Abstract: | This paper presents a novel ultra-high-speed directional protection scheme developed using mathematical morphology (MM). The MM technique proposed is used to extract transient features from fault-generated voltage and current wave signals propagating along transmission lines during a post-fault period. Fault direction is determined by two composite relaying signals which are composed of the extracted transient features. A variety of fault scenarios has been simulated to evaluate the validity of the proposed scheme. |
