FOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.

2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.

3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accepted by the National Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

This CDV of the International Standard IEC 61850-7-4 has been prepared by working groups10, 11 and 12 of IEC technical committee 57.

Recipients of this document are invited to submit, with their comments, notification ofany relevant patent rights of which they are aware and to provide supportingdocumentation.

INTRODUCTION

This document is part of a set of specifications, which details a layered substationcommunication architecture. This architecture has been chosen to provide abstract definitionsof classes and services such that the specifications are independent of specific protocolstacks, implementations, and operating systems. The mapping of these abstract classes andservices to communication stacks is outside the scope of part 7-x and may be found in part 8-xand 9-x.

IEC 61850-7-1 gives an overview of this communication architecture. The part IEC 61850-7-3defines common attribute types and common data classes related to substation applications.The attributes of the common data classes may be accessed using services defined in IEC61850-7-2.These common data classes are used in part IEC 61850-7-4 to define thecompatible data classes.

To reach interoperability all data to be exchanged need a strong definition with regard tosyntax and semantic. The semantic of the data is mainly provided by the part IEC 61850-7-4.

It should be noted that data with full semantic do not provide interoperability by itself.Compatible, domain specific services (see IEC 61850-7-2) are needed as well. Since data andservices are hosted by devices (IED) a proper device model is needed also.

The compatible logical node class definitions and data class definitions found in this part areabstract definitions and shall be finally mapped into concrete object definitions that are to beused for a particular protocol e.g. MMS (ISO 9506).

61850-7-4/Ed.1 CDV IEC:2001 - 8 - 57/xx/CDV



1 Scope

This part of IEC 61850 specifies the information model of devices and functions related tosubstation applications. In particular, it specifies the compatible logical node names and datanames for communication between Intelligent Electronic Devices. This includes therelationship between logical nodes and data.

The logical node classes and data classes defined in this document are part of the classmodel introduced in IEC 61850-7-2. The names defined in this document are used to build thehierarchical object references applied for communicating with IEDs in substations and ondistribution feeders.

The rules for building system-wide unambiguous object references are defined in IEC 61850-7-1, IEC 61850-7-2, and 61850-6.

To avoid private, incompatible extension rules this part IEC 61850-7-4 specifies naming rulesfor extensions of logical node classes and data classes.

• Annex A (informative) gives examples for multiple instances of logical node classes by useof the LN-Instance-ID;

• Annex B (normative) gives the rules for creating new logical node classes and dataclasses.

NOTE This part does not provide tutorial material. It is recommended to read IEC 61850-7-1 in conjunction withpart 61850-7-3, and -7-2. Additionally it is recommended to read the part IEC 61850-5 first. This part does alsonot discuss implementation issues.

This standard is applicable to describe device models and functions of substations and feederequipment. This information may also be applied to describe device model and functions for

• substation to substation information exchange,

• substation to control centre information exchange,

• power plant to control centre information exchange,

• information exchange for distributed generation,

• information exchange for distributed automation, or

• information exchange for metering.

In this clause, the system specific information is defined. This includes basic logical nodeinformation (e.g. logical node mode control, nameplate information, operation counters) as wellas information related to the physical device implementing the logical devices and logicalnodes.

Some of this information is used in each logical node. For that purpose, a basic LN is specified.The other logical nodes are specializations of the basic LN as shown in Figure 1. Other systeminformation is specific for a logical device or a physical device. This information is included inthe logical nodes LLN0 and LPHD (for details about the relations between physical devices,logical devices, LLN0 and LPHD see part 7-2 of this standard).

5.4 Logical Nodes for Protection Functions LN Group: P

5.4.1 Overview

LN names for protection start with: P

NOTE:

1. If there are several stages of one function (i.e. Multi zone relay), each stage is a separateinstantiation of the LN model.

2. This list is derived from Part 5, however for modelling purposes some logical nodes havebeen separated - the frequency and others in two - one for under and one for over, is to make itconsistent with the existing under/over current and under/over voltage elements. Since theprefix and suffix (comprising the wrapper) are used for other purposes, we should be able todistinguish by the name of the Logical Node if it is an under or over function.

3. Other logical nodes have been added to model complex protection devices and schemes.4. A number of Logical Node requirements from IEC 61850-5 are met by using combinations of the

LNs found in this section as follows:

• Under-excitation (PUEX) is covered by PDUP.

• Reverse phase or phase balance current relay (PPBR) is covered by PTOC withthree phase information and processing, and PDIR with sequence current as aninput or even ration of negative and positive sequence currents.

• Phase sequence or phase balance voltage relay (PPBV) is covered by PTOV withthree phase information and processing.

• Over excitation (POEX) is covered by PVPH.

• Voltage and current balance relay (PVCB) functionality is provided by combinationsof PTOV, PTUV, and PDIR, with three-phase information and processing.

• DC over voltage relay (PDOV) is covered by PTOV both for AC and DC.

• Rotor earth faults (PREF), stator earth faults (PSEF), and interturn fault (PITF) arecovered by PTOC.

• Directional overcurrent (PDOC) is covered by the combination of PTOC and PDIR.

• Directional earth fault (PDEF) See IEC 61850-5. For application use forcompensated networks, see Annex C.

• DC time overcurrent (PDCO) is covered by PTOC both for AC and DC.

Annex A(informative)

Instantiation of LNs by use of the LN-Instance

The LN-Instance-ID is required when multiple logical node instances of one Logical Node classexist in one logical device. By help of these Instance-IDs the object name may be definedplausible and unique.

NOTE - Object naming rules are defined in 61850-7-2.

The Instance-IDs shall be defined by use of the enumeration. The following examples illustratethe use of Instance-ID

Logical Node Name: YPTR (Power transformer)

Instance LN Object Name(without LN-Prefix)

1 YPTR1 Transformer unit phase L1



4 YPTR4 Transformer unit in reserve

Logical Node Name: ZAXN (Auxiliary network)

Annex B(normative)

Rules for creating extended private names

B.1 Logical Node extensions

A private Logical Node Name shall be created by use of the following naming conventions:

• E as the first character with the meaning “extension”;

• The second character shall be chosen in accordance with the relevant prefix of the LNG.

• The third and fourth characters shall be defined as an abbreviation of the English name ofthe new LN Name.

Examples:

Normally an automatic cooling control shall be modelled in accordance with this part of IEC61850 by use of the generic LN “Automatic Process Control” GAPC (Sub clause 5.7.1). But ifthere is a need for creating an special private LN, so the LN Name shall be

E A C C

Extended Automatic control Cooling Control

As an example, a fire protection LN Name would be created in the same manner as

E Z F P

Extended Further equipment Fire Protection

B.2 Data object extensions

When the standard data classes do not cover all of the data objects to meet modelling needsfor implementing a specific Intelligent Electronic Device, a “private” data object may be createdby the implementers. A private Data Object shall be created by the following rules:

• Allocation of the applicable Common Data Class (defined in 61850-7-3);

• Assignment to the applicable Common Data Class in accordance with part 7-3 of IEC61850;

61850-7-4/Ed.1 CDV IEC:2001 - 77 - 57/xx/CDV

• Assignment of the Data Name with

- prefix Ex for marking the Data as extended,

- up to 7 further characters as an abbreviation of the English name of the Data . Standardabbreviations must be used where available.

Example: Colour of transformer oil

Common Data Class: Integer Status (ISI)

Data Object Group: Status

Data Name: ExColTrO

B.3 General rules

The creator of extended private Names shall ensure that each additional name is unique andconsistent in the substation automation system considered.

The description of the extended Name shall be added to the IEC documentation of the providerspecific system or customer specific project.

Annex C(Informative)

Modelling Examples

This annex includes informative modelling examples.

C.1 Use of PTEF and PDEF

PTEF (Protection Transient Earth Fault) and PDEF (Protection Directional Earth Fault) aretypically used functions to detect the location of an earth fault in a compensated network. ThePTEF detects the transient charging current related with the network capacitance. Thereforethe PTEF can only detect the beginning of an earth fault. The PDEF detects the residual phaseto earth current. Therefore the PDEF is able to notify the beginning and the end of an earthfault.

Figure 2 - Fault current IF in a compensated network with earth fault

The feeders of the faulty line will indicate a foreward earthfault while the other feeders mayindicate a reverse earthfault. The directional information is modelled using the PDIR(Protection Directional Element) logical node. The related data objects are e.g.:

at the beginning of the earth fault:

- PTEF.Start (The data attribute stval – see 7-3 – changes from FALSE to TRUE.)

- PDIR.Fltfwd (The data attribute stval – see 7-3 – changes from FALSE to TRUE.)

or

- PDEF.Start (The data attribute stval – see 7-3 – changes from FALSE to TRUE.)

- PDIR.Fltfwd (The data attribute stval – see 7-3 – changes from FALSE to TRUE.)

61850-7-4/Ed.1 CDV IEC:2001 - 79 - 57/xx/CDV

at the end of the earth fault:

- PDEF.Start (The data attribute stval – see 7-3 – changes from TRUE to FALSE.)

- PDIR.Fltfwd (The data attribute stval – see 7-3 – changes from TRUE to FALSE.)

C.2 PSCH

The PSCH logical node is used for modeling typical schemes in multifunctional IEDs. The dataobjects allow its use for modeling of different communications based accelerating schemes fortransmission line protection.

It also can be used for modeling of physical or virtual inputs and outputs of the IED.

One instance of PSCH corresponds to one physical or virtual input or output.

Logical Nodes mapped into the PSCH can be located in different Logical Devices. PSCHinterfaces with several logical nodes (PDIS, PDIR, RCPW etc.) PSCH output gets mapped intoa bitpair of a GOOSE message for transmission.

For example, in a Permissive Overreaching Scheme, the IED will have an overreachingdistance element PDISx or a directional element PDIRx send a Carrier Send signal to theremote end of the protected line through a communications IED. Either the PDISx or thePDIRx is mapped to a PSCHx that is mapped to a bit pair of the outgoing GOOSE. Thecommunications IED subscribes to this GOOSE message and will send the signal to theremote end.

It is used to combine and condition various trip signals into a signal trip condition. It can alsobe used to annunciate trips for other external signals. Can also separate the trip signal fromthe trip operation.

C.3 MDIF

This is a Measuring Logical Node for IEDs with differential protection functions.

In the case of a three terminal line differential protection, each IED at each terminal of the linewill measure the local phase and sequence components using MMXU and other measuringlogical nodes. Then this information is sent to the IEDs at the other ends of the line. Based onthe local measurement and the received measurements, each IED will calculate the differentialcurrent (the sum of the three vectors for each phase current) and the restrained (bias) current(the sum of the three scalars divided by some constant). These are available asmeasurements from each IED through the MDIF.
