short circuit calculation
(OP)
Hi guys,
I need a powerfull short circuit, load flow and voltage drop calculation program. I will calculate a generation+consumer systems and will make relay co-ordination. There are araound 600 relays (different types-oc/ef). Could you advise me which one i must sellect and what kind of details i must be awere of?
Thanks in advance.

I'm sure there are many more that can be found by searching the web. Also if you just need it for occasional studies, you might find it more economical to let a consulting engineer do them for you.

I have also found that it pays to check the database thoroughly to see if it contains the relay/breaker types you will most frequently use - it can be very cumbersome to add user-defined relays to some software. For example, in Canada we have a large base of Federal Pioneer breakers and relays. These are invariably missing from US-based software packages.
That said, I haven't found any software that I am a huge fan of. Our office uses Aspen OneLiner and some CYME modules. We have a corporate license for ETAP Powerstation, but we don't have it installed at our local office yet. For what it's worth, ETAP PowerStation claims a large following among consulting companies in its literature.
You can also check out SKF, Dapper, EasyPower, etc. I think all these companies will give you a free demo CD, and you can download free demos from many websites, for example CYME.

I suggest EDSA software.
Visit www.edsa.com, you can find all the information regarding this powerful and very comprehensive power analysis software. This is very user friendly; backed by Autodesk's Actrix 2000 for it's drawing engine which uses plugs and sockets technology and with a very extensive library also. It has an expert system that will help you select the most appropriate curves for your protection although you can select your own choice. You can request for the the brochures or demo cd's also or try their on-line demo.
