About this skill

Problems It Addresses

Grid questions are rarely isolated: a fault in primary equipment can involve protection, stability, maintenance, and safety; new energy and storage integration can change power flow, protection behavior, and grid-connection requirements. Practitioners often need to classify whether an issue belongs to equipment O&M, protection analysis, safety procedures, storage integration, or power communications, while keeping standard versions, field operability, and risk boundaries in view.

How It Works

  • Intent routing: maps keywords to workflows such as equipment faults, relay protection, stability rules, virtual power plants, V2G, hydrogen, and drone inspection.
  • Knowledge-base search: uses search(source="kb", ...) to retrieve standards, cases, and literature; uses fetch(type="media_id") when source details are needed.
  • On-demand references: loads files like references/fault-diagnosis.md or references/standards-index.md to speed up diagnosis or standard lookup.
  • Structured output: organizes fault analysis by symptoms, likely causes, handling steps, and safety notes; standard interpretation highlights scope, key clauses, and version changes.
  • Fallback handling: when evidence is weak, it separates standard-based findings from general inference instead of presenting experience as regulatory truth.

Boundaries

It is suitable for technical consulting in grid design, O&M, protection, safety, storage, carbon trading, and digitalization. It should not replace safety work permits, formal design reviews, statutory interpretation, or final engineering decisions. For personal safety, incident response, or grid acceptance, follow the latest standards, regulator requirements, and site procedures.

Use Cases

  • An operator investigates a 110kV transformer gas relay trip by checking oil chromatography and likely internal faults.
  • A protection engineer assesses direction element and distance protection adaptation after new energy and grid-forming storage connect.
  • A project engineer compares GB/T 31464-2022 with earlier versions to explain changes in grid operation rules.
  • A storage planner compares electrochemical, pumped storage, and compressed air storage using grid standards and cost-benefit factors.

Best For

  • Grid O&M engineer: needs to link transformer or GIS fault symptoms, protection operation, and maintenance safety measures.
  • Protection engineer: needs to verify protection settings, coordination rules, and adaptation to new energy or grid-forming storage.
  • Design-institute engineer: needs to locate standards for customer service projects, supply schemes, and microgrid interconnection.
  • New-energy plant operator: needs to understand storage interconnection, dispatch communication, and safety-procedure risks.
