Alstom / GE Multilin N60 Network Stability and measurement

GE Multilin N60 relay network stability and synchrophasor measurement system is a flexible device intended for the development of load shedding, remedial action, special protection schemes and wide area monitoring and control. Like no one device before, the N60 shares real-time operational data to remote N60s so the system can generate intelligent decisions to maintain power system operation.

GE Multilin N60 relay Key Benefits

• Scalable synchrophasor measurements with up to 6 PMUs per IED reducing synchrophasor cost by up to 80%
• 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
• Exceeds the latest IEEE C37.118 standard for PMU measurement devices with a TVE of less than 1%, Protection and Metering class synchrophasors and multi-cast IEC 61850-90-5 support
• Uninterrupted synchrophasor measurements during fault and disturbances providing highly reliable capture of data for critical control functions and postmortem analysis
• Three independent fiber or copper Ethernet ports for simultaneous/dedicated network connections with advanced 1 microsecond time synchronization via LAN with IEEE 1588 support
• Simplified system integration with direct connection to JungleMUX SONET, TN1U SDH and TN1Ue SDH networks
• CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC CIP, AAA, Radius, RBAC, Syslog)
• Supports latest edition of waveform capture (COMTRADE 2013) simplifying fault records management
• 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

Applications
• Decrease blackouts by identifying network instabilities and taking fast preventative action
• Increase utilization of existing investments by identifying power transfer capability on existing lines
• Compliments existing protection and control by sharing power and utilization information with existing systems to enhance system security
• Facilitate contingency planning through continuous synchrophasor data collection and postmortem analysis
• Provides enhanced state estimation for SCADA to optimize system wide load shedding and remedial action schemes
• Mitigate system critical conditions such as power system dampening and loss of synchronism through the use of enhanced automated control to reduce outages
