SCADA and Energy Management Systems

A public, defensive overview of supervisory monitoring and grid-management software.

Electrical safety boundary: this page explains the system conceptually. It does not provide procedures for live electrical work, switching, protection settings, conductor/breaker sizing, substation access or high-voltage operation. Those activities require qualified professionals, applicable codes and utility procedures.

Where this fits

A public, defensive overview of supervisory monitoring and grid-management software.

Core system ideas

SCADA systems collect telemetry and support supervisory control of geographically distributed equipment.

Energy management systems add network applications such as state estimation, contingency analysis and operational planning.

Detailed architectures, access methods and control procedures can be security-sensitive and are intentionally excluded.

Interfaces and tradeoffs

Operators need trustworthy measurements, maintained equipment, current network models, clear procedures and resilient communications. Human decision-making remains important even in highly automated systems.

What organizations measure

Telemetry quality, system availability, alarm performance and model accuracy.
