Design and Analysis of a Synchronous Generator Using Finite Element Method Based ANSYS-Maxwell

Abstract

The most basic electrical machine that converts mechanical energy into electrical energy is synchronous machines. Synchronous machines can be operated at high speeds and low speeds for different power plants. In terms of system planning, it is important to examine the operating characteristics of the machine at idle and variable load conditions in these cycles. It is very important that generators, which are the basic components of turbines in power plants, have high efficiency when they are designed. While synchronous generators are being designed, many parameters that are compatible with each other must be arranged in an appropriate way. The efficiency of generators can vary greatly by changing very important parameters in the design. In this study, the analysis, design and analysis of the characteristic parameters of a synchronous generator are carried out with the ANSYS-Maxwell-Rmxprt integrated design and simulation program based on Finite Element Method (FEM). In this paper, parameters such as efficiency, induced voltage, phase currents and voltages and output torque of a three-phase synchronous machine were obtained depending on the electrical angle change.
