Introduction
GUID-C6EDEAE2-11F8-4F54-9091-CC0F9929D8A8 v1
This chapter describes the engineering process as outlined in IEC 61850-6 Edition 2. In general
IEC 61850-4 defines three roles for engineering tools, which allows combining more than one
role in a single tool.
•
System Configuration Tools (SCT) define the dataflow between a SAM600 system and
other equipment in an IEC61850 system. Common topics for several IED and logical
associations of functions embedded in the IED which control and supervise the primary
process are configured.
According to IEC 61850-6 Edition 2, SCT handle the following SCL sections:
•
Substation section including references to logical nodes on SAM600 systems
•
Communication section including project specific instance addresses
•
Datasets and control blocks, as allowed by a SAM600 system capabilities
•
Allocation of data flow and control block instances to clients, as allowed by a
SAM600 system capabilities
•
Creating SAM600 system input sections from system engineering without binding
to SAM600 system internal signals
•
Reorganizing the
DataTypeTemplate section to keep the type identifiers unique and
the template section short. The instance information is unchanged when the
templates are expanded in SAM600 system instances
•
IED Configuration Tools (ICT) handle a specific device configuration and downloading a
respective SAM600 system configuration to the target device. The configuration
generated from an ICT can be imported to a SCT for further engineering.
The following data model changes are allowed by ICT according to IEC 61850-6 Edition 2:
•
Addition of logical devices, logical nodes or DATA within logical nodes
•
Removal of logical devices, logical nodes or DATA, which are not referenced by
clients or bound to the primary system description (substation section)

SAM600 system engineering
GUID-C46D855A-9A0F-4BBB-91B5-5AE7C87C8788 v1
The system engineering of the substation automation system in IEC 61850 based substations
is done either using a
top-down or a bottom-up approach.
•
In the top-down engineering process, the system integrator selects the appropriate
library ICD files representing a SAM600 system type and builds the SCD according to the
substation design. In this phase, the substation configuration includes all SAM600
systems, single-line diagrams, sample value links between the devices. The SCD file is
imported to a SAM600 IED configuration tool where a SAM600 systems are parameterized
and configured according to the application or power system specifications.
•
In the bottom-up approach, the workflow starts from a SAM600 IED configuration tool
which creates the set of SAM600 systems and exports the initial IID files to the System
Configuration Tool. The IID file contains default values of single-line diagrams and
MSVCB’s for the communication between server SAM600 systems.
In simple cases, default values meet the customer specifications. In the System Configuration
Tool, the system engineer creates sample value links and customizes the details of single-line
