Quality evaluation and automatic calibration method forpower grid on-line simulation data

Aiming at the problems of more sources, difficult integration, poor quality and unable toreflect the practical power grid status in the power grid on- line simulation data model, considering themodel matching, on- line data parameters, the interior characteristic of on- line data, puts forward aquality evaluation and automatic calibration method to apply to power grid on-line simulation data. The ;application result shows that the method can make quality evaluation and automatic calibration onpower grid on-line simulation data from multi angle and multidimension, so as to promote drasticallythe precision of power grid on-line safety and steady verification.
