SCADA Anomaly Interpretation & Response Prioritization
Interpret SCADA alarms and prioritize grid operator response actions in seconds
What You Can Do
You can feed Claude raw SCADA alarm dumps and sensor readings from multiple substations or feeders, and receive structured diagnostics that distinguish between nuisance alarms, maintenance signals, and critical grid threats. Claude correlates temporal sequences, applies domain logic around voltage tolerance and protection relay timing, and recommends immediate diagnostic steps or escalation decisions—enabling you to reduce response time and avoid unnecessary field crew dispatch.
Features
Parse simultaneous readings across substations/feeders to identify cascading failures versus isolated faults
Analyze alarm sequences and transient timing to distinguish equipment faults from sensor malfunctions
Apply grid operator knowledge including voltage sag tolerances, reactive power limits, and protection relay timing thresholds
Recommend diagnostic steps and validation tests before dispatching field crews or escalating to duty engineers
Identify genuine threats requiring immediate load shedding, switching actions, or emergency protocols
Analyze alarm threshold settings after adjustment complaints to confirm appropriate sensitivity
Troubleshoot and interpret loss-of-signal scenarios from remote terminal units
Analyze voltage or frequency oscillation patterns to identify damping or resonance issues
Example Output
Example 1: Nuisance Alarm Identification
Input: Substation A reports low voltage alarm (118V @ 138kV bus) with simultaneous high reactive power draw. Neighboring substations B and C show normal voltage (127V–130V). Alarm triggered 3 seconds after capacitor bank switching.
Output:
- Priority: Low (nuisance alarm)
- Root cause: Capacitor bank transient; voltage dip is localized and expected
- Recommended action: Monitor next two 5-minute scan cycles; no field dispatch required. Verify capacitor bank switching sequence in SCADA logs.
Example 2: Equipment Fault Detection
Input: Breaker 12-47 trips unexpectedly during normal loading (no weather event, no grid disturbance). Current drops to zero. Voltage remains stable at 128V. Protection relay shows overcurrent and instantaneous trip signal logged 45ms before breaker operation.
Output:
- Priority: Medium–High (equipment concern)
- Root cause: Likely breaker mechanical fault or relay sensitivity drift; actual fault current was not present
- Recommended action: (1) Pull relay calibration report for breaker 12-47, (2) Schedule substation maintenance visit to inspect breaker contacts/coils, (3) Recloser remains blocked until crew clears
Example 3: Grid Stability Threat
Input: Multiple substations report frequency dip (59.2 Hz) + 8% voltage sag lasting 200ms. East feeder showed reactive power spike; Southwest feeder disconnected via protection. Real power flow increased 40% on North corridor in last 30 seconds.
Output:
- Priority: Critical (grid stability)
- Root cause: Southwest feeder fault triggered cascade; North corridor now overloaded
- Recommended action: (1) Immediate: Shed 25 MW from North corridor via interruptible load protocol, (2) Expedite field crew to Southwest feeder fault location, (3) Notify dispatch supervisor for emergency switching plan, (4) Monitor frequency recovery—may require additional load shedding if frequency continues declining
