Abstract :
The authors present the implementation of a power-system state estimator on a personal computer. The method uses a weighted-least-squares (WLS) algorithm to estimate the system unknowns. The program was developed in two parts. Part one uses only the real and reactive line flows as measurements. Part two adds the measurement of bus voltage magnitudes, bus real and reactive injected power, and line-current magnitudes. The convergence rates of these two methods are compared.<>
