On line synchronous generator parameters estimation based on applying small disturbance on excitation system using ANN

This paper presents a technique for on-line estimation of synchronous generator parameters, using an excitation disturbance. To illustrate and verify the proposed algorithm, some excitation disturbance tests are conducted on an actual hydro generator. Machine response to the applied disturbance is processed by proposed technique using artificial neural network method, (ANN). The estimated parameter values are compared with manufacture´s data.
