Architecture Framework
Smart-grid architecture is not a single design — it is a set of layered decisions about communication protocols, data models, security boundaries, and operational workflows. The SGAMS architecture framework organizes these decisions into five functional layers, each with defined standards, integration points, and failure modes.
The layers are: field instrumentation, substation automation, SCADA and data acquisition, operational decision support, and enterprise integration. Each layer has its own protocol requirements, latency tolerances, and security zonation rules.
Protocol Engineering
The shift from proprietary vendor protocols to open standards — particularly IEC 61850 for substation automation and IEC 60870-5 for telecontrol — is the defining technical transition in grid modernization. It is not a plug-and-play migration.
IEC 61850's Generic Object Oriented Substation Event (GOOSE) messaging operates at the Ethernet layer with sub-millisecond timing requirements. Deploying it without understanding network switch configuration, multicast group management, and protection relay firmware behavior leads to failures that appear during fault conditions — not during testing.
The SGAMS protocol engineering framework covers migration sequencing, test environment design, interoperability validation, and post-deployment monitoring for IEC 61850, DNP3, Modbus TCP, and ICCP implementations.
SCADA Integration
SCADA systems in transmission and distribution environments are long-lived investments — typical operational lifespans of 15–25 years. Architecture decisions made today must accommodate protocol evolution, cybersecurity requirements, and operational expansion without requiring platform replacement.
The SGAMS SCADA integration framework is built around the IEC 61968/61970 Common Information Model (CIM). CIM provides the data modeling foundation for interoperability between SCADA, EMS, DMS, and GIS systems — enabling operational data exchange without custom integration code at every boundary.
Smart Grid Visualizer
The SGAMS Grid Visualizer provides real-time topology mapping across distributed node networks. It is designed for operational teams who need situational awareness across large transmission zones, not dashboard aesthetics.

Standards Coverage
The SGAMS framework references the following standards as the primary engineering basis for smart-grid architecture work:
- IEC 61850: Communication networks and systems for power utility automation
- IEC 61968/61970: Common Information Model for distribution and transmission management
- IEC 60870-5: Telecontrol equipment and systems (DNP3 compatibility layer)
- IEEE 2030: Guide for smart grid interoperability
- NERC CIP: Critical Infrastructure Protection standards for bulk power systems
- IEC 62351: Security for power systems communications
We do not treat standards compliance as a checklist. We treat it as an engineering baseline from which deployment-specific decisions are made.
Engagement Starting Points
Grid architecture engagements typically begin with one of three entry points: an existing SCADA replacement programme where protocol migration is the critical path, a new renewable integration project that requires topology changes, or a cybersecurity remediation programme that reveals architectural gaps.
If any of these describe your situation, the appropriate starting point is a technical discovery session — not a product evaluation.
