Relion 65 series Feeder protection and control REF65
Compact and versatile solution for utility and industrial power distribution systems REF65 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. REF65 is a member of ABB s Relion protection and control product family and its 65 series. The 65 series IEDs are characterized by their compactness and withdrawableunit design. Reengineered from the ground up, the new 65 series has been designed to unleash the full potential of the IEC 6850 standard for communication and interoperability of substation automation devices. Application REF65 provides feeder overcurrent and earthfault protection for distribution networks, including substation busbar protection applying the reverse interlocking principle, or GOOSE messaging over a switched Ethernet station bus. REF65 fits both isolated neutral networks and networks with resistance or impedance earthed neutrals. Furthermore, making use of the IED s advanced interstation communication facilities, REF65 can also be applied for protection of ringtype 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 REF65 is available in nine predefined standard configurations to suit the most common feeder protection and control applications. Protection and control REF65 offers directional and nondirectional overcurrent and earthfault protection and thermal overload protection. Some standard configurations allow as an option admittancebased, harmonicsbased or wattmetricbased earthfault protection to be used in addition to directional earthfault protection. The admittancebased earthfault 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, REF65 features sensitive earthfault protection, phase discontinuity protection, transient/intermittent earthfault protection, phase overvoltage, undervoltage and residual overvoltage protection, positive phasesequence undervoltage and negativephase sequence overvoltage protection. Overfrequency, underfrequency and frequency gradientbased protection is offered in standard configurations H and J. The IED also incorporates optional autoreclose 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 metalenclosed, airinsulated 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 multilayer logic by combining function blocks along with timers and flipflops. By combining protection and logic functions the IED can be modified to fit the requirements of the application. REF65 integrates functionality for the control of a circuitbreaker via the front panel HMI or by means of remote controls. REF65 also features two control blocks which are intended for motoroperated control of disconnectors or circuit breaker trucks and for their position indications. Further, REF65 offers a control block which is intended for motoroperated 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 support The standard configuration G includes one conventional residual current (I 0 ) input and three sensor inputs for the connection of three combisensors with RJ5 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 combisensors, separate current and voltage sensors with adapters can be used. Standardized communication REF65 features genuine support for the IEC 6850 standard for interdevice communication in substations. It also supports the DNP protocol, the IEC 6087050 protocol, and the industry standard Modbus protocol. For a selfhealing Ethernet solution the IED offers an optional fibreoptic 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 6850 station bus inside of a switchgear bay. The selfhealing Feeder protection and control REF65

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 selfhealing Ethernet ring can be built on the Ethernet based IEC 6850, Modbus and DNP protocols. The implementation of the IEC 6850 standard in REF65 covers both vertical and horizontal communication, including GOOSE messaging with binary and analog signals and parameter setting according to IEC 68508. For timecritical applications REF65 supports synchronization over Ethernet using SNTP or over a separate bus using IRIGB. Preventive condition monitoring For continuous control of its operational availability REF65 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 diagram The 65 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 webbrowser based HMI. The default SLD can be modified according to user needs using the graphical display editor of PCM600. REF65 Feeder protection and control
