GE Multilin UR & URPlus Family

GE Multilin UR & URPlus Family

Proven, State-of-the-Art Protection & Control Systems

From the power plant to the power consumer, the MultilinTM UR & URPlus family of advanced protection  and control relays provides one integrated platform that delivers leading edge protection, control,  monitoring & metering solutions for critical power system applications. Featuring proven protection  algorithms, expandable I/O, integrated monitoring & high accuracy metering capabilities with the  latest in communications technologies, the Multilin UR & URPlus family of devices provides the situational  awareness needed for a reliable, secure and efficient modern grid.

Key Benefits

• Modular construction: common hardware, reduced stock of pare parts, plug & play modules for  maintenance cost savings and simplification (Multilin UR) 

• Proven flexibility and customization capabilities make the Multilin UR/URPlus devices suitable to retrofit  almost any kind of legacy P&C scheme 

• Large HMI and annunciator panels provide local monitoring & control capabilities, and backup the  substation HMI 

• Phase measurement Unit (synchrophasors) according to IEEE® C37.118 (2011) and IEC® 61850-90-5  directly streamed from your protective device 

• Embedded IEEE 1588 Time Synchronization Protocol support eliminates dedicated IRIG-B wiring  requirements for P&C devices (Multilin UR) 

• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and  comprehensive process bus support (IEC 61850-9-2LE or IEC 61869 or IEC 61850-9-2 Hardfiber)  ensures interoperability, device managing optimization and reduced cost of ownership 

• Routable GOOSE (R-GOOSE) enables customer to send GOOSE messages beyond the substation, which  enables WAPC and more cost effective communication architectures for wide area applications 

• Increased network availability via failover time reduced to zero through IEC® 62439-3 “PRP” support 

• Supports IEEE C37.111-1999/2013, IEC 60255-24 Ed 2.0 COMTRADE standard

Applications

• Protection, control, monitoring and supervision of power assets across generation, transmission,  distribution, substation and industrial systems 

• Utility substation and industrial plant automation 

• Digital fault recording and Sequence of Event (SOE) recording 

• Predictive maintenance through data analysis and trending 

• Synchrophasors based monitoring and control system with specialized PMU devices that support  multiple feeders providing P&M class synchrophasors of voltage, current, and sequence components 

• Complex protection & control and wide area monitoring solutions with complete diagnostic and  automation capabilities (Multilin URPlus)

Protection and Control

• Fast, segregated line current differential &  distance protection functionality in one device 

• Phase distance (5 zones) with independent  settings for compensation 

• Single-pole tripping, breaker-and-a-half with  independent current source support 

• Comprehensive generator protection with  100% stator and field ground fault detection 

• Protection and control functionality in one  box, reducing the number of devices 

• Integrated large, full color display, for real-time  visualization and control of the protected bay

Advanced Communications

• 3 independent Ethernet ports for simultaneous  & dedicated network connections with  IEEE 1588 support 

• IEC 61850-9-2LE/IEC 61869 networked or  IEC61850-9-2 Hardfiber process bus support
