage fluctuation – power frequency\u00a0variations. International standards of power quality. Computer Business Equipment Manufacturers\u00a0Associations (CBEMA) curve.<\/p>\n
\nSources of sags and interruptions – estimating voltage sag performance. Thevenin\u2019s equivalent source\u00a0– analysis and calculation of various faulted condition. Voltage sag due to induction motor starting.\u00a0Estimation of the sag severity – mitigation of voltage sags, active series compensators. Static transfer\u00a0switches and fast transfer switches.<\/p>\n
\nSources of over voltages – Capacitor switching \u2013 lightning – ferro resonance. Mitigation of voltage\u00a0swells – surge arresters – low pass filters – power conditioners. Lightning protection \u2013 shielding – line\u00a0arresters – protection of transformers and cables. An introduction to computer analysis tools for\u00a0transients, PSCAD and EMTP.<\/p>\n
