Section 2 REU615 overview
2.1 OverviewThe voltage protection and control IED, REU615 is available in two standard
configurations, denoted A and B. Configuration A is preadapted for voltage and
frequency-based protection schemes in utility and industrial power systems and
distribution systems including networks with distributed power generation. The B
configuration is designed for automatic voltage regulation of power transformers
equipped with an on-load tap-changer. Both configurations also feature additional
CB control, measuring and supervising functions. REU615 is a member of ABBs
Relion product family and part of its 615 protection and control product series.
The 615 series IEDs are characterized by their compactness and withdrawableunit
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 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.

2.7 CommunicationThe IED supports a range of communication protocols including IEC 61850, IEC
60870-5-103, Modbus and DNP3. Operational information and controls are
available through these protocols. However, some communication functionality,
for example, horizontal communication between the IEDs, is only enabled by the
IEC 61850 communication protocol.
The IEC 61850 communication implementation supports all monitoring and
control functions. Additionally, parameter settings, disturbance recordings and
fault records can be accessed using the IEC 61850 protocol. Disturbance recordings
are available to any Ethernet-based application in the standard COMTRADE file
format. The IED can send and receive binary signals from other IEDs (so calledhorizontal communication) using the IEC61850-8-1 GOOSE profile, where the
highest performance class with a total transmission time of 3 ms is supported.
Further, the IED supports sending and receiving of analog values using GOOSE
messaging. The IED meets the GOOSE performance requirements for tripping
applications in distribution substations, as defined by the IEC 61850 standard. The
IED can simultaneously report events to five different clients on the station bus.
The IED can support five simultaneous clients. If PCM600 reserves one client
connection, only four client connections are left, for example, for IEC 61850 and
Modbus.

Section 3 REU615 standard configurations
3.1 Standard configurationsREU615 is available in two standard configurations. The standard signal
configuration can be altered by means of the graphical signal matrix or the optional
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 IED configuration can be adapted to user-specific application
requirements.

3.3 Presentation of standard configurationsFunctional diagramsThe functional diagrams describe the IED's functionality from the protection,
measuring, condition monitoring, disturbance recording, control and interlocking
perspective. Diagrams show the default functionality with simple symbol logics

forming principle diagrams. The external connections to primary devices are also
shown, stating the default connections to measuring transformers. The positive
measuring direction of directional protection functions is towards the outgoing feeder.
The functional diagrams are divided into sections with each section constitutingone functional entity. The external connections are also divided into sections. Only
the relevant connections for a particular functional entity are presented in each
section.
Protection function blocks are part of the functional diagram. They are identified
based on their IEC 61850 name but the IEC based symbol and the ANSI function
number are also included. Some function blocks, such as PHHPTOC, are used
several times in the configuration. To separate the blocks from each other, the IEC
61850 name, IEC symbol and ANSI function number are appended with a running
number, that is an instance number, from one upwards. If the block has no suffix
after the IEC or ANSI symbol, the function block has been used, that is,instantiated, only once. The IEDs internal functionality and the external
connections are separated with a dashed line presenting the IEDs physical casing.
Signal Matrix and Application ConfigurationWith Signal Matrix and Application Configuration in PCM600, it is possible to
modify the standard configuration according to the actual needs. The IED 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. The Signal Matrix is used for GOOSE signal input engineering and
for making cross-references between the physical I/O signals and the function
blocks. The Signal Matrix tool cannot be used for adding or removing functionblocks, for example, GOOSE receive function blocks. The Application
Configuration tool is used for these kind of operations. If a function block is
removed with Application Configuration, the function related data disappears from
the menus as well as from the 61850 data model, with the exception of some basic
function blocks, which are mandatory and thus cannot be removed from the IED
configuration by removing them from the Application Configuration.
3.4 Standard configuration A3.4.1 Applications
The standard configuration is intended for voltage protection and synchronism
check in medium voltage networks. The standard configuration handles fault
conditions originating from abnormal voltages in the power system. Also the
synchronism and energizing check can be handled for two galvanically
interconnected networks.
The IED with a standard configuration is delivered from the factory with default
settings and parameters. The end-user flexibility for incoming, outgoing and

Additionally, all the digital inputs that are connected by default are also enabled
with the setting. Default triggering settings are selected depending on the
connected input signal type. Typically all protection START signals are selected to
trigger the disturbance recorded by default.
3.4.3 Functional diagramsThe functional diagrams describe the default input, output, alarm LED and function-
to-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements, if necessary.
The analog channels, measurements from voltage transformers, have fixed
connections towards the different function blocks inside the IEDs standard
configuration. Exceptions from this rule are the eight analog channels available for
the disturbance recorder function. These channels are freely selectable and a part of
the disturbance recorders parameter settings.
The analog channels are assigned to different functions. The common signal
marked with 3U represents the three phase voltages. The signal marked with Uorepresents the measured residual voltage via open-delta connected voltage
transformers.

phase non-directional overcurrent protection, three-phase under and overvoltage
protection. The IED also incorporates a thermal overload protection function,
which supervises the thermal stress of the transformer windings to prevent
premature aging of the winding's insulation.
The RTD/mA input module is optional in the standard configuration. When using
the RTD/mA input module it is possible to have the tap changer position indication
as an mA signal, ambient temperature of the power transformer can be used in
thermal protection and the multi-purpose protection functions are available. The
multi-purpose protection function enables protection based on analog values from
the IEDs RTD/mA input module, or from other IEDs using analog horizontal
GOOSE messaging.
The IED with a standard configuration is delivered from the factory with default
settings and parameters. The end-user flexibility for incoming, outgoing and

to-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements, if necessary.
The analog channels, measurements from current transformers and voltagetransformers, have fixed connections towards the different function blocks inside
the IEDs standard configuration. Exceptions from this rule are the eight analog
channels available for the disturbance recorder function. These channels are freely
selectable and a part of the disturbance recorders parameter settings.
The analog channels are assigned to different functions. The common signal
marked with 3I represents the three phase currents and 3U represents the three
phase voltages. The signal marked with Uo represents the measured residual
voltage via open-delta connected voltage transformers. The signal marked with Io
represents the measured residual current, via a sum connection of second current
transformer cores of the phase current transformers.

Section 4 Requirements for measurementtransformers
4.1 Current transformers4.1.1 Current transformer requirements for non-directionalovercurrent protection
For reliable and correct operation of the overcurrent protection, the CT has to bechosen carefully. The distortion of the secondary current of a saturated CT may
endanger the operation, selectivity, and co-ordination of protection. However,
when the CT is correctly selected, a fast and reliable short circuit protection can be
enabled.
The selection of a CT depends not only on the CT specifications but also on the
network fault current magnitude, desired protection objectives, and the actual CT
burden. The protection settings of the IED should be defined in accordance with
the CT performance as well as other factors.
4.1.1.1 Current transformer accuracy class and accuracy limit factorThe rated accuracy limit factor (Fn) is the ratio of the rated accuracy limit primary
current to the rated primary current. For example, a protective current transformer
of type 5P10 has the accuracy class 5P and the accuracy limit factor 10. For
protective current transformers, the accuracy class is designed by the highest
permissible percentage composite error at the rated accuracy limit primary current
prescribed for the accuracy class concerned, followed by the letter "P" (meaning
protection).

rated primarycurrent (%)Phase displacement at rated primarycurrent
Composite error atrated accuracy limitprimary current (%)inutes centiradians
5P 1 60 1.8 5
10P 3 - - 10
The accuracy classes 5P and 10P are both suitable for non-directional overcurrent
protection. The 5P class provides a better accuracy. This should be noted also if
there are accuracy requirements for the metering functions (current metering,
power metering, and so on) of the IED.

The CT accuracy primary limit current describes the highest fault current
magnitude at which the CT fulfils the specified accuracy. Beyond this level, the
secondary current of the CT is distorted and it might have severe effects on the
performance of the protection IED.
In practise, the actual accuracy limit factor (Fa) differs from the rated accuracy
limit factor (Fn) and is proportional to the ratio of the rated CT burden and the
actual CT burden.
The actual accuracy limit factor is calculated using the formula:

A071141 V1 EN
Fn the accuracy limit factor with the nominal external burden Sn
Sin the internal secondary burden of the CT

4.1.1.2 Non-directional overcurrent protectionThe current transformer selection
Non-directional overcurrent protection does not set high requirements on the
accuracy class or on the actual accuracy limit factor (Fa) of the CTs. It is, however,recommended to select a CT with Fa of at least 20.
The nominal primary current I1n should be chosen in such a way that the thermal
and dynamic strength of the current measuring input of the IED is not exceeded.
This is always fulfilled when
I1n > Ikmax / 100,
Ikmax is the highest fault current.
The saturation of the CT protects the measuring circuit and the current input of the
IED. For that reason, in practice, even a few times smaller nominal primary current
can be used than given by the formula.
Recommended start current settingsIf Ikmin is the lowest primary current at which the highest set overcurrent stage is to
operate, the start current should be set using the formula:
Current start value < 0.7 x (Ikmin / I1n)
I1n is the nominal primary current of the CT.
Section 4 1MRS757054 CRequirements for measurement transformers
60 REU615Application Manual

7/27/2019 ABB Reles de Frecuencia
67/80
The factor 0.7 takes into account the protection IED inaccuracy, current
transformer errors, and imperfections of the short circuit calculations.
The adequate performance of the CT should be checked when the setting of the
high set stage overcurrent protection is defined. The operate time delay caused bythe CT saturation is typically small enough when the overcurrent setting is
noticeably lower than Fa.
When defining the setting values for the low set stages, the saturation of the CT
does not need to be taken into account and the start current setting is simply
according to the formula.
Delay in operation caused by saturation of current transformersThe saturation of CT may cause a delayed IED operation. To ensure the time
selectivity, the delay must be taken into account when setting the operate times of
successive IEDs.
With definite time mode of operation, the saturation of CT may cause a delay that
is as long as the time the constant of the DC component of the fault current, when
the current is only slightly higher than the starting current. This depends on the
accuracy limit factor of the CT, on the remanence flux of the core of the CT, and
on the operate time setting.
With inverse time mode of operation, the delay should always be considered as
being as long as the time constant of the DC component.
With inverse time mode of operation and when the high-set stages are not used, the
AC component of the fault current should not saturate the CT less than 20 times thestarting current. Otherwise, the inverse operation time can be further prolonged.
Therefore, the accuracy limit factor Fa should be chosen using the formula:
Fa > 20*Current start value / I1n
The Current start value is the primary pickup current setting of the IED.
4.1.1.3 Example for non-directional overcurrent protectionThe following figure describes a typical medium voltage feeder. The protection isimplemented as three-stage definite time non-directional overcurrent protection.

Figure 34: Example of three-stage overcurrent protection
The maximum three-phase fault current is 41.7 kA and the minimum three-phase
short circuit current is 22.8 kA. The actual accuracy limit factor of the CT is
calculated to be 59.
The start current setting for low-set stage (3I>) is selected to be about twice the
nominal current of the cable. The operate time is selected so that it is selective with
the next IED (not visible in the figure above). The settings for the high-set stage
and instantaneous stage are defined also so that grading is ensured with the
downstream protection. In addition, the start current settings have to be defined sothat the IED operates with the minimum fault current and it does not operate with
the maximum load current. The settings for all three stages are as in the figure above.
For the application point of view, the suitable setting for instantaneous stage (I>>>)
in this example is 3 500 A (5.83 x I2n). For the CT characteristics point of view, the
criteria given by the current transformer selection formula is fulfilled and also the
IED setting is considerably below the Fa. In this application, the CT rated burden
could have been selected much lower than 10 VA for economical reasons.
