SCADA — Supervisory Control and Data Acquisition

What is SCADA?
SCADA — Supervisory Control and Data Acquisition
Supervisory control and data acquisition (SCADA) systems collect, monitor and process real-time data to:
- Automate and control industrial processes remotely or locally
- Provide a human-machine interface (HMI) to directly interact with devices such as relays, sensors, generators, pumps, valves and others
- Record events and automate reporting
- The SCADA software processes, allocates and displays the data to support operators in their decisions and reports information such as failures, alarms or performance data. to several actors.
- The commands send through the SCADA by the operator are commonly executed on-site from a single access point via remote control units (most commonly RTUs/gateways, sometimes PLCs).
- RTUs are computers that can communicate with a range of devices in the facility, including meters, HMIs, IEDs, sensors and many others. They route the data they collect from these object to the servers running the SCADA software.

Grid & Substation Automation
- RTU — Remote Terminal Unit
- SCADA — Supervisory Control and Data Acquisition
- IED — Intelligent Electronic Device
- SER — SEQUENCE OF EVENTS RECORDING
RTU most commonly stands for Remote Terminal Unit, but is sometimes also used as an abbreviation for Remote Telemetry Unit or Remote Telecontrol Unit.
RTUs are devices that rely on microprocessors and communication interfaces to automatically monitor and control field devices and establish a bridge to the plant control or SCADA (supervisory control and data acquisition) systems.
Supervisory control and data acquisition (SCADA) systems collect, monitor and process real-time data to:
- Automate and control industrial processes remotely or locally
- Provide a human-machine interface (HMI) to directly interact with devices such as relays, sensors, generators, pumps, valves and others
- Record events and automate reporting
An Intelligent Electronic Device (IED) is a term used in the electric power industry to describe microprocessor-based controllers of power system equipment, such as circuit breakers, transformers and capacitor banks.
Sequence of events recording (SER) is performed by microprocessor based systems, which monitor collected data inputs and record the time and sequences of the changes.
Sequence of events recorders rely on external time sources such as GPS or radio clocks to record the exact time of state of each change.
