1 Relion 65 series Line differential protection and control RED65 Compact and versatile solution for utility and industrial power distribution systems

2 Ideal selectivity for twoend line differential protection RED65 is a phasesegregated, twoend line differential protection and control relay for protection, control, measurement and supervision in utility and industrial power distribution systems, including radial, looped and meshed distribution networks, with or without distributed power generation. RED65 is also ideal for line differential applications with an inzone transformer. RED65 relays communicate between substations either over a fiberoptic link or a galvanic pilot wire connection. pplication RED65 has been designed to be the main protection for overhead line and cable feeders, in either isolated neutral, resistanceearthed, compensated or effectively earthed distribution networks, depending on the standard configuration. RED65 is available in five standard configurations, one of which is a plain line differential protection with overcurrent backup protection two with added earthfault protection functionality in particular, and another two further extended with directional overcurrent as well as phasevoltage and frequencybased protection. Switch on to fault is now introduced in all standard configurations and voltage unbalance in the two extended ones. They both also include a fault locator which locates short circuits in radial distribution networks and earth faults in effectively and lowresistance earthed ones. If the fault current is as high as or higher than the load current, earth faults in isolated neutral distribution networks will also be located. In addition, one of the two extended standard configurations includes support for three combisensor inputs for phase currents (Rogowski coil) and voltages (voltage divider), whereas the other supports conventional current and voltage instrument transformers as the rest of the standard configurations. Two RED65 relays interconnected over a communication link form an entirely selective unit protection scheme. Protection of ringtype and meshed distribution networks generally requires unit protection solutions, also applied in radial networks containing distributed power generation. The standard configurations can be tailored to meet applicationspecific requirements using the IEC 6850 compliant Protection and Control IED Manager PCM600. Humanmachine interface s a member of the Relion product family, RED65 shares the same humanmachine interface (HMI) look and feel as the other Relion protection and control relays and IEDs. The same look and feel includes the location of a push button with a certain function and the menu structure. RED65 is equipped with a large graphical display which can show customizable singleline diagrams (SLD) with position indication for the circuit breaker, disconnectors and the earthing switch. lso 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 browserbased HMI that has now been enriched with a number of usability enhancing features. Standardized communication RED65 fully supports the IEC 6850 standard for communication and interoperability of substation automation devices, including fast GOOSE messaging and now also IEC LE and Edition, offering substantial benefits in terms of extended interoperability. The line differential relay further supports the DNP, IEC and Modbus protocols, now introducing also the parallel redundancy protocol (PRP) and the highavailability seamless redundancy (HSR) protocol. With the protocol adapter SPZC 0, Profibus DVP can also be used. RED65 is able to use two communication protocols simultaneously. For redundant Ethernet communication, RED65 offers two optical Ethernet network interfaces. The redundant Ethernet solution can be built on the Ethernetbased IEC 6850, Modbus and DNP protocols. The implementation of the IEC 6850 standard in RED65 covers both vertical and horizontal communication, including GOOSE messaging with both binary and analog signals as well as parameter setting according to IEC In addition, IEC LE process bus with sending sampled values of both analog voltages and currents and receiving sampled values of voltages is introduced. The sampled values can also be used for synchrocheck, both in conventional instrument transformer and sensorbased applications, to ensure safe interconnection of two networks. For process bus applications, which require highaccuracy time synchronization, IEEE 588 V is used, with a time stamp resolution of not more than four microseconds. IEEE 588 V is supported in all variants with a redundant Ethernet communication module. In addition, RED65 supports synchronization over Ethernet using SNTP or over a separate bus using IRIGB.
