IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations.It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. [1]
Modbus TCP nomenclature is the same as for the Modbus over Serial line protocol, as any device which send out a Modbus command, is the 'client' and the response comes from a 'server'. [29] The ADU for Modbus TCP is officially called Modbus TCP/IP ADU by the Modbus organization [30] and is also called Modbus TCP frame by other parties. [3]
It is primarily used for communications between a master station and RTUs or IEDs. ICCP, the Inter-Control Center Communications Protocol (a part of IEC 60870-6), is used for inter-master station communications. Competing standards include the older Modbus protocol and the newer IEC 61850 protocol. DNP overview diagram
Modbus PEMEX; Modbus Plus; Modbus RTU or ASCII or TCP; MPI – Multi Point Interface; OSGP – The Open Smart Grid Protocol, a widely use protocol for smart grid devices built on ISO/IEC 14908.1; OpenADR – Open Automated Demand Response; protocol to manage electricity consuming/controlling devices
An SCL file contains the following parts: Header: This part is used to identify version and other basic details of an SCL configuration file. Substation: This is the part dealing with the different entities of a substation including various devices, interconnections and other functionalities.
IEC TC 57 WG19 is involved in the harmonization CIM & SCL. This involves: Mapping of logical nodes of IEC 61850 (SCL) to equipment defined in CIM. Use Web Ontology Language to define the mapping patterns for the areas to which the automatic mapping cannot be performed. The complete approach should not modify the existing models to a large extent.

IEC Technical Committee 57 is one of the technical committees of the International Electrotechnical Commission (IEC). TC 57 is responsible for development of standards for information exchange for power systems and other related systems including Energy Management Systems, SCADA , distribution automation & teleprotection.
