Abstract

The present work consists in the determination of the parameters of a salient pole synchronous generator by means of the finite element method and the magnetic flux density in the air gap, these parameters have the objective of symbolizing the characteristics of the behavior of said synchronous generator in state stationary and dynamic. Through the implementation of an approximately real design of the three-phase salient-pole synchronous generator in steady state, 2D electromagnetic simulations were carried out in the FEM simulation software. The inductance parameters of the synchronous generator in the direct reference (Ld) and quadrature (Lq) axes were determined, with the specific materials that will be constituted in the ferromagnetic core of the salient pole synchronous generator. Electromagnetic simulations were shown, under the criterion of the geometric symmetry of the salient pole synchronous generator, adding boundary conditions to greatly reduce the number of complex iterations that the FEM simulation software must produce. With the electromagnetic simulations carried out, the maximum flux density in the iron gap was obtained to obtain the inductance in the direct (Ld) and quadrature (Lq) axis. The numerical values obtained from the inductance in the reference axes show that the finite element method is appropriate for obtaining the electrical characteristics of a salient pole synchronous machine, since said machine is not exposed to physical stress, safeguarding its structure and performance
