A 615 series IED can send any type of status or measurand data in the GOOSE

messages from its IEC 61850 data model. The status data response time, that is, the

time it takes for the application to handle a received GOOSE message and to send

the concerned data back to the network, is with the 615 series IEDs below 3 ms.

The response time fulfils the tightest Type 1A, Class P2/3 requirements of the

standard.

When a 615 series IED is configured to send measurements, the analog, integer or

counter type of data should be placed on its own dataset. The triggering of analog

type of data sending is controlled by deadband handling, zero-point clamping and

limit supervision.

The horizontal communication configuration consists of the IEDs’ GOOSE control

block, data set and GOOSE input configuration. The result of the configuration

work is a system configuration file which can be downloaded to the IEDs. The

used files in the workflow are IEC 61850 standard format SCL files.

GOOSE is used in substation automation for fast horizontal communication

between the IEDs. GOOSE can be used for direct data exchange, for example, of

interlocking and blocking information between IEDs. According to the IEC

61850-8-1 standard, GOOSE uses a publisher/subscriber profile in which

information is shared from one IED to one or several IEDs by using Ethernet

multicast messages. A message is an image of a sent IEC 61850 data set that is

defined in the configuration.

IET600 is used to configure the vertical and horizontal communication properties

of the 615 series IEDs.

Configuring horizontal communication

See detailed descriptions of the steps in corresponding chapters.

1. Add devices to a PCM600 project.

2. Export the SCD file.

3. Import the SCD file to IET600.

4. Engineer the GOOSE connections between the devices

4.1. Define the published GOOSE data and control blocks.

4.2. Define the subscribing IEDs for the GOOSE data.

5. Export the SCD file back to PCM600.

6. In PCM600. engineer the IED applications with GOOSE inputs.

PCM600 uses IEC 61850 over Ethernet to communicate with bay IEDs. This

communication allows PCM600 to configure and monitor the IEDs. In addition to

IEC 61850 the IEDs have optional communications protocols and hardware to

connect to station engineering tools. PCM600 provides the ability to export the

configuration of the IEDs or entire substation in a standard file format which

allows for station engineering.

A PC with PCM600 can be connected to any 615 series IED within a station by

using the Ethernet connection. The connection can also be used for service and

maintenance purposes. In addition, the connection is used to handle disturbance

records from the protection IEDs using the IEC 61850 file transfer.

The modern-day IEDs are designed using the concept of the IEC 61850 standard.

This is primarily in regards to how functions within the IED are modelled and how

the IED is represented in the substation. See the IEC 61850 parameter list for the

list of logical nodes available in the IED and observe how they follow the structure

and rules as defined in part 7 of the standard.

The engineering of the used communication protocols is a separate task and an

addition to the engineering of protection and control functions.

PCM600 can be used for different purposes throughout the IED life cycle. A set of

special tools is available for different applications.

Protection and Control IED Manager PCM600 offers all the necessary functionality

to work throughout all stages of the IED life cycle.

• Engineering

• Commissioning

• Operation and disturbance handling

• Functional analysis

With the individual tool components, you can perform different tasks and functions

and control the whole substation. PCM600 can operate with many different

topologies, depending on the customer needs.

PCM600 is used to conduct complete engineering and configuration activities

needed for the bay level IEDs.Connectivity Packages are separate software packages that provide type

and version information to PCM600. Further Connectivity Packages assist the tool with

communications.

PCM600 uses IEC 61850 over Ethernet to communicate with bay IEDs. This

communication allows PCM600 to configure and monitor the IEDs. In addition to

IEC 61850 the IEDs have optional communications protocols and hardware to

connect to station engineering tools. PCM600 provides the ability to export the

configuration of the IEDs or entire substation in a standard file format which

allows for station engineering.

The IEC 61850 standard specifies an expandable data model and services for

substation automation (standard parts 7-x). The standard does not specify any

protection or control functions, but specifies how the functions expose their

information to a communication network.

The standard supports free allocation of functions to devices. With efficient

communication facilities, the functions can be located anywhere in the system, that

is, an interlocking function can reside in the IED or on the station level.

Additionally, the standard is open for different system implementations, that is,

different integration levels and allocation of functions to different devices is

supported.The standard also defines an XML description language for substation automation

systems. The language facilitates efficient integration of devices into systems in an

automated fashion. Additionally the standard supports a comprehensive and

consistent system definition and engineering, which makes not only the devices,

but also their tools and systems interoperable (standard part 6).

The international IEC 61850 standard defines a framework for substation

communications networks and systems. The standard consists of several parts

ranging from the requirements on substation automation systems to the details of a

communication protocol.

One major difference between the other communication protocols applied in

substation automation and IEC 61850 is that the latter is not only a communication

protocol, but a whole framework for specifying, engineering and operating

substation automation systems. The communication part covers the connection

between the IEDs and the substation clients, for example, SCADA and gateways.

The standard also defines an XML description language for substation automation

systems. The language facilitates efficient integration of devices into systems in an

automated fashion. Additionally the standard supports a comprehensive and

consistent system definition and engineering, which makes not only the devices,

but also their tools and systems interoperable (standard part 6).

The standard uses Ethernet and TCP/IP for communication. Since Ethernet and TCP/

IP are widely accepted and used, the application of these technologies provide a

broad range of features from mainstream communication (standard parts 8-1. 9-2).

However, IEC 61850 is also open for possible new communication concepts in the

future.
