The ability of power system state estimator to detect and identify noise in the measurement data ... more The ability of power system state estimator to detect and identify noise in the measurement data enables it to provide a dependable data base for power system operation and control. If one or more of the telemetered measurements are contaminated with gross errors (bad data), the estimated system state and the corresponding data base will be biased. Bad data may occur as a single bad measurement or multiple bad measurements; therefore, the main objective of the power system state estimation is to minimize the bias in the data base [2].

The real-time data are processed by state estimator, a computer program which calculates voltage magnitudes and relative phase angles of the system buses. While the state estimator gives result similar to those available from conventional power-flow program, the input data and calculation procedure are quite different. Bus injections along with line flow measurements form the measurement vector in the state estimator in order to evaluate the final states of the power system. Test results without and with measurement noises have been presented. Estimator is also capable of identifying the bad data present in the measurement vector.
