Dear Simone<br>In 1 month I will start my postgrade in Brazil and I am going to use SCILAB for modeling power system. <br>As a result, I will make the "SCICOS-PST". <br>Meanwhile, I almost finished a model of a SVPWM, SPWM.Park, Clarke transform and THD.<br>
The video conference finished today. But I can organize another one in february, where you can participate, even as an expositor. The main problem is that if you speak spanish. <br> Regards<br>Raymundo<br><br><div><span class="gmail_quote">2008/1/30, Simone Mannori <<a href="mailto:Simone.Mannori@inria.fr">Simone.Mannori@inria.fr</a>>:</span><blockquote class="gmail_quote" style="margin-top: 0; margin-right: 0; margin-bottom: 0; margin-left: 0; margin-left: 0.80ex; border-left-color: #cccccc; border-left-width: 1px; border-left-style: solid; padding-left: 1ex">
Dear Raymundo,<br><br>There is a recurring problem using Scilab/Scicos for engineering<br>applications: the identification of systems parameters.<br><br>One of the difficulties of the models used in SimPower is the<br>mathematical/physical modeling used in the block. The Italian electrical<br>
engineers (and the industries that make motors and generators) use<br>slightly different model from the Simulink one.<br><br>Unfortunately there is not 1:1 correspondence between them. Usually, we<br>prefer build the model from scratch using elementary blocks.<br>
<br>If you are interested to develop a power system toolbox for Scicos you<br>are very welcome :) Scicos-PST ?<br><br>We are working in close contact with Microchip for Scicos-FLEX.<br>Microchip have several product lines for power system applications and<br>
they have expressed their interest to extend FLEX to motor control.<br><br>Another interesting point is the modeling of the power section (MOSFET<br>or IGBT bridge) using Modelica. This kind of simulation could be<br>extremely useful because you can study the behavior of the power section<br>
under stress (e.g. when you have a short circuits between phases or very<br>long connection cables).<br><br>I suppose that you are aware of the interaction between the control<br>strategy and the EMC issues. In Europe the EMC is a pass/fail strict<br>
law.<br><br>If you are interested in this field - as I am - we can start a<br>productive collaboration.<br><br>Thanks again for using Scilab/Scicos :)<br><br>Simone Mannori - Scilab/Scicos Embedded Applications Eng.<br><br>
P.S. May I join - of just see - your video conference ?<br><br><br><br>On Tue, 2008-01-29 at 16:34 -0500, Cordero R. wrote:<br>> Dear Simone,<br>><br>> Firstly, I want to apologize for my error. I want to answer a email<br>
