Recognizing of Traveling Wave Patterns on Digital Substations for Automatic Reclosing of High-Voltage Overhead-Cable Power Lines Transmissions

The development of Smart Grid, Digital Substation concepts, is characterized by the complication of protection and automation systems, which requires the development and implementation of new algorithms of work. In this article there considered a new approach to the organization of automatic reclosing of high-voltage overhead-cable power lines transmissions in metropolitan areas, based on the recognizing of traveling wave processes due to a fault. There described the correlation method of estimation of traveling wave processes, which makes it possible to estimate the faulted section. There performed the simulation of faults at different sections of the overhead-cable power line, and its traveling wave patterns were obtained. There described the prospects for the development of the method and the direction of further research.
