Generator parameters, parameter estimation, saturation effect, synchronous generator
Most of previous work on online estimation of generator parameters does not consider the non-linear dynamic saturation effect in a disturbance process. In this paper, a new estimator is presented to incorporate the saturation effect in a disturbance process. The estimator focuses on recognizing the field winding and d-axis damper winding parameters of both salient-pole and round-rotor generators. The simulation results on three test cases demonstrated that not only the non-linear dynamic saturation effect in a disturbance process can be accurately captured in the parameter estimation but also the proposed estimator has a good capacity of handling measurement noises.
