Abstract of doctoral thesis AGGELOS MOSCHOUDIS

The subject of the dissertation is the optimized design of a salient pole synchronous gener-ator suitable for small hydroelectric power plants. In this context as a point of reference, the data concerning the basic generator’s specifications which have been determined in the prelim-inary study of the small hydroelectric project are used. Initially, the preliminary design gener-ator’s parameters are specified while the design is implemented and confirmed with the Finite Element Method, as it has already been implemented in a previous post-graduate diploma thesis of the Phd candidate. The items that can be investigated are listed below:The subject of the dissertation is the optimized design of a salient pole synchronous gener-ator suitable for small hydroelectric power plants.

Initially, the preliminary design gener-ator’s parameters are specified while the design is implemented and confirmed with the Finite Element Method, as it has already been implemented in a previous post-graduate diploma thesis of the Phd candidate. The items that can be investigated are listed below: The extension of the optimization investigation by the method of sensitivity analysis with additional parameters. Harmonics and total harmonic distortion coefficient investigation of generator’s output voltage as a function of the load variation. Thermal stress and mechanical stress criteria. Development of an appropriate cost function in order to be determined the generator’s construction and operating costs. Applicability investigation of different optimization methods in synchronous generators design such as genetic algorithms and multicriteria optimization methods (through the creation of solutions map from which the best of them will be selected using an appro-priate algorithm). Other types of synchronous generators investigation such as: permanent magnet synchro-nous generators (PMSG), double layer fractional pitch stator windings, multiphase stator windings and skew stator slots.
