Grid Solutions Multilin F35 Cost-effective Protection & Control for Single/Multiple Distribution Feeders The MultilinTM F35 feeder protection system provides feeder protection, control, monitoring and metering in an integrated, economical, and compact package. As part of the Universal Relay (UR) Family, the F35 provides cost-effective solutions and features high-performance protection, expandable I/O options, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The F35 can be configured to protect up to six feeders or protect up to five feeders when bus voltage measurement is required. It also provides fast and deterministic execution of programmable logic, which is necessary for substation automation applications. Graphical programming tools (Viewpoint Engineer), supported by a library of logic components, make the F35 simple to use and configure. Protection & Control • Instantaneous and time phase, neutral, negative sequence and ground overcurrent protection • Neutral & auxiliary overvoltage, phase & auxiliary undervoltage, under frequency • Wattmetric ground fault detection, breaker control, and breaker failure • Four-shot autorecloser for up to 6 breakers and broken conductor elements • Protection and control functionality in one box, reducing the number of devices • Flexible and cost-effective protection and control for multiple distribution feeders backed by many years of field experience • High density inputs/outputs to support the control of many switchyard assets – all from one powerful device • Advanced, high speed communications provide increased system stability at a reduced cost using control schemes • Integrated large, full color display, for real-time visualization and control of the protected bay • Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications • 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 • 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 GOOSE messages going beyond the substation, which enables wide area protection and control applications • Increased network availability via failover time reduced to zero through IEC® 62439-3 “PRP” support • Supports latest edition of waveform capture (COMTRADE 2013) simplifying fault records management Applications • Primary protection and control for multiple distribution feeders • Distribution load shedding schemes based on voltage and frequency elements • Busblocking/interlocking schemes • Throw over schemes (bus transfer scheme applications) • Backup protection for transmission lines, feeders and transformers • Distributed Generation (DG) interconnect protection, including active and passive anti-islanding 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 Cyber Security • CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP, AAA, Radius, RBAC, Syslog) Monitoring & Metering • Advanced recording capabilities with highcapacity event recorder, configurable and extended waveform capture and data logger • Metering: current, voltage, power, energy, frequency, and harmonics • Phasor and c

F35 Feeder Protection System PRP or HSR standard redundancy, plus Star, Ring and Point-to-point network support. For time synchronization purposes, this Process bus module can become an IEEE 1588 slave clock (61850-9-3 profile) or a 1588 Grand Master clock which removes the need of external time sources connected to the process bus network. Customers who may not be using GE MU devices, could use MU from other vendors. Interoperability with MU from other vendors is expected when they comply to the mentioned standards. IEC 61850-9-2 HardFiber Process Bus The IEC 61850 Process Bus module is...
