ATLAN-SPEC computer aided design tool
Unified information model
To ensure interoperability, it defines a unified information model for the description of IEDs, with specific data structures, and hierarchy levels:
Common Communications Protocol
Defines three common communications protocols and functionality, which enable the full range of message transmission needs required in a substation:
Setting requirements and adopting appropriate ‘technology’ standards
The 61850 standard sets the system performance requirements (low latency and high availability and accuracy) and uses other ‘technology’ standards for compliance:
Settings file formats SCL (Substation Configuration Description Language)
Establishes a configuration file format for equipment information and functions, and communication parameters, based on XML and a set of formats and tools to facilitate automation and configuration within the engineering process.
In the basic engineering stage, an SSD (System Specification Description) specification file is prepared with the description of the topology of the electrical system, the assignment of the Logical Nodes, the PICOMs (Piece of Information for COMmunication), and the functions required in it, without specifying specific equipment models.
Subsequently, when the manufacturers provide the ICD (IED Capabilities Description) files with the templates of the information models and capabilities of the real equipment, the SCD (Substation Configuration Description) file can be generated.
The SCD file contains the complete system configuration with the information models of real equipment. To complete the detailed engineering, external/internal wiring diagrams, component/material lists, and layout/wiring drawings are prepared.
ATLAN-SPEC is the tool developed by a strategic partner of Im3 for the computer-aided design of protection, automation and control (PAC) architectures with 61850 standard.
