Understanding Power Quality & HarmonicsPower quality, especially harmonics, can be a significant and difficult issue in utility distribution systems. Due to their complex nature, harmonic related problems are difficult to analyze and troubleshoot. Advanced knowledge on network frequency responses is often needed.
This one-day tutorial is designed to help utility engineers bridge the knowledge gap in the subject of power system harmonics. Different from industry presentations, this tutorial adopts a university teaching style to cover fundamental concepts of the subject. Practical industry cases will be used to demonstrate how the application of the harmonic theories can help mitigate real life industry problems.
