A new Kalman filtering-based technique is presented for estimating power system frequency deviation and its average rate of change during emergency operating conditions that may require load shedding. This method obtains the optimal estimate of the power system frequency deviation from noisy voltage samples and the best estimate of the mean system frequency deviation and its rate of change while accounting for low frequency synchronizing oscillations which occur during large disturbances. The proposed technique is a two stage algorithm which uses an adaptive extended Kalman filter in series with an adaptive linear Kalman filter.
