MACOS

Devices, signals, and protection in one test environment.

Virtual WMUs, PMUs, IEDs, and power-system models recreate a digital substation. The dashboard shows device states and traffic while repeatable tests connect waveform generation to protection behavior. It runs on a PC without dedicated simulation hardware, for isolated test environments. The screens show simulated devices running in GridCORE.

Read the same signal in time and phase.

Three-phase waveforms

Inspect six voltage/current channels and harmonics. Configure faults, frequency deviation, noise, and synchronization errors.

Phasor diagram

Compare voltage/current magnitude and phase, alongside frequency and measured impedance before and after a fault.

MACOS

Change fault conditions. Inspect protection behavior.

Connect overcurrent and distance protection to trip delays and breaker opening. Track impedance against Mho zones on the R-X plane and evaluate correct operation, failure to trip, slow trip, overreach, and underreach. Overcurrent curves follow IEC 60255-151 and IEEE C37.112. In v0.1, distance protection targets three-phase loops; ground/line-fault residual compensation remains future work.

Inspect traffic. Design the test sequence.

Protocol inspection

Inspect SV/GOOSE continuity, retransmission, and state. The platform also covers MMS, R-SV, C37.118, IEC 104, DNP3, PRP, and HSR.

Scenario editor

Arrange faults, breaker operations, and frequency changes on a timeline. Reuse YAML and patterns; record PCAP, COMTRADE, and event logs.

A Rust engine connected to interactive analysis tools.

The Rust engine connects three-phase waveforms, symmetrical-component fault analysis, and two-source line models to protocol encoders. Dedicated device threads combine sleep and spin scheduling; Linux supports real-time priorities. Timing depends on the operating system and runtime environment.

The desktop app combines Tauri 2 with React and TypeScript. WebSocket channels carry waveforms, phasors, and status to separate visualization modules. A Rust backend with Tokio and Serde connects to TanStack, Zustand, and i18next for state handling and localized interfaces.

L2 transport uses BPF on macOS, AF_PACKET on Linux, and Npcap on Windows, alongside TCP/UDP. R-SV supports HMAC-SHA256 authentication and AES-256-GCM encryption. YAML, PCAP/COMTRADE, JSON Lines, and Prometheus metrics connect repeatable tests to result analysis.

Repeatable tests. A defined verification scope.

Use the platform for substation training, protocol analysis, protection-setting studies, and PMU/PDC integration tests. CLI and headless modes support automated runs; YAML scenarios can generate CSV/COMTRADE datasets for protection research. L2 protocols require access to the relevant network environment.

Protocol verification in v0.1 includes BER-structure comparisons against public reference SV/GOOSE captures. These checks do not constitute certified IEC 61850-10 conformance. Dynamic timing, session behavior, and interoperability with specific vendor devices require separate testing.

The HIL connection path can feed an external GOOSE trip back into simulation state. Physical-relay interoperability validation, expanded live-traffic monitoring, and digital twins are tracked as subsequent development stages.
