SCADA systems are used to monitor and control geographically dispersed assets, like pipelines, power grids, and water distribution systems. SCADA systems connect to physical equipment like sensors and valves and gather data which is sent to centralized data acquisition systems for monitoring and processing. Key components of SCADA systems include remote terminal units for data collection, programmable logic controllers, telemetry systems for data transfer, and human-machine interfaces for display of information. SCADA systems provide advantages like reduced costs and increased efficiency for monitoring large remote assets.

- 3. Power system automation S Electrical power system S What is power system automation S Automation tasks S IEDs S Automation process S Advantages S Disadvantages S Applications S Conclusion
- 5. 1940 1950 1960 1965 1970 Electric utility systems Telemetry and control Development General Electric and Control Corporation Solid state devices were developed Advanced Telemetry
- 6. • Remote Terminal Unit(RTU) • Programmable logic Controller(PLC) • Telemetry system • Human machine interface • Data Acquisition Server • A supervisory (computer) system, gathering (acquiring) data on the process and sending commands (control) to the SCADA system. • Communication infrastructure connecting the supervisory system to the remote terminal units. • Various process and analytical instrumentation.
- 9. 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.
- 10. Any device incorporating one or more processors with the capability to receive or send data/control from or to an external source (e.g., electronic multifunction meters, digital relays, controllers)
- 11. Instrument transformers are used to sense power system current and voltage values. They are physically connected to power system apparatus and convert the actual power system signals, which include high voltage and current magnitudes, down to lower signal levels
- 12. Transducers convert the analog output of an instrument transformer from one magnitude to another or from one value type to another, such as from an ac current to dc voltage.
- 14. • Power supply • Digital or Status inputs • Analog inputs • Digital (control) outputs • Analog outputs • Software and logic control • Communications IED communications Master communications
- 15. A programmable logic controller, PLC or programmable controller is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines.
- 16. • Human Machine Interface commonly known as HMI are deployed for control and visualization interface between a human and a process, machine, application and appliance. Increasingly, HMIs are becoming an integral part of Factory Automation.
- 17. • Network
- 18. Communication and software S The SCADA consist of Hardware and Software components. S The hardware collects and feed data into a computer with SCADA software installed. S The data is then processed by the computer before presenting it in a timely manner.
- 19. A structured set of data is held in a computer for the future reference
- 20. A communications processor is a substation controller that incorporates the functions of many other I&C devices into one IED. SEL-2030 Communications Processor
- 21. A communications switch is a device that switches between several serial ports when it is told to do so. The remote user initiates communications with the port switch via a connection to the substation, typically a leased line or dial-up telephone connection. Once connected, the user can route their communications through the port switch to one of the connected substation IEDs. The port switch merely “passes through” the IED communications.
- 22. A meter is an IED that is used to create accurate measurements of power system current, voltage, and power values. Metering values such as demand and peak are saved within the meter to create historical information about the activity of the power system
- 23. A digital fault recorder (DFR), is an IED that records information about power system disturbances. It is capable of storing data in a digital format when triggered by conditions detected on the power system. Harmonics, frequency, and voltage are examples of data captured by DFRs.
- 24. Load tap changers are devices used to change the tap position on transformers. These devices work automatically or can be controlled via another local IED or from a remote operator or process.
- 25. Re closer controllers remotely control the operation of automated re closers and switches. These devices monitor and store power system conditions and determine when to perform control actions. They also accept commands from a remote operator or process.
- 26. A time synchronization source is an IED that creates a time-of- day value which is then broadcast to the IEDs in order to set all their clocks to the same time. IEDs communicate over serial connections by speaking a particular language or protocol. A protocol gateway converts communications from one protocol to another. This task is often performed by software on a personal computer.
- 28. A protective relay is an IED designed to sense power system disturbances and automatically perform control actions on the I&C system and the power system to protect personnel and equipment. SEL-351 Relay
- 32. First generation: "Monolithic“ Second generation: "Distributed“ Third generation: "Networked"
- 36. A smart grid is a modernized electrical grid that uses analogue or digital information and communications technology to gather and act on information, such as information about the behaviours of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity. Electronic power conditioning and control of the production and distribution of electricity are important aspects of the smart grid.
- 37. A smart meter is usually an electronic device that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing.
- 38. • In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load.
- 39. The government of India has decided to integrate all the state power utilities. Unified load dispatch Centre has to be build. So automation has lot more advantages as it increases efficiency and increase standardization. India is moving ahead toward automation are you??
