PD IEC/TS 61850-80-1:2016

What is PD IEC/TS 61850-80-1- Communication networks and systems for power utility automation about? 

PD IEC/TS 61850-80-1 is a safety standard on communication networks and systems for power utility automation. 

PD IEC/TS 61850-80-1, which is a technical specification, gives a guideline on how to exchange information from a CDC-based data model (for example IEC 61850) using IEC 60870-5-101 or IEC 60870-5-104 between substation(s) and control center(s). Most guidelines for functions needed in a substation gateway device are given. The goal of PD IEC/TS 61850-80-1 is to describe the standardized mapping of device-oriented data models (for example IEC 61850) with already defined attributes of CDCs and services (for example IEC 61850-7) onto the already defined ASDUs and services of IEC 60870-5-104 or IEC 60870-5-101. 

The scope of PD IEC/TS 61850-80-1 is to achieve real-time exchange of process information required for operational purposes between a substation using a CDC-based data model (for example IEC 61850) and (a) control center(s) using a communication link over a wide area network (WAN) compliant to the definitions of IEC 60870-5-101 or IEC 60870-5-104. The amount of real-time information provided by the substation-gateway device can vary dependent on the operational needs. Actors could be regional and nationwide control centers that receive real-time information to monitor and control geographically widespread processes. The described mapping can be used for several fields of application of power utilities, such as substations, hydro and wind power plants, and decentralized energy resources DER. PD IEC/TS 61850-80-1 focuses on defining the rules and functions of a gateway device as a part of the substation. 

Note 1: It is not the goal of this technical specification to add any extensions to published standards (for example IEC 61850 or IEC 60870-5-104 or IEC 60870-5-101). 

Note 2: The extended substation configuration description (SCD+) is recommended to be used to configure any gateway in a vendor-independent format. 

Who is PD IEC/TS 61850-80-1- Communication networks and systems for power utility automation for?  

PD IEC/TS 61850-80-1 on the guideline to exchanging information from a CDC-based data model is relevant to: 

• System developers 
• CDC data engineers 
• Testing authorities  
• Manufacturers of network components and end devices 
• Electrical engineers 
• Electricians 

Why should you use PD IEC/TS 61850-80-1- Communication networks and systems for power utility automation? 

PD IEC/TS 61850-80-1 describes the conceptual architecture of a gateway device within a substation. The gateway device is decoupling the IEC 61850 station bus from the IEC 60870-5-101 or IEC 60870-5-104 WAN via a process image (PI). 

The PI is organized according to the data model of IEC 61850 (LDs, LNs, CDCs). 

PD IEC/TS 61850-80-1 is used to: 

• Make process data coming from remote devices available for IEDs inside the substation. 

The IEC 60870-5-101 or IEC 60870-5-104 controlled and controlling functionality makes use of the attributes of CDCs in a defined way to build up ASDUs to communicate with the control centers or “devices on the WAN network" using WAN communication based on IEC 60870-5-101 or IEC 60870-5-104 (including redundant connections). 

Overall, PD IEC/TS 61850-80-1 is beneficial as it provides guidance on the IEC 60870-5-101 or IEC 60870-5-104 controlling functionality inside the gateway device which is used to connect “devices on the WAN networkˮ with IEC 60870-5-101 or IEC 60870-5-104 controlled functionality to the substation. 

What’s changed since the last update? 

PD IEC/TS 61850-80-1:2016 supersedes DD CLC/TS 61850-80-1:2010 which is withdrawn. 

PD IEC/TS 61850-80-1:2016 replaces the first edition published in 2008.  

PD IEC/TS 61850-80-1:2016 constitutes a technical revision. 

PD IEC/TS 61850-80-1:2016 includes the following significant technical changes with respect to the previous edition: 

• IEC TS 61850-80-1:2008 is based on the definitions of IEC 61850 Edition 1. After the publication of IEC TS 61850-80-1:2008 the standard series IEC 61850 was updated to Edition 2 (almost all parts) 
• IEC 61850-7-3:2010 introduces new Common Data Classes (CDCs) which are currently not mapped to IEC 60870-5-101 or IEC 60870-5-104 in IEC 61850-80-1:2008. Those new CDCs are ENS, HST, VSS, ENC, BAC, ENG, ORG, TSG, CUG, VSG, CSG. IEC 61400-25-4, which is currently being updated, refers to IEC TS 61850-80-1:2008 and therefore needs to be updated according to the definitions of this second edition of IEC 61850. The following CDCs are missing in the IEC 61850-80-1:2008 and have therefore been added to this new edition for IEC 61400-25-4 Edition 2: ENS, ENC, ENG, ORG
