Power System Automation & Communication Protocols

Q: What is the distinction between GOOSE and MMS messages in IEC 61850?

GOOSE messages operate directly at the Ethernet data link layer (Layer 2) for ultra-fast peer-to-peer relay trip and interlock exchanges (< 4 ms). In contrast, MMS messages use the TCP/IP stack (Layer 7) for client-server communication between IEDs and SCADA supervisory stations.

Q: How do you guarantee zero communication downtime in SAS networks?

We deploy PRP (Parallel Redundancy Protocol), where every Ethernet packet is duplicated and sent simultaneously over two completely separate LANs, or HSR (High-availability Seamless Redundancy) in rings, delivering zero-millisecond failover if a cable or switch fails.

Q: Can you handle complete point-to-point testing with the grid operator?

Yes. We manage the entire lifecycle: telemetry point mapping, gateway protocol configuration, and live point-by-point end-to-end testing with utility and transmission operators.

Complete Substation Automation System (SAS) and power plant architectures compliant with IEC 61850, featuring deep expertise in industrial communication protocols (DNP3, IEC 60870-5-104), modern SCADA HMIs, and zero-loss PRP/HSR networks.

The Complexity of Digital Substations

Modern digital substations require seamless integration of multi-vendor IEDs across station and process buses, requiring determinism, zero packet loss, and full compliance with regional utility and grid operator telemetry mandates.

Our End-to-End Integration Capability

We design, engineer, configure, and commission complete SAS architectures covering process, bay, and station levels. We deliver ultra-fast GOOSE messaging, reliable MMS reporting, telecontrol gateways, and high-availability SCADA HMIs with millisecond SOE timestamping.

Proven multi-vendor interoperability across SEL, Siemens, Schneider, GE, and ABB platforms.
Zero recovery time on network communication links using PRP and HSR protocols.
Flawless telemetry commissioning and sign-off with national grid control centers.
Ergonomic, situational-awareness SCADA HMIs with real-time diagnostic reporting.
