Signal Reconstruction Based on Newton's Forward Divided Difference for SCADA of Wide-Area Intelligent Energy System

Accurate calculation of power quantities is important to the control and management of energy system. To reduce the design cost and computational burden in the terminal power meters, an efficient data acquisition technique based on waveform reconstruction is proposed to transfer correct power signal for calculation of power quantities. In the structure of wide-area intelligent energy system, the effectiveness and performance of the proposed technique can be verified.
