| Abstract |
This paper presents a rotor shape design using genetic algorithm to reduce the total harmonic distortion(THD) of a conventional 10kVA winding synchronous generator. The applied system uses a phase and line-to-line power together from the diesel engine generator. For the improved total power quality, the THDs of phase and line-to-line voltage have to be reduced together. According to the winding pitch, THD of phase and line-to-line voltage are analyzed to select the initial winding model of a conventional synchronous generator. Based on the initial stator winding model of a conventional synchronous generator, the rotor shape is re-designed using genetic algorithm to improve the output power quality and efficiency. Four important parameters of generator rotor shape are optimized by genetic algorithm. The fitness function is determined by the THD and core loss of generator.
In the FEA(Finite Element Analysis) and the practical experiments of designed 10kVA generator, the THD of phase and line-to-line voltage are much decreased with similar operating efficiency in the designed rotor and the conventional stator structure. |
