Parallel calculation methods use in electrotechnical complexes

This article explains how to use parallel methods of calculation in electrotechnical complexes. The article provides a classification of the existing mathematical models and carries out their preliminary assessment. Here is a simple mathematical model based on the FRRM electrical equivalent circuit which is also necessary for the calculation formula. The mathematical model obtained by the energy method is based on co-energy. Methods were analyzed and were subject to evaluation according to the following criteria: ease of the main drive sizes selection, the first estimate for the optimal ratio of the geometric parameters of the electrical machine, the complexity of the calculation.
