Abstract

The present specification provides a method and device for determining a disturbance condition in a power transmission line. The method may include obtaining a plurality of sample values corresponding to an electrical parameter measured in each phase. The method may further include determining a plurality of magnitudes of the electrical parameter corresponding to each phase based on the corresponding plurality of sample values and determining a plurality of difference values for each phase based on the corresponding plurality of magnitudes. The method may include processing the plurality of difference values using a machine learning technique to determine the disturbance condition. The disturbance condition may be one of a load change condition, a power swing condition, or an electrical fault condition. The method may also include performing at least one of a protection function or a control function based on the disturbance condition.
