Testing & Monitoring — Wide-Area Protection Platform

C-RAS

Centralizes wide-area remedial action scheme (RAS) logic on a high-performance platform — with built-in fault scenario playback, IEC 61850 GOOSE messaging, and AVEVA PI integration for transmission utilities managing constrained corridors.

Centralized RAS Development

Build and maintain RAS algorithms in a high-level Microsoft .NET environment instead of per-device logic, replacing device-by-device updates with centralized deployment. 

Real Fault Data Validation

Replay historical system events directly into RAS algorithms via fault scenario playback and GOOSE Blaster simulation, validating logic against real-world conditions before deployment.

Sub-Millisecond Wide-Area Signaling

IEC 61850 GOOSE messaging provides the sub-millisecond inter-substation communication required for wide-area protection.

What C-RAS Delivers

Distributed RAS architectures push protection logic into individual substation devices, making every logic change a device-by-device update and every test cycle slow to execute. C-RAS centralizes that logic on SISCO's Unified Analytic Platform (UAP), giving protection engineers one high-performance environment to develop, test, and deploy wide-area protection schemes.

  • High-level RAS development in a Microsoft .NET environment — faster to build, debug, and update than distributed device programs
  • Fault scenario playback that replays historical system events directly into RAS algorithms for pre-deployment validation
  • GOOSE Blaster-generated multi-device fault simulation for rigorous testing without live substation interaction
  • IEC 61850 GOOSE messaging for sub-millisecond inter-substation signaling
  • Standards-based device configuration via Substation Configuration Language (SCL) files, supporting multiple manufacturers with no custom integration
  • ICCP-TASE.2 (IEC 60870-6) and web service interfaces connecting C-RAS to existing SCADA and EMS environments with no custom middleware
  • Deployed on SISCO's Unified Analytic Platform (UAP), which also supports synchrophasor processing for Wide Area Measurement Systems (WAMS)

Technical Specifications

C-RAS runs as an application on SISCO's Unified Analytic Platform (UAP), combining a redundant real-time runtime with historian integration, simulation tooling, and standards-based interfaces for wide-area protection deployment.
    • Deployed on SISCO's Unified Analytic Platform (UAP) — high-performance runtime, historian integration, simulation environment, and development toolchain
    • IEC 61850 GOOSE messaging for sub-millisecond signaling; Substation Configuration Language (SCL) file-based device configuration
    • IEC 60870-6 TASE.2 (ICCP) and web service interfaces for SCADA/EMS integration
    • AVEVA PI System integration — system events and application responses historized automatically for fault analysis and performance trending
    • C37.118 synchrophasor data stream processing support for Wide Area Measurement Systems (WAMS) applications
    • Redundant, real-time runtime architecture for continuous operation
