KeyStone Locate

KeyStone Locate

KeyStone Locate is Shapstone’s fault localization and restoration support module within the KeyStone Grid Intelligence platform. By fusing real-time SCADA and IED telemetry with physics-constrained models, Locate pinpoints faulted sections and recommends optimal switching sequences to restore service.

Key capabilities

• Real-time fault localization. Locates faults on feeders and lateral networks using distributed telemetry, breaker status signals, and fault indicators.
• Estimated fault distance with confidence. Provides fault distance estimates with confidence intervals per feeder segment, reducing unnecessary crew dispatch.
• Automated switching recommendations. Generates optimal sectionalizing and restoration switching sequences to minimize outage scope and duration.
• OMS integration. Seamlessly integrates with outage management systems to automatically dispatch crews to the correct location.
• Real-time alerts. Sends instant alerts to field crews and control centers when faults are detected and localized.

How it works

Locate ingests real-time data from SCADA systems, protective relays, fault circuit indicators, and distributed sensors. Its AI models combine this telemetry with a physics-aware network model to produce a probabilistic fault location estimate. The module then simulates multiple switching scenarios and ranks them by restoration speed, crew efficiency, and system stability.

Value for utilities

Electric utilities using KeyStone Locate typically see:

• 30–70% reduction in fault localization time.
• 25–40% reduction in average outage duration (SAIDI).
• Fewer unnecessary crew dispatches through confidence-ranked estimates.
• Improved crew safety with precise, telemetry-backed location guidance.

Locate integrates with the broader KeyStone platform — Forensics for post-event analysis, Live for continuous situational awareness, and Assure for decision validation.
