Subject description
Introduction to power quality, basic terms and definitions, overview of power quality standards. Transient phenomena, long term voltage deviations, short term voltage deviations, voltage unbalance. Waveform distortions; dc components, harmonics, interharmonics. Voltage fluctuations – flicker. Voltage sags and interruptions. Supply interruption indices.
Measurements of power quality parameters, permanent monitoring systems. Modelling of parts of power networks and loads for power quality analysis; system impedance characteristics. Methods of sharing responsibility for power quality distortion between network and customer side. Spreading disturbances across the network.
Measures for power quality improvement.
Objectives
The student will acquire the knowledge of basic power quality terms and supply voltage characteristics and will also improve their knowledge of measurement performance, analysis of measurement results of power quality parameters, and possible measures to improve power quality.
