    What is SCADA?
    • A complex computer based system that uses modern applications to analyse the
    electric power grid system to acquire data, monitor and control facilities and
    processes.
    • ‘’SCADA is a system operating with coded signals over communication
    channels so as provide control of remote equipment (using typically one
    communication channel per remote station)’’.
    Future Trends In SCADA
    First generation: ‘’Monolithic’’

    • In the first generation, computing was done by mainframe computers.


    • SCADA system were independent system with no connectivity to other systems.
    Wide area networks were later designed but RTU vendors to communicate with
    RTU.
    • The first generation SCADA system was redundant since a back-up mainframe
    system was connected at the bus level and was used in the event of failure of
    primary mainframe system.
    Future Trends In SCADA

    Second generation: ‘’Distributed’’

    • The processing was distributed across multiple stations which were connected
    through LAN and they shared information in real time.
    • Each station is responsible for a particular task thus making the size and cost of
    each station less than one used in first generation.
    Future Trends In SCADA

    Third generation: ‘’Networked’’

    • Due to usage standard protocols and the fact that many networked SCADA
    systems are accessible from the Internet, the systems are potentially vulnerable
    to remote attack
    Power System Automation

    • Power system automation is the act of automatically controlling the power


    system via instrumentation and control devices. Substation automation refers to
    using data from Intelligent electronic devices (IED), control and automation
    capabilities within the substation, and control commands from remote users to
    control power system devices.
    Automation Tasks:
    • Data acquisition
    • Power system supervision
    • Power system control
    • Power system automation
    Devices used in Power Automation
    • Intelligent Electronic Device
    • Instrument Transformers
    • Transducer
    • Remote Teminal Unit
    • Communication Port Switch
    • Meter
    • Digital fault recorder
    • Load Tap Changer
    • Re Closer Controller
    • Time Synchronization Source & Protocol Gateway
    • Protective Relay
    • Communication Processor
    Advantages

    • Efficient with less manpower


    • Flexible, simple and reliable
    • Self-checking and readability
    • Portable and cost efficient
    Disadvantages

    • Initial capital investment


    • Lack of trained personals
    • Troubled alarms
    Applications

    • Electric power system, operation and control


    • Manufacturing Industries or plants
    • Telecom and IT based system
    • Traffic controls
    • Lift and Elevator controls
    • Railway Traction
    • Water and Sewage treatment plants and supply management
    Conclusion

    • The government of India has decide to integrate all the state power utilities.
    Unified load dispatch center has to be build. So automation has lot more
    advantages it increases efficiency and increase standardization.
