General Information

This document describes the Basler Electric IEC 61850 Protocol implementation in the BE1-11 series of protection systems. A BE1-11 is classified as an intelligent electronic device (IED) that is capable of sending and receiving IEC 61850 messages simultaneously.

The IEC 61850 protocol is an option available when ordering a BE1-11. An Ethernet connection is required for operation of IEC 61850.

IEC 61850 is a communications infrastructure that allows seamless integration of IEDs into higher level devices. IEDs from different vendors can be integrated together in this vendor independent infrastructure. A typical station bus is illustrated in Figure 1.

Protection, control, and metering for the substation are defined in an SCL (Substation Configuration Language) file. The BE1-11 comes with an SCL compatible ICD (IED Capability Description) file that is uploaded to the BE1-11 as a CID (configured ICD) file. The substation design developer uses the CID file to create the portion of the SCD (Substation Configuration Description) file for the overall substation design.

Figure 3. Reference Model for Information Flow in the Configuration Process

The IEC 61850 standard defines two tools and four file types for Engineering as illustrated in Figure 3. The tools and file types are defined below.

System Configurator

The System Configurator performs the following functions:

•Imports and exports configuration files

•Imports configuration files from several IEDs for system level engineering

•Generates a substation related configuration file

•Reads an SSD file as a base for starting system engineering or for comparisons

The complete station configuration is exported in the SCD file for further use by the various IED configuration tools.

IED Configurator Tool (BEST61850™)

BEST61850 performs the following functions:

•Imports an SCD file and extracts the necessary information for each IED in the system

•Maps subscribed GOOSE messages between devices

•Configures published GOOSE messages

•Configures DataSets

•Configures Report Control Blocks (RCB)

•Creates a CID file and uploads it to the IED or exports it to a file

•Performs any additional engineering operations

ICD File (IED Capability Description File)

The capabilities of an IED are described in this file. The file contains logical node type definitions and may contain an optional substation section.

SSD File (System Specification Description File)

This file describes the single line diagram of the substation and the required logical nodes. It contains a substation description section and the data templates and logical node definitions.

SCD File (Substation Configuration Description File)

This file contains the data exchanged from the system configuration tool to the IED configuration tool. It contains all IEDs, a communication configuration section, and a substation description.

CID File (Configured IED Description File)

This file contains the data exchanged from the IED configuration tool to the IED.

SCL Object Model

The SCL (Substation Configuration Language) object model consists of the following parts:

•The primary (power) system structure

•The communications system

•The application level communication

•Each IED

•Instantiable logical node (LN) type definitions

•The relations between instantiated logical nodes and their hosting IEDs on one side and the switchyard (function) parts on the other side

Figure 4 shows an instance of the SCL object model: a simple example of an SA (Substation Architecture) system used for a switchyard. The switchyard has a 110 kV voltage level E1. It is a double bus bar system with two line bays =E1Q1 and =E1Q3, and a bus coupler =E1Q2. The IEDs are already assigned to switchyard functionality (for example the bay controller –E1Q1SB1 as a product is assigned to bay =E1Q1, and its Logic Node CSWI1 controls the circuit breaker =E1Q1QA1 via the Logic Node XCBR1 on the IED –E1Q1QA1B1). Figure 4 uses a – (minus) sign to indicate the product-related designations. The functional name is not repeated. The station level communication sub network is named W1. There are three additional sub networks at process level (W2, W3, and W4).

Figure 4. Configuration Example (from IEC 61850-6)

The IEC 61850 standard is based on the hierarchical addressing and information model in a station. It follows, in this way, the structure of the substation equipment independent of IED structure and organization. This information and addressing model is also visible in the IEC 61850 telegrams because the address is presented in MMS (Manufacturing Message Specification) as an ASCII string, so the address can be seen directly in a readable form.

The IEC 61850 standard defines the information and its exchange in a way that it is independent of a concrete implementation (i.e., it uses abstract models). The standard also uses the concept of virtualization. Virtualization provides a view of those aspects of a real device that are of interest for the information exchange with other devices. Only those details that are required to provide interoperability of devices are defined in the IEC 61850 standard.

The approach of the standard is to decompose the application functions into the smallest entities, which are used to exchange information. These entities are called logical nodes (for example, a virtual representation of a circuit breaker class, with the standardized class name XCBR). Several logical nodes build a logical device (for example, a representation of a Bay unit). A logical device is always implemented in one IED; therefore logical devices are not distributed.

Real devices on the right-hand side of Figure 5 are modeled as a virtual model in the middle of the figure. The logical nodes defined in the logical device (for example, Bay) correspond to well-known functions in the real devices. In this example, the logical node XCBR represents a specific circuit breaker of the bay to the right.

Figure 5. Modeling Approach Example

Substation Configuration Description Language (SCL)

The SCL language is based on XML (Extensible Markup Language). Detailed knowledge about an XML file is not required, but the information within the file may be of interest. An SCL XML file is divided into the following five sections as specified in IEC 61850-6:

•Header

•Substation description

•Communication system description

•IED description

•Data Type Templates

The Header identifies an SCL configuration file and version, and specifies options for the mapping of names to signals. The Substation section describes the functional structure of a substation, and defines the primary devices and their electrical connections.

Default ICD files in BEST61850 software are used to define the Header and Substation description sections. Logical nodes of the IED are logically linked to the substation section. BEST61850 software is used for signal engineering and routing of the signals. BESTCOMSPlus must be used to define the substation and communication sections prior to using BEST61850. BEST61850 is used to configure the DataSets and Control Blocks that are located in the IED section. The DataSets and Control Blocks (Report, GOOSE, and Setting) are logically defined as part of the logical nodes per IEC 61850-7-2. GOOSE engineering requires that BEST61850 has the correct configured Communication description section. The Data Type Templates section gives the correct content description of each logical node type to the clients. Logical node type definitions may vary between each IED and vendor.

Figure 6 shows the principle structure of the SCL XML file. The arrows show the link between the different sections given when an IED is integrated in the substation structure and/or in the communication structure. All available logical nodes of an IED are linked to the substation section.

A reference to the GoCB (GOOSE Control Block) is included in the communication section when the GoCB is configured. The graphical presentation of the XML file is a standard view of XML editors. It gives a better picture about the structure of the XML contents.

Figure 7. Elements of the Signal Identification as Defined in IEC 61850-7-2

The signal designation consists of the following four parts:

1.A user defined part identifying the Logical Device LD in the process (LDName).

2.A function related part to distinguish several LNs of the same class within the same LD/IED (LNPrefix).

3.The standardized LN class name and the LN instance number, which distinguishes several LNs of the same class and prefix within the same LD/IED.

4.A signal identification inside a LN consisting of data and attribute name as defined in IEC 61850– 7–3 and IEC 61850–7–4.

IED Related Naming

The LDName part is built out of the objects IED and LDevice. The LNName is the LN Prefix, the LN class and the LN instance #.

The LN prefix is used to identify several versions of a LN class. The link between the IED and the primary process (Substation, Voltage level, Bay) is given in the substation section of the station SCD file but not in the signal identification in the telegram. The IED name may be extended with a short form of the three missing levels. See Figure 8.

In the IED (product) structure, this LN is identified as -E1Q1SB1LD2CSWI2.

Communication Network Section

The organization of the physical IEDs to the communication network is independent of the substation structure. The IEC 61850 standard defines the communication network with no relation to an existing media and protocol. The first mapping to an existing media and protocol is done in IEC 61850–8–1 with:

•Ethernet as medium

•MMS (Manufacturing Message Specification) protocol as defined in ISO 9506–1 and ISO 9506–2

The IEC 61850 standard describes in part 7–2 the Abstract Communication Service Interface (ACSI) in a media and protocol independent form. Part 8–1 specifies the mapping of this ACSI to the existing MMS.

The communication section in the SCL file describes the minimum of what is needed to identify how information is routed between the IEDs in a project. This is:

•the used sub networks

•the IEDs connected to the different sub networks

BE1-11

IEC 61850 Engineering

•the access points per IED to the sub networks

•the address

•the IP address of the LAN network is an exception also part of the address elements

•extended during signal engineering and routing, the link to the GoCB message in transmission direction

IED Section

The IED section describes the complete IED as it is needed for IEC 61850 communication. The Data Type Template part of an IED may be seen as part of the IED, even when separated in its own section. The IED’s ICD file includes the description of the LNs, their Data Type Templates, and the used/supported services. The structure of the IED section follows the definitions made in the IEC 61850 standard.

Figure 11 illustrates organization of LDs, LNs, DOs, and DAs in an IED.

Figure 11. Organization of LDs, LNs, DOs, and DAs in an IED

An IED server represents the communication interface to the sub network (Ethernet).

•One or more Logical device(s) are connected to a server

•A set of Logical Nodes belong to a Logical Device

•The Logic Node LLN0 is a special Logic Node per Logic Device and contains the DataSets, GOOSE Control Blocks (GoCB), Report Control Blocks (RCB), and Setting Group Control Block (SGCB)

•The Logic Node LPHD is a special Logic Node per Logic Device and contains Data Objects (DO) which describe the status of the physical device (the IED)

•Each Logical Node represents a function and contains a number of Data Objects (DO)

•Each DO is represented by a number of Data Attributes (DA)

The data objects are representing information signals which may be routed to station level IEDs.

The signal engineering task is to select the requested signals (DOs) and link them to the client IEDs as receiver. The control services are not directly engineered. They are included in the data objects which handle both directions the command (control) and the response (monitoring). When routing the DO in monitoring direction the control is known by the clients. The organization of the IED from LD down to DAs can be viewed in the BEST61850 tool. This organization concept must be taken into consideration when DataSets are configured.

The number of data objects and data attributes per Logical Node is defined by the used LN type in this IED. The contents are taken from the Data Type Templates which belong to an IED type.

Signal Engineering

Signal engineering consists of DataSets, Report Control Blocks (RCB), and Goose Control Blocks (GoCB).

DataSets

IEC 61850 has defined DataSets for signal transmission in Report Control Blocks. DataSets are also used for GOOSE messages. Figure 12 shows a DataSet where all position information of the apparatuses of a bay are put into one DataSet.

Figure 12. DataSet Example

General rules for DataSet configuration:

•All data objects or their data attributes can be selected for a DataSet.

•Only those data attributes of a data object are selected which have the same functional constraint (FC).

•Data objects with different FC can be selected for a DataSet. For example DOs with FC=ST and DOs with FC=MX can be members in one DataSet.

•A single data attribute can be selected when it is specified with a trigger option. For example the data attribute stVal of the data object Pos can be selected as a member of a DataSet, because it is specified with the trigger option data change detected (dchg).

The description of the DataSets and the list of data object members or FCDAs (Functionally Constrained Data Attributes) is included in the SCL file in the IED section in the Logical Device subsection. FCDAs are

IEC 61850 Engineering

also referred to as Data Tags. As specified in IEC 61850–7–2 clause 9, the DataSets are part of a Logical Node. They are included in the LLN0.

Report Control Blocks (RCB)

The contents of an RCB are listed in IEC 61850– 7–2 in clause 14, table 23. The RCB contains a list of attributes which handle and secure the communication between the client and the server.

•Buffer Time - This parameter describes how long the report should wait for other expected events before it sends the report to the client. When known, additional events are generated as a follow up. It is useful to wait for approximately 500 ms for additional events stored in the report. This feature reduces the number of telegrams transmitted in case of a burst of changes. But it increases the overall transaction time for events from IED input to presentation on HMI which is normally one second.

•Trigger Options - Data attributes have three trigger options (dchg, qchg, dupd). Within the RCB, two others can be defined integrity and general interrogation. The attribute Trigger Option is a multiple choice and allows masking of the supported trigger options in this RCB.

•Integrity Period - When period is selected in the trigger option attribute, it is needed to define an integrity period to force the transmission of all data listed in the DataSet. This is done by the attribute Integrity Period. This feature can be used as a background cycle to ensure that the process image in all partners is the same.

•General Interrogation - A general interrogation is only done on request from a client. Not all DataSets contain information which is needed for a general update of the client. For example, data with T(ransient) = TRUE are not part of a GI. When the RCB attribute general interrogation is set to TRUE a GI request from the client will be handled. The report handler will transmit all data defined in the DataSet with their actual values. The IEC 61850 standard defines that all buffered events are transmitted first before the GI is started. A running GI is stopped and a new GI is started, when a new GI request is received while a GI is running.

Trigger Options

IEC 61850 has defined five different TrgOp. Three of them belong to data attributes and they are marked per data attribute in the column TrgOp of the CDC tables in part 7–3. The other two belong to the configuration of control blocks. The five trigger options are:

•dchg = data-change - The classical trigger. Whenever a process value has changed its value either binary or a measurement a transmission is done.

•qchg = quality change - Looking to the possibilities of the quality data attribute type (q) any changes in the quality description are transmitted.

•dupd = data value update - This trigger option gives the possibility to define that a transmission should be done on a condition which can be controlled by the application.

•Period - This trigger forces the transmission of all process values defined in the DataSet when a timer value (the integrity period) expires. For example, it can be used to do a process signal update in the background (e.g. every 15 minutes).

•General Interrogation - This trigger is forced by the clients (= station level IED; NCC gateway, station HMI, ...). Normally a GI is asked for when the client and the server start or restart a session. When the client is able to receive the actual values and when the Logical Device has scanned all process values at least once, an image of the actual process signal status can be transmitted to the client.

Goose Control Blocks (GoCB)

The Generic Object Oriented Substation Event (GOOSE) class model is used to distribute input and output data values between IEDs on bay level through the use of multicast services. GOOSE messages bypass the server which results in a fast transmission from publisher to one or several subscribers (receivers).

The GOOSE message concept is used for all application functions where two or more IEDs are involved.

To send GOOSE messages, a GoCB must be defined and a DataSet is needed which contains the data objects of single data attributes to be sent. A GOOSE message is forced to be transmitted when a trigger change is detected for a data attribute. All members of the DataSet will be copied in the send buffer with their actual value and the message is sent. All subscribers which know the address of this GOOSE message will receive the telegram. The GOOSE message includes a sequence number and a state number to verify that all messages are received.

In the SCL communication section in the GSE element, the GoCB is listed under the ConnectedAP.

The IEDs which should receive a GOOSE message are informed in the SCL private section that they will receive GOOSE messages. This is given when the external Reference, the name of the IED, and the member of the DataSet is included in the LLN0 logic node under the structure of the Logic Device (LD) of the receiving IED. The IEDs which receive the GOOSE are selected by BEST61850.

The IEC 61850 principle operation of GOOSE messages is illustrated in Figure 13.

BESTCOMSPlus®

BESTCOMSPlus is a Windows®-based, PC application that provides a user-friendly, graphical user interface (GUI) for use with Basler Electric communicating products. BESTCOMSPlus is used to program IEC 61850 logic. It is also used to program BE1-11 operational settings and other logic. For more information, refer to the BESTCOMSPlus Software chapter in the appropriate BE1-11 instruction manual below:

•9424200990 - Instruction Manual for BE1-11f

•9424200993 - Instruction Manual for BE1-11i

CTLGGIO OPER Output and INDGGIO OPER Input

The IEC 61850 GGIO IND outputs and OPER inputs in BESTCOMSPlus are used to map BE1-11 inputs and outputs to IEC 61850 data points. These data points can be read directly with an IEC 61850 browser such as IED Scout made by Omicron. The GGIO inputs and outputs can be used in an IEC 61850 DataSet which is tied to GOOSE Control Blocks (GoCB) for sending/receiving GOOSE messages.

A CTLGGIO 61850 logic output and INDGGIO logic input are shown in Figure 14.

CTLGGIO OPER Alarm

The CTLGGIO OPER ALARM is set if the device has subscribed to a GOOSE message, mapped it to the corresponding CTL GGIO, and the device has not received the subscribed GOOSE message within the TTL (Time To Live). The TTL for the next reception is included within a GOOSE message. If the TTL timer expire and the alarm is set, the CTLGGIO OPER logic input will switch over to the default that is configured within the BE1-11 settings. If the device starts receiving GOOSE messages again, the alarm will be reset and the CTLGGIO OPER logic input will be set to the value in the GOOSE message.

A CTLGGIO 61850 logic output and INDGGIO logic input are shown in Figure 14.

IEC61850PTRC Logic Block

The IEC61850PTRC logic block is available to set the corresponding status outputs in the IEC61850 PTRC node. The trip output for the BE1-11 should be connected to the Operate-General input of the block. If trip statuses of individual phases are known, use BESTlogic™Plus to connect them to the Phase A, Phase B, and Phase C logic inputs.

Functional Constraints

The IEC 61850 standard defines a number of functional constraints that indicate the data attribute is used for some particular purpose, such as reporting (BR/RP), configuration (CF), control (CO), description (DC), extended definition (EX), GOOSE control (GO), logging (LG), measured analog value (MX), setting groups (SG), setpoint (SP), and status (ST). The functional constraints of a DATA instance determines the rights of services to read and/or write the DATA.

DATA OBJECT

The DATA OBJECT or DATA class (abbreviated DO) like the LN class, is a key element of the IEC 61850 standard. Values of DATA instances represent meaningful information about substation devices, such as currents, voltages, power, phases, temperatures, status, timestamps, and so on. The DATA OBJECT may contain attributes which are themselves instances of the DATA class. Hence, it can be said that the DATA class is recursively defined.

DATA ATTRIBUTE

The DATA ATTRIBUTE class (abbreviated DA) contains the smallest piece of data that can be defined in IEC 61850. The DA class includes definition of instance name, reference, type, and presence. Presence indicates whether or not the data is mandatory or optional.
