“…There are programs that allow to perform calculation of volumetric models of magnetic systems, such as ELCUT and the like, but their high cost and complexity in the development limit their use. The solution is to develop methods for calculating magnetic systems by the finite difference method [1][2][3][4][5][6].…”

The article presents a method for calculating the magnetic systems of volume models by the finite difference method, taking into account the separation of dissimilar media for an axially symmetric system. A special feature of the presented calculation method is the automation of determining the boundaries of the media of volumetric models by taking into account the magnetic resistance of adjacent nodes relative to the calculated node. The results of the program for calculating the magnetic field pattern are presented on the example of a threedimensional model of a synchronous generator with a two-core magnetic system used as part of a wind generator. Three-dimensional graphical dependences of the change in the magnetic induction value inside the stator winding coil of a synchronous generator are constructed for a rotor with an external magnetic core, for a rotor with an internal magnetic core, and for a rotor with two magnetic cores simultaneously. The calculation of the magnetic system is presented in article, the method of the example synchronous generator with dual magnetic system, determining the maximum value of magnetic induction, penetrating the winding of the synchronous generator in the direction of the r axis. Based on the picture of the three-dimensional distribution of the magnetic induction vector and the constructed three-dimensional graphs of the changes of the values of the magnetic induction vector along the r axis for an external magnetic core, the magnetic core and the double-core magnetic system is determined by the efficiency of the use of the dual magnetic system, where the magnetic induction inside the stator winding increases in average 2 times, which entails an increase in the power of the synchronous generator 4 times.

The article presents a method for calculating the magnetic system using the finite difference method for the axisymmetric system. The finite difference method for constructing a model of the generator's magnetic field allows integrating differential equations into partial derivatives by reducing the equations in finite differences. A special feature of the presented calculation method is the automation of determining the boundaries of the media interface, by taking into account the magnetic resistance of adjacent nodes relative to the calculated node. The main characteristic of a magnetic field is magnetic induction, which is a vector quantity. Magnetic induction is calculated based on the distribution pattern of the magnetic potential. Based on the Poisson and Laplace equations presented in the article, a computer program was developed for automating the calculation of the magnetic induction vector. The results of the program for calculating the magnetic field pattern on the example of a synchronous generator with a two-circuit magnetic system used as a part of a wind generator are presented. Graphical dependences of the change in the value of magnetic induction inside the stator coil of a synchronous generator are constructed for a rotor with an external magnetic circuit, for a rotor with an internal magnetic circuit, and for a rotor with two magnetic circuits simultaneously. In the calculation of the magnetic system, as presented in article, by the method of the example synchronous generator with dual magnetic system, the maximum value of magnetic induction, penetrating the winding of the synchronous generator along the axis r, when the internal circuit is 0.21 T, using the external loop, the value of the magnetic induction vector is 0.283 T. When using a two-circuit system, the value of the magnetic induction vector is 0.483 T.
