Delivering accurate and timely data to all

A new Supercalibrator approach has been introduced, which provides a practical approach for correcting the errors arising from instrumentation channels, system imbalances and asymmetries. The SuperCalibrator takes advantage of the huge data available at the substation level and readily accessible through a substation automation scheme. It performs a model-based filtering of the data and replaces all raw data with filtered data, providing accurate quantities for all voltages and currents in the substations. The SuperCalibrator is facilitated by the substation automation technology that makes all substation data readily accessible at a common point. It contributes towards the promise of substation automation to reliably provide accurate data to all clients. The SuperCalibrator approach has the capability of identifying symmetrical as well as asymmetrical events that generate alarms and associates the alarms to events with high confidence level.
