Overview
REG615 is a dedicated generator and interconnection protection relay designed for
the different power generation applications. REG615 is available in three standard
configurations denoted A, C and D. Standard configuration A is intended for the
interconnection protection, control, measurement and supervision of the common
point of coupling distributed power generation into the utility network. Standard
configurations C and D are designed for the protection, control, measurement and
supervision of small or medium size generators used in diesel, gas, hydroelectric,
combined heat and power (CHP), and steam power plants. REG615 is a member of
ABB’s Relion
®
product family and part of its 615 protection and control product
series. The 615 series protection relays are characterized by their compactness and
withdrawable unit design.
Re-engineered from the ground up, the 615 series has been designed to unleash the full
potential of the IEC 61850 standard for communication and interoperability between
substation automation devices. Once the standard configuration relay has been given
the application-specific settings, it can directly be put into service.
The generator protection relay provides main protection for small size power
generators. The generator protection relay is also used as back-up protection for
medium size generators in power applications, where an independent and redundant
protection system is required. The interconnection protection relay provides main
protection fulfilling the grid codes to connect distributed generation with the power
grid.
The 615 series relays support a range of communication protocols including IEC
61850 with Edition 2 support, process bus according to IEC 61850-9-2 LE, IEC
60870-5-103, Modbus
®
and DNP3. Profibus DPV1 communication protocol is
supported by using the protocol converter SPA-ZC 302.
