substationsautomation
Substation automation, also known as SAS, refers to the use of digital systems to monitor, control, and protect electrical substations. It integrates protection, control, measurement, and communications to improve grid reliability, efficiency, and situational awareness. By automating switching operations and data exchange with central systems, SAS enables faster fault detection, isolation, and restoration.
A typical substation automation system comprises intelligent electronic devices such as protective relays and bay controllers,
Key functions include protection and fault isolation, control of circuit breakers and switchgear, measurement and metering,
Implementation involves design, installation, commissioning, integration with other grid management systems, and ongoing maintenance. Cybersecurity and
