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).
