Abstract
In this paper, an analytical model aimed at reducing computational times for the analysis of classical synchronous generators is proposed and validated. While the proposed model's attractiveness comes from its simple and fast nature, however, it also features excellent levels of accuracy. This is achieved by the model's ability to consider aspects like saturation and space harmonics. Such features are usually investigated with computationally-heavy finite element analysis. The proposed method shows that an appropriate flux linkage map of all the machine windings as a function of currents and rotor position can be used to accurately consider these features at no cost of time or accuracy. Furthermore, the integration of the skewing effect within the model has also been proposed by incorporating it within the flux linkage map. The proposed method is investigated through the use of a 72.5kVA, wound field, salient pole synchronous generator. The results are compared with those of a finite element model and also against experimental measurements on a physical prototype. The advantages of the proposed procedure are discussed, where the model's suitability for carrying out lengthy and multiple simulations and its flexibility are highlighted.
