PD IEC TS 61850-1-2:2020

What is PD IEC TS 61850‑1‑2 about?  

PD IEC TS 61850 is a series of communication networks and systems for power utility automation. A communication network is a collection of methods that users employ to pass on valuable information. PD IEC TS 61850‑1‑2 is a technical specification, is intended for any users but primarily for standardization bodies that are considering using IEC 61850 as a base standard within the scope of their work and are willing to extend it as allowed by the IEC 61850 standards. PD IEC TS 61850‑1‑2 identifies the required steps and high-level requirements in achieving such extensions of IEC 61850 and provides guidelines for the individual steps. 

PD IEC TS 61850‑1‑2 addresses the following cases: 

• The management of product-level standards for products that have an interface based on IEC 61850 
• The management of domain-level standards based on IEC 61850 
• The management of transitional standards based on IEC 61850 
• The management of private namespaces based on IEC 61850 
• The development of standards offering the mapping of the IEC 61850 data model at the CDC level 
• The development and management of IEC 61850 profiles for domains (underlying the role of IEC TR 62361-103 and IEC TR 61850-7-6) 

On the process side, PD IEC TS 61850‑1‑2 covers: 

• The initial analysis of how the existing IEC 61850 object models and/or communication services may be applied and what allowed extensions may be required for utilizing them in new or specific domains (including private ones). The results of that step are expected to be documented 
• The extension of the IEC 61850 object models for new domains. The typically associated work is to identify existing logical nodes which can be reused "as is", to determine if existing logical nodes can be extended, or to define new logical nodes 
• The purpose and process to use transitional namespaces, which are expected to be merged eventually into an existing standard namespace 
• The management of standard namespaces 
• The development of private namespaces 

Who is PD IEC TS 61850‑1‑2 for? 

PD IEC TS 61850‑1‑2 on communication networks and systems is useful for: 

• Administration departments 
• Software engineers 
• IT sector 
• Telecommunication sector 

Why should you use PD IEC TS 61850‑1‑2?  

The communication network is the sum of all the means and methods that an organization employs to communicate. On the technical side, PD IEC TS 61850‑1‑2 highlights the main basic requirements (mostly referring to the appropriate parts of the series that host the requirements or recommendations), lists all possible flexibilities offered by the standards and defines which flexibilities are allowed/possible per type of extension cases. 

PD IEC TS 61850‑1‑2 discusses namespaces that are largely used and widespread in the IT world to organize the names or identifiers of data types, data objects, functions, etc. into logical sets to prevent name collisions that can occur when these are being defined in parallel. In the specific case of IEC 61850, namespaces are a defined but structured collection of logical nodes (LN), data objects and potentially common data classes (CDC) and attributes. Using PD IEC TS 61850‑1‑2 you can identify required steps and high-level requirements to achieve extensions of IEC 61850.
