Description

GE / Alstom D60 Line Distance Protection System

GE MiCOM D60 Relay is suitable for protecting transmission lines and cables including lines equipped with series compensation. GE MiCOM D60 Relay supports dual-breaker applications and can be applied in single-pole or three-pole tripping applications. The D60 is applicable to different teleprotection schemes and includes inter-relay protection communications via direct fiber as well as different interfaces. The D60 also provides synchrophasor measurement over Ethernet per IEEE C37.118.

GE MiCOM D60 Relay Key Benefits

• Five zone quad or mho, phase and ground distance protection
• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
• Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
• Reliable and secure protection on series-compensated lines
• Superior phase selection algorithm
• Supports multiple standard pilot schemes
• Flexible programmable logic for building customized schemes
• Simplified teleprotection interfaces with direct I/O communications
• Robust network security enabling Critical Infrastructure Protection
• Phasor Measurement Unit (synchrophasor) according to IEEE® C37.118 (2011) and IEC® 61850-90-5 support
• Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
• An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors

GE MiCOM D60 Relay Applications
• Overhead lines including series-compensated lines and underground cables
• Single and dual-breaker circuits requiring single pole/three-pole autoreclosing
