Smart Operation & Maintenance Solution for Compact Substations

1. Integrated Architecture with Edge-Cloud Collaboration

• Edge Layer: Deploy IoT sensors (e.g., wireless temperature sensors for switchgear monitoring, JN2201 inclination sensors with IP68/IP69K protection) to collect real-time data on equipment status (temperature, vibration, leakage) and environmental parameters (humidity, gas concentration).

• Cloud Platform: Centralize data storage and AI analysis for predictive maintenance and cross-site benchmarking.

2. AI-Driven Predictive Maintenance

• Fault Prediction: Combine historical data with AI algorithms to forecast failures (e.g., transformer overheating, insulation degradation). Achieves ≥99.99% early-warning accuracy, reducing unplanned downtime by 75%.

3. Cybersecurity Resilience

• Trust-Based Framework: Implement a zero-trust model integrating:

• Device Trust Scoring: Monitor device behavior (e.g., abnormal Modbus/DNP3 protocol requests).

• Dynamic Risk Posture: Assess network vulnerabilities pre/post-attack using MITRE ICS ATT&CK framework.

• Embedded Security: Utilize hardened devices (e.g., Schneider MiCOM C264 controller with IEC 61850 compliance and encrypted communications).

4. Unified Operational Management

• Digital Twin: Create a virtual replica of the substation to simulate operational scenarios (e.g., load switching, fault response).

• Centralized Dashboard: Integrate data from SCADA, environmental monitors, and security systems, enabling:

• Automated report generation (50+ inspection items).

• One-click sequential control.

5. Sustainable & Efficient Resource Use

• Energy Optimization: Deploy AI algorithms to balance loads dynamically (e.g., adjusting transformer taps based on real-time demand), improving grid efficiency by 3%.

• Space-Saving Design: Leverage compact substations occupying 1/10–1/5 of traditional space, with modular components for rapid deployment.
