Generator and Interconnection Protection
REG615
Product version: 5.0 FP1

1. Description

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
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.

product family and part of its 615
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.

2. Standard configurations

REG615 is available in three alternative standard
configurations. The standard signal configuration can be
altered by means of the signal matrix or the graphical
application functionality of the Protection and Control IED
Manager PCM600. Further, the application configuration
functionality of PCM600 supports the creation of multi-layer
logic functions using various logical elements, including timers
and flip-flops. By combining protection functions with logic
function blocks, the relay configuration can be adapted to user-
specific application requirements.
The protection relay is delivered from the factory with default
connections described in the functional diagrams for binary
inputs, binary outputs, function-to-function connections and
alarm LEDs. Some of the supported functions in REG615 must
be added with the Application Configuration tool to be available
in the Signal Matrix tool and in the relay. The positive measuring
direction of directional protection functions is towards the
busbar.
