electrical design simulation program

electrical design simulation program

electrical design simulation program

(OP)
I am interested on getting an electrical design simulation program. Been looking around, someones are to expensive and others fall short on feautures. My question is which is thre best under $1000. Thanks in advance.

RE: electrical design simulation program

I'm only a third year student in an electricial and electronic degree course, however the main programs we use are MatLab by MathSoft, good for modelling etc and SimuLink for control. Mathematica is in fact a great Maths package, better than MatLab in my opinion but probably more expensive

RE: electrical design simulation program

There is a free power systems simulation package called PSCAD/EMTDC available FREE at www.hvdc.ca. It is an evaluation version with a 15 electrical node limit.

It is a time domain based simulator, which uses a Fortran engine to solve electrical differential equations - much faster than Matlab and Simulink.

It contains a full controls library and a Matlab interface.

RE: electrical design simulation program

If you don't mind the follow up call from a salesman, then Deta in the UK have a fantastic program that they will despatch on cd to you as an evaluation. There is no time limit and it really works !! don't have their url to hand but it probably was .com or .co.uk

I also understand there is soon to be a web based java version of electronics workbench ( i use the standard one myself) i don't know if it is by them or someone that is using their format.

good luck and every success

regards

Andy

RE: electrical design simulation program

PSCAD/EMTDC appears to be suitable for applications that do not require more accurate generator and motor modeling with their associated phenomena including power flow, short circuit currents, voltage drops, etc.

RE: electrical design simulation program

In response to comment by jbartos on Dec. 22:

Actually, the PSCAD/EMTDC simulation of the transient response of electric machines is quite accurate. The syncronous machine model contains a 'Multi-Mass' algorithm to accurately simulate rotor torsional effects and sub-syncronous resonance.

In my experience using the program, I have never had a problem with lack of accuracy.

Response to the previous posting:
1. The software is very suitable and accurate for modeling transient phenomena, which was not denied anywhere, and it is included in Reference 1 "Foreword."  This is in agreement with the above postings. What is at a question are symmentrical component models suitable for the steady state load flow, short circuit and voltage drop analysis, especially a suitability to align them with any particular industry standards. There are no references cited to any industry standards in Reference 1, except perhaps over the Help System in EMTDC User's Guide.
2. Reference 2 "Table of Contents" does not really list Generators and Motors; however, it does list Transformers, Transmission Lines and Surge Arresters. It seems to be referring to academic papers and few industry standards, which is excellent for its purpose pertaining to transient models, however, less convenient for practical applications and equipment meeting industry standards. There is an enormous amount of practical and theoretical knowhow needed for proper correlations. For example, where to fit "Closing and Latching Capability" under Circuit Breakers in Reference 2 Section 7-10.
3. The generator positive, negative and zero sequence parameters and their relationships to subtransient, transient and synchronous reactances seems to be omitted from References 1 and 2.
4. The software and its results cannot easily be compared to industry widely used software, e.g. DAPPER, ETAP, etc.
5. Etc.

RE: electrical design simulation program

Why do not you try the Electric Transient Program known as ETAP.  I think it is well known program and I have been using it for quite time without any problem.

RE: electrical design simulation program

ETAP is not exactly under 1000US$. In fact, the ETAP E1 certified for the nuclear power plant electrical system analysis may cost as much as 160,000US$.

RE: electrical design simulation program

I agree ETAP is expensive but I find it good.  This is general information that may benefit others.  He may have the money in the future.

RE: electrical design simulation program

Is EMTDC anything like EMTP Sounds like a DC version. I don't know if EMTP will suit electron's needs, but the ATP version can be had for considerably less than $1000 (free) if you meet the licensing requirements (promise not to sell it and never did). This is no limited trial version. Try http://www.ee.mtu.edu/atp/ for more information.

RE: electrical design simulation program

Response to Steve A (Visitor):

Actually, EMTDC and EMTP were born of the same concept introduced by Hermann W. Dommel in a paper called "Digital Computer Solution of Electromagnetic Transients in Single and Multiphase Networks", released in (I believe) 1969.

Although similar, EMTP and EMTDC have been developed separately since.

In the 1970's, EMTP was found to be inadequate for simulating Power Electronic circuits, so a new Fortran based simulation engine was developed in Manitoba, Canada to address these needs: EMTDC. EMTDC is capable of solving not only DC transtient solutions but AC as well.

Over the years, EMTDC has been developed commercially into a unique program, containing sophisticated algorithms to enhance efficiency and speed of simulation.

When used with it's GUI (PSCAD), I have found it to be quite a powerful software package for simulating any type of electrical (and mechanical) system.

A free evaluation version can be downloaded from www.hvdc.ca

Thank you all for the support. The information has been very helpful.
