ETAP Power Quality - Fundamentals of Harmonics

etap.com - Power Quality - Fundamentals of Harmonics
This webinar presents the fundamentals of harmonics, harmonic distortion and its sources, and related issues such as premature equipment failure or unplanned downtime.
The presentation will demonstrate how to identify, analyze, and minimize or eliminate harmonics problems using the ETAP software.
The following topics are covered:
- Modeling of harmonic sources
- Identify parallel resonance condition and its resonance frequency
- Total harmonic voltage and current distortion evaluation
- Harmonic violation alerts
- Harmonic filter performance evaluation

I am using etap V12.6 and i could not find the part to add harmonics to inverter or wind turbine. How can this be done in this version

[@scylam1]

Thanks for the great video. May I ask if AHF can be added into the system to perform result simulation? And capacitor banks with / without inductors to simulate possible resonance scenario?

Thanks for the tutorial but I have a question about the report. I want to see current harmonics at the point of common coupling but the report shows only the voltage harmonics of the buses. So how can I see the individual current harmonics in the report?

[@FebriantLeocesio]

Pelin Fidan I have the same problem now. did you find the solution already?

[@JuanPerez-zx6cq]

@@FebriantLeocesio just put a very low impedance between your circuit and the grid, then on the harmonic load flow select to plot the harmonic currents in that impedance.

How can you add line reactor to the model. I used the current limiting reactor, but I don't think that's the right one. I need to add a 3% line reactor on a 460V 100 hp motor with a 6 pulse VFD.

Hi, Can ETAP used to simulate Transient Stability because of Arc Furnace and its impact of negative sequence which is presenting to Generator?

[@andrewcooper2479]

It concerns me that when you add a harmonic source and enter the magnitudes of each harmonic order you make no mention under what conditions (e.g. short circuit power / impedance of the mains supply) that those magnitudes should be entered. The magnitudes of the harmonic currents of a 6 pulse VSD for example will be very different depending on the impedance of the mains supply that the VSD is connected to. If the ETAP software does not define under what conditions the magnitudes of the harmonic currents should be entered, how can it accurately calculate the resulting THDi and THDv at the PCC? If the ETAP software does not know the conditions under which the magnitudes of the harmonic currents were entered how does it calculate the change in these magnitudes based on the characteristics (e.g. short circuit power / impedance) of the circuit being modelled in the software?

@@ETAPsoftware Wow it took 2 years for a reply and even then I did get an answer but instead just instructed to contact ETAP technical support. Why can’t you get technical support to answer my question here for everyone interested in your software to see?

Why do triplen harmonics does not shows up in the simulation?

[@justinp.s9941]

did u had known to display triplen harmonics?

[@lyamineboukari2505]

Only 5th, 7th, 11th and 13th harmonic orders are generated from the harmonic source used (the inverter).

I really liked the video, I already subscribed.
It helped me a lot.
Could you help me with a video on how to design a non-linear load?
Please.

Shouldn't it be 0.48 kV instead of 480 kV at 33:09 ?

[@ETAPsoftware]

Thank you for your interest in ETAP Software and thank you for your feedback. Yes, you are correct. The Max kV should be 0.48. This will not have an impact on the final HA study results. This values is only used for equipment evaluation purposes. Thanks for pointing this out.

[@grapegh0stx]

Good day, I am trying to figure out why significant VTHD drop when it passes through the transformer? from 7.29% to 1.27% VTHD
as far as i know, only triplen harmonics gets stuck on delta side of the transformer and 5,7,11,13th etc should still be reflected in the primary side? thank you.
