ABB Relion® 615 series Protection and control relays

ABB Relion® 615 series Protection and control relays

DESCRIPTION

The 615 protection and control series of relays is a member of ABB’s  Relion® product family. The 615 series relays are characterized by their  compactness and withdrawable plug-in unit design.

Ready-made adaptations to  application-specific requirements

The 615 series relays are available in ready-made  standard configurations for fast and easy setup.  All standard configurations can be tailored to  meet application-specific requirements using  the IEC 61850-compliant Protection and Control  IED Manager PCM600.

Human-machine interface

The 615 series relays are equipped with a large  graphical display which can show customizable  single-line diagrams (SLD) with position  indication for the circuit breaker, disconnectors  and the earthing switch. Also measured values  provided by the chosen standard configuration  can be displayed. The SLDs are customized  using PCM600 and can have multiple pages for  easy access to selected information. The SLDs  can be accessed not only locally but also via  the web browser-based HMI that has now  been enriched with a number of usability  enhancing features.

Standardized communication and redundancy

The 615 series relays fully support the IEC 61850  standard for communication and interoperability  of substation automation devices, including  fast GOOSE messaging and IEC 61850-9-2 LE,  and can now also benefit from the extended  interoperability provided by Edition 2.  The relays further support both the parallel  redundancy protocol (PRP) and the highavailability seamless redundancy (HSR) protocol,  together with the DNP3, IEC 60870-5-103 and  Modbus® protocols. With the protocol adapter  SPA-ZC 302, Profibus DVP1 can also be used.  The relays are able to use two communication  protocols simultaneously.

For redundant Ethernet communication,  the 615 series relays offer either two optical  or two galvanic Ethernet network interfaces.  A third port with a galvanic Ethernet network  interface provides connectivity of any other  Ethernet device to an IEC 61850 station bus  inside a switchgear bay. RED615 differs in that it  offers only two optical network interfaces. The  redundant Ethernet solution can be built on the  Ethernet-based IEC 61850, Modbus® and DNP3  protocols.

Main customer benefits

• Compact and versatile solution for utility and  industrial power distribution systems with  integration of protection, control, monitoring  and supervision in one relay

• IEEE 1588 V2 for high-accuracy time  synchronization and maximum benefit of  substation-level Ethernet communication 

• Large graphical display for showing  customizable SLDs, accessible either locally  or through a web browser-based HMI 

• Extensive life cycle services

Application

REF615 has been designed to be the main  overcurrent and earth-fault protection for  overhead lines and cable feeders, in either  isolated neutral, resistance-earthed,  compensated or effectively-earthed distribution  networks, depending on the standard  configuration.

REF615 is available in twelve standard  configurations. In addition to standard  configuration N, also L now provides maximum  functionality to allow fully flexible tailoring.  The major difference is that L includes support  for three combi-sensor inputs for phase currents  (Rogowski coil) and voltages (voltage divider),  whereas N supports conventional current and  voltage instrument transformers.  

The extensive earth-fault protection portfolio  has been expanded to include a unique  multifrequency admittance-based protection  for higher sensitivity and selectivity, in response  to the requirements of today’s growing cable  networks. The new earth-fault protection is  intended for all types of earth faults – continuous,  transient and intermittent – and combines both  reliability and sensitivity in one function.

Product highlights

• Extensive range of protection and control  functionality, either with sensors or  conventional instrument transformers  

• Extensive earth-fault protection portfolio with  unique multifrequency admittance-based  protection for higher sensitivity and selectivity 

• Advanced and fast fault location of short  circuits and earth faults
