Substation Automation and SCADA system

Substation Automation:

  • IEDs (Intelligent Electronic Devices) – Relays, meters, and controllers for automation.
  • RTUs (Remote Terminal Units) & PLCs (Programmable Logic Controllers) – Gather data and execute control commands.
  • Communication Networks – Fiber optics, Ethernet, IEC 61850 standard for fast data exchange.
  • HMI (Human-Machine Interface) – Provides real-time visualization of substation operations.

SCADA System (Supervisory Control & Data Acquisition)

  • Data Acquisition – Collects real-time data from sensors & IEDs.
  • Supervisory Control – Sends commands to circuit breakers, transformers, etc.
  • Alarm & Event Management – Alerts operators to faults and system failures.
  • Historical Data Logging – Stores data for analysis and reporting.
