    This document discusses the evolution of process bus based automation in substations, including the development of the IEC 61850 standard. It notes that early substation control and communication faced challenges with cabling and proprietary protocols. IEC 61850 aimed to address these issues through standardized data models and information exchange to allow interoperability between devices from different manufacturers. It established logical nodes and other object-oriented approaches to represent power system elements. Key aspects of the standard include GOOSE messaging for fast protection, MMS for client-server communication, and sampled values for synchrophasor data exchange. The document describes pilot installations of IEC 61850 process bus systems at various substations in India.

    EVOLUTION OF

    PROCESS BUS BASED AUTOMATION


    IN SUBSTATIONS
    CONVENTIONAL CONTROL & PROTECTION SYSTEM
    CONTROL ROOM WITH FACIA PANELS PLACED IN CONTROL ROOM

    CABLE VAULT
    CONVENTIONAL COMMUNICATION
    IN SUBSTATIONS
    DEVICE TO DEVICE- Through Cables

    OUTSIDE THE SUBSTATION- RTUs

    ADVENT OF PROPRIERATY COMMUNICATION


    PROTOCOLS

    • Profibus - initially promoted by German department of


    education and research & then by Siemens)
    • Modbus - originally published
    by Modicon (now Schneider Electric)
    WHAT LEAD TO EVOLUTION OF
    IEC 61850
    • Burden Requirements
    • Commissioning delays owing to enormous
    cabling, trenches etc.
    • Optimization
    • Constraint in deploying complex schemes through
    cables
    • Development in network, communications & IT
    • Arbitrariness in existing protocols for information
    exchange

    IEC 61850 STANDARD
    Goals…

    IEDs from different manufacturers are able to


    exchange information and can
    perform combined functionality with each other.
    The standard shall support different
    philosophies. It should allow manufacturers
    and utilities a certain degree of freedom to
    support specific requirements of
    different systems.
    The standard must be able to follow the
    progress in the communication
    technology as well as system requirements.
    OBJECT ORIENTATION
    All Object Names are Standardized and Defined in a
    Power System Context:-The names of the data in the IEC 61850
    device are not dictated by the device vendor or configured by the
    user. All names are defined in the standard and provided in a
    power system context that enables the engineer to immediately
    identify the meaning of data without having to define mappings
    that relate index numbers and register numbers to power system
    data like voltage and current.

    ADVANTAGE OVER CONVENTIONAL RTU TYPE


    COMMUNICATION
    Interoperability

    Interoperability is achieved
    through standardized data
    models and information
    exchange. It should not be
    confused with Interchangeability.
    Interchangeability would be the
    possibility to simply replace one
    IED by the other. That's however
    explicitly
    beyond the scope of IEC 61850.
