【Abstract】 In accordance with the nature of the complexity of multiple noise sources of exciter sets in power plants, a reasonable physical model for the exciter noise radiation multi-input/mono-output system is set up by the partial coherence technique. The analysis and identification of the noises of the exciters are carried out. The results of analysis are satisfactory and provide a basis for controlling noises of the exciter sets in power plants.更多还原
