:) Dear Forum Users,

I am pasting my forum site link where you can download a fully functional spice
software for your power harmonics analysis. The software is free no
limitation and you can use it to predict behavior of a network on
the presence of harmonics (through current injection method). You
can also use the software to predict series or parallel resonance,
conduct spectrum analysis, simulate effect of a passive filter tuned
to a particular frequency and others. I have been using the software
to conduct test cases of my own and so far I find it very useful.
Once you have familiarized yourself on its functions, you can expand
its usage to other application such as transient switching, model
the effect of a reactor, for example to mitigate impulses, and
others.

I have created this forum to serve as a venue where we can interact
and share information and messages on power system and power quality
issues. Topics which I hope to be discussed in this forum includes:

1) Power system modeling and prediction
-load flow analysis
-short circuit analysis
-motor starting analysis
-Others

2) Power quality modeling and prediction
-power system harmonics
-lightning surges
-transient switching
-noise
-Others

3) Power quality detection and monitoring
- Power disturbance ( impulse, noise, overvoltage, undervoltage,
swell, sag) using disturbance monitors such as BMI,
Dranetz,Fluke,
etc.
-Ground resistance and resistivity testing using Vibroground,
AEMC, and others.
-Power harmonics monitoring using BMI, Dranetz, Fluke, and others.

4) Power Quality Problem Correction
Sizing, Selection, Installation, and Maintenance of
-Surge protectors
-Reactors
-Passive and Active filters
-Transformers
-Lightning Protection
-Other technologies aim to improve power quality problems


5) Standards dealing with Power Quality Issues
-IEEE 1100 Powering and Grounding of Sensistive electronics
equipments
-SEMI F47
-CBEMA/ITIC Curve
-IEEE 519
- Others

6) Power Electronics
-AC Drives
-DC Drives
-Modeling Techniques to predict their behavior in the network
- Others


Thank you and enjoy this very powerful software. :)
