Overview and Example Test Results of Modern Pilot Schemes for Coordination of Line Distance Protection Relays
Main Article Content
Abstract
The paper presents a short review of pilot schemes which are available in modern line distance protection relays, and example results of common pilot scheme tests with the testing methods description. Some differences in implementations of selected pilot schemes have been shown for comparison reasons. Distance protection coordination functions have been tested for GE Multilin UR series devices. Every type of available pilot scheme has been checked in synthetic tests and during the real coordination between D60 and D90Plus devices. For the POTT scheme, coordination between two L90 protections has been carried out by a sort of available different data communication link types, for comparison reasons too.
