Modeling of multi-phase synchronous machines in various coordinate systems

In industry, the solution to many problems is directly related to the development and research of synchronous machines (SM), which operate on a rectifying (asymmetric) load. This raises questions related to the selection of rational forms of representation of models and recommendations for their practical application for the study of various modes of operation of SM. Analysis of transients in the SM can be performed using mathematical models obtained in various coordinate systems. The paper presents a modeling method in reduced phase coordinates (FC), which allows one to obtain results that satisfy the calculation accuracy in FC in terms of accuracy of calculations, but with significantly lower computational costs.
