Communication networks and systems for power utility automation - Part 5: Communication requirements for functions and device models (IEC 61850-5:2013); English version EN 61850-5:2013
Kommunikationsnetze und -systeme für die Automatisierung in der elektrischen Energieversorgung - Teil 5: Kommunikationsanforderungen für Funktionen und Gerätemodelle (IEC 61850-5:2013); Englische Fassung EN 61850-5:2013
Overview
This standard applies to power utility automation systems with the core part of substation automation systems (SAS). It standardizes the communication between intelligent electronic devices (IEDs) and defines the related system requirements to be supported. The specifications of this part refer to the communication requirements of the functions in power automation systems and related device models. All known functions and their communication requirements are identified. The description of the functions is not used to standardize the functions, but to identify communication requirements between Intelligent Electronic Devices (IED) within plants, between such stations (such as line protection) and between plants and substation and higher-level remote operating places (for example network control centers) and maintenance places. Also interfaces to remote technical services (such as maintenance centers) are considered. The general scope is the communication requirements for power utility automation systems. The basic goal is the interoperability for all interactions providing a seamless communication system for the overall power system management. Standardizing functions and their implementation are completely outside the scope of this standard. Therefore, it cannot be assumed a single philosophy of allocating functions to devices. To support the resulting requests for free allocation of functions, a proper breakdown of functions into parts relevant for communication is defined. The exchanged data and their required performance are defined. The same or similar intelligent electronic devices (IED) from substations like protective and control devices are found in other installations like power plants also. Using this standard for such devices in these plants facilitates the system integration for example between the power plant control and the related substation automation system. For some of such other application domains like wind power plants or hydro power plants and distributed energy resources the IEC 61850, first edition, has been already defined and published. The responsible body is DKE/K 952 "Netzleittechnik" ("Network control technology") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
