harmonics modeling

[polychronis]

Dear collegues,
i am trying to develop a simulation for harmonics in power distribution system within an industrial plant (case study, not specific).
the incoming network, the transformers, cables, motors, non linear loads etc must be simulated as preferably passive parts (inductors, resistors, capacitors).
Any proposal for the models?
Any good book, paper, etc?


Best regards,
chronis

Hello,

The model and degree of detaill will mainly depend on your need. I mean, if you are interested in seeing what happens with the loads then you need a detailled model of them, otherwise, you may represent some equivalent.

In order to simplify, loads may be represented with current sources for each harmonic frequency present.

Good references, there are many:

a) Arrillaga, Power System Harmonics
b) IEEE Tutorial Course about Hamonic Modelling
c) There are some other papers from IEEE eated to the analysis and application of the results, but they use will depend on your specific interest.

Can you tell us more about this:

IEEE Tutorial Course about Harmonic Modelling

I did a quick search on line but could not find anything.

Dear Louis,
Arillaga.... i have just ordered it!
papers: in industry application society from 1989-today, you will find only results, not methodology. I cannot understand why there are not many papers with specificaly rfering to the models they use for their studies. They only conclude to the fact that simulation results approaching reality.

IEEE 519/92 is also referinf in modeling in brief, but not much.

Eg: you can simulate roughly a motor at steady load/speed with an R-L but when doing harmonics analysis you do not include both R and L variation over frequencies.

You might try Dr Mack Grady’s PCFLO and PCFLOH [www.ece.utexas.edu/~grady/PCFLO.html] or HASIP [www.ece.utexas.edu/~grady/HASIP.html]

to be more specific:
when do we use the short circuit equivalent and when the steady state when we do models for harmonics analysis?

Hello,

Only to clarify one of my previous posts:

Tutorial on Harmonics Modeling and Simulation
IEEE Power Enginering Society Task force on Harmonics Modeling
Document 98TP125-0

This is a document prepared by IEEE and it is a "collage" of papers, they have modelling, test systems and so on.
Besides, it has lots of references to further search.

Best Regards
