Abstract :
The estimation of a synchronous machine´s electrical parameters using an extended Kalman filter (EKF) is proposed. The estimation method is evaluated using digital computer simulations, as well as practical measurements on a microalternator. The captured data are used, together with an initial set of machine parameters, as an input to the EKF to estimate an improved set of parameters. The results indicate that the parameter estimation method is valid under certain conditions, but that with high-order models it is computationally intensive, and that certain parameter estimates are noise-sensitive.<>
