Nonlinear Modeling of Synchronous Generators Using Wavelet Transform- Experimental Results

Application of discrete wavelet transform for identification of a synchronous generator is investigated in this paper. Discrete wavelet transform guarantees global minimization and the accuracy of the identified model can be increased to the desired level by the multiresolution analysis (MRA) of the transform. The proposed method has been tested on a micro-machine synchronous generator. In this study, the field voltage is considered as the input and the active output power and the terminal voltage are considered as the outputs of the synchronous generator. Experimental results show good accuracy of the identified model following changes in the operating conditions.
