До визначення параметрів моделей трансформаторів
2017
In the article the method of calculation of transformer models parameters from its passport data is offered. An obligatory transition is offered from the traditional series curcuit of magnetization to parallel one. It allows to find exact parameters for the models of transformers in SimPowerSystem and also parameters of the equivalent transformer inductance coils which are magneticaly bounded. The offered method is realized in MathCAD program and allows quickly find necessary parameters. Test of method on SPS-model showed high exactness, providing divergence of electric values in a fifth meaning number.
