Abstract
Abstract
In order to measure the electric energy and monitor the power quality in substations with accuracy, higher precisions are required for the gateway meters. Due to the wide dynamic range of the current and the nonlinearity of the compensation models, the calibration becomes complicated to guaranteeing the accuracy over the full range. For the purpose of decreasing the complexity of calibration, a piecewise and nonlinear compensation model is presented in this paper. With this model, all the values needed could be calibrated within two calibration points and the accuracy could achieve the requirements of precision over the full range. Results shows the efficiency of this method.
