Generator and interconnection protection REG615 IEC

Compact generator and extensive interconnection protection for power generation

REG615 is a dedicated generator and interconnection protection relay for protection, control, measurement and supervision of power generators and interconnection points of distributed generation units in utility and industrial power distribution system.  

REG615 is available in three standard configuration, two of which have been exclusively designed for generator applications and one for interconnection applications. As generator protection, REG615 offers full protection both during start-up and normal run for both the generator and the prime mover, typically in small and medium-sized diesel, gas, hydroelectric and combined heat and power plants.

As interconnection protection, REG615 commits to ensuring a stable and reliable grid at times when distributed generation units being directly connected to the grid are growing in both size and number. REG615 is continuously monitoring distributed generation units such as solar or wind farms, both to determine whether and when to disconnect them from the grid as well as to detect islanding from the grid. 

REG615 fully supports the IEC 61850 standard for communication and interoperability of substation automation devices, including IEC 61850-9-2 LE and Edition 2, offering substantial benefits in terms of extended interoperability. REG615 further supports both the parallel redundancy protocol (PRP) and the high-availability seamless redundancy (HSR) protocol, together with the DNP3, IEC 60870-5-103 and Modbus® protocols. With the protocol adapter SPA-ZC 302, Profibus DPV1 can also be used.   

REG615 is a member of ABB’s Relion® product family and part of its 615 protection and control series of relays.
