Modeling approach of a generator with non-linear load in embedded electrical network

This paper deals with a modeling approach of an embarked electrical network. This network is composed of a synchronous generator feeding linear and non linear load. In order to simplify the identification of inaccessible part of the generator, a specific modeling approach of the machine is established. Thus, the rotor is modeled by generalized transfer functions. Its order is chosen to have the desired accuracy and short computation time. Transfer function parameters can be easily identified by SSFR (StandStill Frequency Response) identification method. The generated model takes into account the strong interaction between all network components and variable topology of the non linear load. Some time domain simulation results are given in the end of the paper and illustrate the efficiency of this modeling approach.
