Abstract

Power disturbances have always been an important issue in the power system protection. This paper presents a novel algorithm, improved hit-or-miss transform (IHMT), for the detection of power disturbances. IHMT is a morphological operator that uses a structuring element (SE) consisting of two sets. Besides, it employs basic morphological operators only, which ensures the algorithm to perform fast calculation. Applied to power systems, IHMT detects the location and duration of disturbances. A variety of power disturbances have been simulated to evaluate the validity of IHMT.
