In this study, the characteristic analysis of a permanent magnet synchronous generator was performed using the analytical method, and the validity of the analytical method was compared with that of the finite element method (FEM). For the initial design, the rotor size was selected using the torque per rotor volume method, and the stator size was selected according to the saturation of the stator iron core. In addition, fast Fourier transform analysis was performed to determine the appropriate magnet thickness point, and it was confirmed that the open circuit and armature reaction magnetic flux densities were consistent with the FEM analysis results. Based on the analytical method, the generator circuit constants (phase resistance, back EMF, and inductance) were derived to construct an equivalent circuit. By applying the equivalent circuit method to the derived circuit constants, the accuracy of the equivalent circuit method was confirmed by comparing the FEM and experimental results.

The load characteristic analysis of permanent magnet synchronous generator is presented. An internal impedance mathematic model of the generator was built with phasor analysis method for analyzing the relationship between exterior voltage characteristic or voltage regulation rate, active power and armature reactance. The research results demonstrated that the internal impedance of generator has both current and power factor angle negative feedback characteristic, which makes the voltage regulation rate be improved to a certain extent and the improved effect lying on both the direct-axis armature reactance under condition of an inductive load and the quadrature-axis armature reactance under resistive load. Additionally, an optimal range of the armature reactance being of less voltage regulation rate was determined according to numerical calculation and analysis. An experimental result based on the experimental measurement and data analysis of exterior voltage characteristic corresponds to the theoretical calculation demonstrated the correctness of the research model based upon the armature reaction analysis. Those can provide the theoretically guidance to the electromagnetic design of permanent magnet generator.

Power Generation Performance

This paper presents a nonlinear magnetic equivalent circuit method and an electromagnetic characteristic analysis and verification of a wound rotor synchronous generator (WRSG). The reluctance generated by the stator, rotor, and air gap is subdivided to form a reluctance construction. A nonlinear magnetic equivalent circuit (MEC) for the WRSG is constructed and solved by an iteration method. Moreover, to calculate the inductance of the generator, the reluctance circuit of the d−qaxis is constructed, and the inductance of the generator is obtained using the initial relative permeability of the material. Using the electromagnetic parameters obtained via the MEC method, the power generation characteristics of the generator are predicted. The results of this MEC method are also verified by comparing them with the finite element analysis (FEA) results and experimental results.
