This paper describes an algorithm for detecting power system faults and estimating the pre- and post-fault steady state values of the voltages and currents. The proposed algorithm is based on the Kalman filter and hypothesis testing. It is shown that a power system fault is ideally suited for single sample hypothesis testing. Test results are included.
