1. Description

RED615 is a phase-segregated two-end line

differential protection and control IED (intelligent

electronic device) designed for utility and

industrial power systems, including radial, looped

and meshed distribution networks with or without

distributed power generation. The RED615s

communicate between substations over a fibre-

optic link or a galvanic pilot wire connection.

RED615 is a member of ABB’s Relion® product

family and part of its 615 protection and control

product series. The 615 series IEDs are

characterized by their compactness and

withdrawable-unit design. Re-engineered from the

ground up, the 615 series has been guided by the

IEC 61850 standard for communication and

interoperability of substation automation

equipment.

The IED provides unit type main protection for

overhead lines and cable feeders in distribution

networks. The IED also features current-based

protection functions for remote back-up for down-

stream protection IEDs and local back-up for the

line differential main protection. Further, standard

configurations B and C also include earth-fault

protection.

The IED is adapted for the protection of overhead

line and cable feeders in isolated neutral,

resistance earthed, compensated (impedance

earthed) and solidly earthed networks. Once the

IED has been given the application-specific

settings, it can directly be put into service.

The 615 series IEDs support a range of

communication protocols including IEC 61850

with GOOSE messaging, IEC 60870-5-103,

Modbus® and DNP3.

2. Standard configurations

RED615 is available in three alternative standard

configurations. The standard signal configuration

can be altered by means of the graphical 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 utilizing various logical elements

including timers and flip-flops. By combining

protection functions with logic function blocks the

IED configuration can be adapted to user specific

application requirements.

1) The instances of a protection function represent the number of identical function blocks available in a standard configuration. By setting the

application specific parameters of an instance, a protection function stage can be established.

2) One of the following can be ordered as an option; Admittance based E/F, Wattmetric based E/F or Harmonics based E/F. The option is an addition to

the existing E/F of the original configuration. The Admittance based and Wattmetric based optional E/F has also a predefined configuration in the

relay. The optional E/F can be set on or off.

3) Io selectable by parameter, Io measured as default.

4) Uo measured is always used.

5) Io measured is always used.

6) Available in IED and SMT but not connected to anything in logic.

7) Io selectable by parameter, Io calculated as default.

8) Io calculated is always used.

3. Protection functions

The IED offers two-stage phase-segregated line

differential protection, phase overcurrent

protection, negative phase-sequence overcurrent

protection and circuit-breaker failure protection.

Depending on the standard configuration chosen,

the basic functionality can be extended by

thermal overload protection, directional or non-

directional earth-fault protection, sensitive earth-

fault protection, phase discontinuity protection,

transient/intermittent earth-fault protection,

residual overvoltage protection and three-pole

multi-shot auto-reclose functions for overhead

line feeders. For standard configuration B

admittance-based, wattmetric-based or

harmonics-based earth-fault protection, is offered

as an option in addition to the directional earth-

fault protection.

The line differential protection function includes a

stabilized low stage and an instantaneous high

stage. The stabilized low stage provides sensitive

differential protection and remains stable during,

for example, current transformer saturation

conditions. The low-stage operation can be

restrained using second harmonic detection if an

out-of-zone power transformer is to be energized.

The instantaneous high stage offers less sensitive

differential protection but enables fast operation

during high fault currents.

The operating time characteristic for the low

stage can be set to definite time or inverse

definite time mode. The direct inter-trip function

ensures that both ends are always simultaneously

tripped, independent of the fault current

contribution.

4. Application

RED615 can be used in a variety of applications

requiring an absolutely selective unit type

protection system. The zone-of-protection of a

line differential protection system is the feeder

section defined by the location of the current

transformers in the local and the remote

substation.

Combining horizontal GOOSE communication

over a station bus and binary signal transfer over

the protection communication link offers new

application possibilities beyond traditional line

differential protection. One interesting application

based on inter-substation signal transfer is loss-of-

mains (LOM) protection in networks with

distributed generation. The performance of the

combination of binary signal transfer and

horizontal GOOSE communication performance

as to speed, selectivity and reliability are hard to

match with conventional loss-of-mains protection.

RED615 is the ideal IED for the protection of

feeders in network configurations containing

closed loops. Under normal operating conditions

the feeder loop is closed. The aim of the closed

loop is to secure the availability of power for the

end users. As a result of the closed loop

configuration, any fault spot in the system will be

fed with fault current from two directions. Using

plain overcurrent protection, either directional or

non-directional, it is difficult to obtain fast and

selective short circuit protection. With RED615

line differential protection IEDs the faulty part of

the network can be selectively isolated, thus

securing power distribution to the healthy part of

the network.

Figure 4. Closed loop network configuration with RED615 line differential protection and control IEDs

Under certain operational circumstances, such as

maintenance of primary equipment or substation

extension projects there will be a need for

interconnecting network parts, which normally are

separated. To avoid major re-parameterization of

the protection devices of the network when the

network topology is changed, line differential

protection IEDs can be used to obtain absolutely

selective feeder protection in looped networks.
