The course will present the following topics :
The objective of this course is to investigate the advanced aspects of power quality considering the context of new technologies, integration of renewables and smart power grids. After a quick review of some basic theory, the students will be encouraged to research trends and perform extensive computer simulations using Matlab/Simulink.
QEE Overview and Basic aspects of harmonics
• Fourier trigonometric series;
• Order, frequency and phase sequences;
• Harmonic distortion indices;
• Power factor and cos φ.
Harmonic generating sources -
• Single-phase sources (linear sources, switched sources);
• Three-phase converters;
• Arc furnaces;
• Saturable equipment;
• Static compensation system (SVC).
Static converters
• Operation;
• Types;
• Waveforms;
• Power factor and harmonics generation.
Consequences of harmonics -
• Increase in the “consumption” of reactive power;
• Heating;
• Overvoltage in capacitors;
• Abnormal torques in engines;
• Abnormal dielectric stresses;
• Serial / parallel resonance.
Harmonic filters -
• Damped passive filters;
• Passive tuned filters;
• Electromagnetic filters.
Conceptual aspects of unbalanced harmonics -
• Phase sequences;
• Examples of measurements.
New Research Areas: Superharmonics, etc.
Extensive Use of MatLab / Simulink Simulations
Discussions about the generated articles -
