1. Grid Digital Transformation
Grid digital transformation centers on core power system operations and is an enterprise strategy that uses digital technologies to drive business change with the goal of business-value innovation. The process emphasizes integration with distribution network digital infrastructure to improve real-time sensing, widespread interconnection, and the security and controllability of the grid.
2. Fully Automated Switchgear
Fully automated switchgear integrates artificial intelligence into traditional switchgear to improve equipment safety and reliability. The AI entity encompasses control systems, machinery, components, and software. AI development must address both system-level behavior and individual components, covering hardware and software.
3. Digitized Complete Equipment
Distribution network automation requires a large number of digitized devices. Their use and manufacture still involve humans, but they aim to reduce repetitive heavy labor for operators. Advanced electronic devices can sensitively detect line faults, reduce manual inspection time, and improve the speed of power restoration.
4. Six Technical Characteristics of Digitized Devices
- Intelligent grid equipment: advanced electronic fully automated switchgear that senses line faults, analyzes causes, makes local decisions, and controls switch opening and closing.
- Grid faults include line faults and equipment faults. Fully automated switches can perform grid fault detection.
- Fully automated switches provide trip protection; during distribution line faults, relay protection and safety automation quickly isolate the circuit to protect equipment from damage.
- Distribution line faults are mainly caused by overvoltage or overcurrent that trigger protection devices, resulting in outages. Fully automated switches should withstand strong fault current impacts.
- Deploying fully automated switches in urban distribution networks enables rapid fault location, automatic fault isolation, and timely restoration of power in complex grids.
- Fault early warning.
Fully automated switches can detect imminent grid faults and, because switchgear gathers multiple cables, monitor the cables themselves to collect node information. Using the switches' monitoring capabilities to track grid operating conditions allows for big data analysis, generation of diagnostic reports for all electrical equipment, early prediction of operational faults, and implementation of intelligent operation and maintenance for the power system.
