Substation Automation

Substation automation is key for smarter, more reliable power grids. With the evolution of technology, real-time measurement is vital. While SCADA shifts to synchrophasor technology and PMUs, a substation automation system utilizes Intelligent Electronic Device (IED) data for control.

What is a Substation Automation System?

It integrates hardware and software for local and remote electrical system monitoring and control.

Key Benefits & Functions

• Manages interlocks; provides global/local alerts.
• Pinpoints distribution system fault locations.
• Enables proactive maintenance.
• Offers cost savings, enhanced performance, and safety via digitized fiber-optic communication, replacing copper.

Modern IEDs (RTUs, reclosers, PLCs) gather, analyze data, detect abnormalities, and command switches to rectify issues. This optimizes asset management and boosts operational efficiency.
