Parameter

Value type

Default

Definition

IED Name

Name

IED Name to be

used as part of the

61850 addressing of

the data.

AP Name

S1

Access point name,

used to refer to the

communication

interface of this

device in the SCL

file.

Delete dynamic

datasets

-/

Deletes all dynamic

data sets that may

have been created

by client tools and

stored in the

device’s memory.

Remove not valid

LNs

-/

Removes from the

data maps logical

nodes that are not

pertinent for this

device type.

Instantiated RCBs

Yes/No

No

"No" (default): there

are 8 separately

defined BRCBs and

8 separately defined

URCBs in the ICD

file.

"Yes": the report

control blocks are

instantiated from

single BRCB and

URCB definitions

given in the ICD file.

ResvTms included in

BRCBs

Yes/No

Specifies whether

the "ResvTms"

attribute is included

in the BRCBs or not

(this is actually an

extension of Tissue

453 and Edition 2

and should be set to

"No" if the client

system does not

support this).

Owner included in

RCBs

Yes/No

Parameter

Value type

Default

Definition

Control mode for

object nodes

DirNorSec

Selects the control

model to be used

with the controllable

objects.

SDO allowed in DS

Yes/No

"Yes": the

"Structured Data

Objects", e.g.

A.phsA, are allowed

in pre-defined data

sets DS1, DS2, DS3.

"No": the "Structured

Data Objects" are

not allowed in pre-

defined data sets.

Set to "No" if the

client system is able

to handle only

complete 3-phase

data types like A,

PhV, PPV.

Type of BRC

32/64/128 BIT

Length of binary

counters.

Type of SBO

VisStr64/VisStr65

Used to select the

length of visible

strings.

Size of array

Number

Number of elements

in the arrays used to

transfer the

harmonics.

LLN

0

 and LPHD Dos

in datasets

Yes/No

No

Can be used to

include LLN0 and

LPHD in predefined

data sets DS1, DS2,

DS3.

3.2. Selecting the logical nodes and data sets for event reporting

Logical nodes may appear or hide in the data maps of devices that can be set to

different protection modes (motor, generator, or feeder). Therefore, it is

recommended to set the required protection functions for the devices before

configuring the IEC-61850 protocol.

NOTE: The data maps may contain logical nodes that are not functional in the

device that is being configured. See the device’s manual for information on

what functions are really operational in the device type being configured.

1. Go to IEC 61850 data map (x).

2. Set the In use field of the needed logical nodes to Yes.

3. Select to which pre-defined data set the data from the given function is

assigned (for example for reporting purposes): set Dataset x to Yes.

NOTE: If there is no special reason to use many data sets, use only data

set 1.

3.3. Data sets

Data sets are assigned to report control blocks in the IEC 61850 BRCB

configuration and IEC 61850 URCB configuration setting views. An Easergy

P3 device has three predefined data sets (DS1, DS2 and DS3) that can be

assigned to one or more of the eight buffered report control blocks (BRCB 1–8)

and to one or more of the eight unbuffered report control blocks (URCB 1–8).

Some clients may create their own, so-called dynamic data sets and assign them

to report control blocks. Both persistent and non-persistent dynamic data sets are

supported. They can be viewed with Easergy Pro. IEC 61850 client tool software

is needed for creating them.

3.4. Defining the measurement configuration settings

You can configure the deadband values, deadband integration time and unit

multipliers used by the IEC 61850 protocol in the Communication > IEC 61850

Measurement Config setting view in Easergy Pro.

•

There are two variants of the deadband calculation: absolute deadband and

integrated deadband. To select absolute deadband, set the Deadband

integration time to zero.

•

Set the deadband values with caution. Too small values may cause

unnecessary overhead in the data transfer.

Example: If the Current I deadband value is set to 5 A and Integration

time is set to 0 (absolute deadband), the change condition is satisfied

when the value changes more than 5 A from the previously reported

value. If, on the other hand, the integration time is set to 1, the change

condition is satisfied for instance if the signal value changes more than 1

A from the previously reported value and remains at that level for five

seconds.
