Investigation of effect of stator resistance on accuracy of generator parameters identification with SSFR method
In stand still frequency response, extrapolation in low frequency will be used to calculate Ld0 (initial value of d-axes inductance), Lq0 (initial value of q-axes inductance) and Ra (stator resistance).Because of dependency of generator parameters to this parameters, accuracy of these parameters for exact identification is so important. In this paper effect of stator resistance on generator parameters identification has investigated by sensitivity analysis and then this effect has shown on practical SSFR data of Shahid Rajaei powerplant which are used for parameters identification by pattern search method.
