PARTIALLY NON-SELECTIVE PROTECTION SYSTEM OF CATENARY
Abstract
A partially non-selective system of protections is proposed, which provides, as well as non-selective system of protections, fault clearing at any point of the zone between substations without specified time, but with a small amount of non-selective disconnections of switches of traction substations. An algorithm for the identification of areas of nonselective disconnections is given. The reliability of the system and possibility of its use as a model are justified.
