Without a clear gras p of the fundamentals\, complexity cannot be mastered. Modern harmonic-ana lysis programs such as EasyPower\, ETAP\, DIgSILENT PowerFactory\, and sim ilar tools can solve complex power systems quickly\, but the engineer stil l needs to understand what the software is calculating\, which assumptions matter\, and whether the results make physical sense.\nThis presentation develops harmonic analysis from those fundamentals. Beginning with nonline ar waveforms and Fourier analysis\, it shows how a power system can be rep resented and solved as a separate electrical network at each harmonic freq uency. Using a practical medium voltage industrial system\, attendees are taken through the modeling of source impedance\, transformers\, capacitor banks\, motors\, plant loads\, and harmonic current injections\, followed by the calculation and interpretation of harmonic voltage and current dist ortion.\nParticular emphasis is placed on system resonance\, how capacitor banks interact with frequency-dependent system impedance\, why resonant f requencies move with operating conditions\, and how relatively small harmo nic currents can produce severe voltage distortion and current magnificati on.\nThe presentation then moves from analysis to mitigation\, comparing t he application and performance of notch-tuned\, detuned\, high-pass\, C-hi gh-pass\, and H-type harmonic filters. Practical examples illustrate tunin g\, damping\, filter interaction\, interharmonics\, resistor losses\, reso nance control\, and economic tradeoffs in filter selection.\nThe objective is not simply to teach engineers how to perform a harmonic study\, but to give them the foundation needed to understand\, challenge\, verify\, and confidently apply the results produced by advanced harmonic-analysis softw are. There will be three different sessions for this work.\n\nCo-sponsored by: IEEE Canadian Atlantic PES/IAS Chapter\n\nSpeaker(s): Paul Steciuk\, \n\nBldg: Sexton B BUILDING B229\, 1345 Norma Eddy Ln\, Halifax\, NS B3J 0 H6\, Halifax\, Nova Scotia\, Canada\, NS B3J 0H6\, Virtual: https://events .vtools.ieee.org/m/579180 LOCATION:Bldg: Sexton B BUILDING B229\, 1345 Norma Eddy Ln\, Halifax\, NS B 3J 0H6\, Halifax\, Nova Scotia\, Canada\, NS B3J 0H6\, Virtual: https://ev ents.vtools.ieee.org/m/579180 ORGANIZER:hamed.aly@dal.ca SEQUENCE:59 SUMMARY:Understanding Harmonic Analysis Part 1 URL;VALUE=URI:https://events.vtools.ieee.org/m/579180 X-ALT-DESC:Description: <br /><p style="text-align: justify\;">True underst anding starts with the basics.
