Integration of Iot technologies into the Smart GridBog'liq sensors-22-02475-v24. IEC61850 Web Platform
The IEC 61850 Web Platform proposed here is based on the adoption of a REST ar-
chitectural style and is shown in Figure 4. As can be seen, it offers access to one or more
IEC 61850 Servers to a Web User.
Figure 3.
Example of the IEC 61850 data model used throughout the paper.
The IEC 61850 standard provides the representation of an IEC 61850 system configu-
ration of electrical devices, including representation of data and communication services,
using an XML-based file format called Substation Configuration Language (SCL). The SCL
file is divided into sections, each of which provides different information. The header
section includes general topics and details about SCL and the file version. The IED section
describes devices capacities, functions, and data it manages, and provides a description of
the Logical Devices, Logical Nodes, and Data Objects present in the system. The DataType-
Templates section describes the data model by defining the Logical Node Types, the Data
Object Types, the Data Attribute Types, and the Enumeration Types used. The communi-
cation section contains communication details. The substation section describes electrical
topology for substation or any other electrical process.
The IED Capability Description (ICD) file is a specific type of Substation Configuration
Language (SCL) file, containing a generic description of the whole capability range of a
given device, including the functions and objects it can support. The ICD file is usually
supplied by the developer/manufacturer.
IEC 61850 standardizes the set of abstract communication services that allows the com-
patible exchange of information among components of a Power Utility Automation System.
IEC 61850 offers several types of communication models, including the Client/Server type
communication services model [

]. An IEC 61850 Server may be used to maintain, and
make its content available to, IEC 61850 Clients, in terms of data structured according to
the IEC 61850 data model shown by Figures
1
and
2
. An ICD file is always available in the
IEC 61850 Server to describe its full content.
