Relion® 615 series

2 Feeder protection and control | REF615

Compact and versatile solution for utility and industrial power distribution systems

REF615 is a dedicated feeder IED perfectly aligned for the protection, control, measurement and supervision of utility and industrial power distribution systems including radial, looped and meshed networks, also involving possible distributed power generation. REF615 is a member of ABB’s Relion® protection and control product family and its 615 series. The 615 series IEDs are characterized by their compactness and withdrawable-unit design. Re-engineered from the ground up, the new 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices.

ApplicationREF615 provides feeder overcurrent and earth-fault protection for distribution networks, including substation busbar protection applying the reverse interlocking principle, or GOOSE messaging over a switched Ethernet station bus. REF615 fits both isolated neutral networks and networks with resistance or impedance earthed neutrals. Furthermore, making use of the IED’s advanced inter-station communication facilities, REF615 can also be applied for protection of ring-type and meshed distribution networks as well of radial networks. The protected networks may also involve multiple infeed and distributed power generation. As of now, the REF615 is available in nine predefined standard configurations to suit the most common feeder protection and control applications.

Protection and controlREF615 offers directional and non-directional overcurrent and earth-fault protection and thermal overload protection. Some standard configurations allow as an option admittance-based, harmonics-based or wattmetric-based earth-fault protection to be used in addition to directional earth-fault protection. The admittance-based earth-fault protection ensures a correct operation of the protection even though the connection status information of the Petersen coil would be missing. The admittance protection offers good immunity to varying fault resistance values, easy setting principles and improved sensitivity of the protection. Furthermore, REF615 features sensitive earth-fault protection, phase discontinuity protection, transient/intermittent earth-fault protection, phase overvoltage, undervoltage and residual overvoltage protection, positive phase-sequence undervoltage and negative-phase sequence overvoltage protection. Overfrequency, underfrequency and frequency gradient-based protection is offered in standard configurations H and J. The IED also incorporates optional auto-reclose functions for arc fault clearance on overhead line feeders.

Enhanced with optional hardware and software, the IED also features three light detection channels for arc fault protection of metal-enclosed, air-insulated switchgear. Fast tripping increases staff safety and security and limits material damage in an arc fault situation.

A standard configuration IED can be adjusted using the signal matrix functionality (SMT) or the graphical application configuration functionality (ACT) of the Protection and Control IED Manager PCM600. The ACT supports creation of multi-layer logic by combining function blocks along with timers and flip-flops. By combining protection and logic functions the IED can be modified to fit the requirements of the application.

REF615 integrates functionality for the control of a circuit-breaker via the front panel HMI or by means of remote controls. REF615 also features two control blocks which are intended for motor-operated control of disconnectors or circuit breaker trucks and for their position indications. Further, REF615 offers a control block which is intended for motor-operated control of one earthing switch control and it’s position indication. The number of controllable primary devices depends on the number of available inputs and outputs in the selected configuration.

Sensor supportThe standard configuration G includes one conventional residual current (I0) input and three sensor inputs for the connection of three combi-sensors with RJ-45 connectors. The sensor inputs allow current and voltage sensors to be used in compact medium voltage (MV) switchgear instead of conventional measuring transformers. Compact MV switchgear, such as ABB’s SafeRing and SafePlus, are designed for applications, like compact secondary substations, wind turbine power plants, small industry installations and large buildings. As an alternative to combi-sensors, separate current and voltage sensors with adapters can be used.

Standardized communicationREF615 features genuine support for the IEC 61850 standard for inter-device communication in substations. It also supports the DNP3 protocol, the IEC 60870-5-103 protocol, and the industry standard Modbus® protocol.

For a self-healing Ethernet solution the IED offers an optional fibre-optic communication module providing two optical and one galvanic Ethernet network interfaces. Alternatively, the IED features an optional galvanic communication module with two galvanic and one optical Ethernet network interfaces or three galvanic interfaces. The third Ethernet interface provides connectivity of any other Ethernet devices to an IEC 61850 station bus inside of a switchgear bay. The self-healing

Protection function overview of the J configuration of REF615.

Ethernet solution constitutes a cost efficient communication loop controlled by a managed switch. The managed switch controls the consistency of the loop, routes the data and corrects the flow of data in communication disturbance situations. The self-healing Ethernet ring can be built on the Ethernet based IEC 61850, Modbus® and DNP3 protocols.

The implementation of the IEC 61850 standard in REF615 covers both vertical and horizontal communication, including GOOSE messaging with binary and analog signals and parameter setting according to IEC 61850-8-1. For time-critical applications REF615 supports synchronization over Ethernet using SNTP or over a separate bus using IRIG-B.

Preventive condition monitoringFor continuous control of its operational availability REF615 features a comprehensive set of monitoring functions to

supervise the IED itself, the CB trip circuit and the circuit breaker. Depending on the chosen device configuration, the IED monitors the wear and tear of the circuit breaker, the spring charging time of the CB operating mechanism and the gas pressure of the breaker chambers. The IED also supervises the breaker travel time and the number of CB operations to provide basic information for scheduling CB maintenance.

Single line diagramThe 615 series IEDs with large graphical display offer customizable single line mimic diagrams (SLD) with position indication for the switching devices. The IED can also display measured values provided by the chosen standard configuration. The SLD is also available via the web-browser based HMI. The default SLD can be modified according to user needs using the graphical display editor of PCM600.
