摘要
Disclosed herein is a method of compensating for the distorted secondary/ current of a current transformer. The method includes steps (a), (b) and (c). At step (a), the saturated section of the current transformer is detected. At step (b), fault current generated during a fault in a power system is represented using an AutoRegressive (AR) model, with the fault current being assumed to be a combination of a Direct Current (DC) offset component, a fundamental wave component and harmonic components. At step (c), coefficients of the AR model are estimated and the secondary current during saturation of the current transformer is compensated, based on the secondary current data sampled in the unsaturated section.
