Please download the following fixed admittamce Matrix simulated converters  and run them on your Computer. Compare the simulation Speed, accuracy and fexiblity of These fixed admittamce Matrix-Models with your own simulator.

The Control System of the model “WIND_DFIG_OFFSHORE_10S” contains very large number of Simulink-blocks. This will cause slow Simulation. You have to convert the Block s”Reg10″ to S-Function blocks using the Simulink-Coder Toolbox (rtw). You get at least 6 times faster Simulation.

Some of the features of the fixed admittamce Matrix simulated Converters can be sumarized as follows:

– All the developed SimuPec-blocks use piecewise linear devices for IGBTs  and Diode (NOT AVERAGING MODELS). However the contibution in the admittance Matrix is fixed admittance Gs=1/ohm ;
– All the developed SimuPec-blocks use only Simulink C-S-Functions;
– All the developed SimuPec-blocks behaves exactly like builtin Simulink blocks, they have their own parameters, they can be copied and pasted;
