Electric Power Transfer Ac Network TRIZ Cases
- Source Side Converter Frequency Damping for Grid Stability
A control system operates source side converters in a frequency damping mode to stabilize AC voltage at the connecting point.
- HVDC Disconnector Support Structure Merging Components
Single-piece support structure merges mechanical and electrical functions to eliminate assembly time and complexity.
- Voltage-Coordinated Control for AC/DC Distribution Systems
A voltage-coordinated control method stabilizes DC voltage in hybrid distribution networks using droop models.
- AC-DC Interface Auxiliary Windings for Fast Fault Isolation
A short-circuiting device across auxiliary transformer windings lowers current stresses to enable prompt AC breaker opening during pole-to-ground faults.
- Single-Stage Three-Phase Power Conversion Merging Rectification and DC/DC
A single-stage three-phase power conversion device merges rectification and DC/DC modules to reduce component count.
- Voltage Balancing in Voltage Source Converter Director Switches
Dynamic switching timing based on clamp capacitor voltage levels balances director switch units, preventing instability from voltage imbalances.
- DC Transmission Network Fault Isolation via N-1 Security System Segmentation
A DC transmission network control method opens N-1 security systems to reduce fault current before line circuit breakers operate.
- Offshore Wind Turbine Low-Frequency Transmission System
An AC-to-AC converter changes variable generator output to fixed low frequency, reducing equipment size and cost for long-distance transmission.
- VSC-HVDC Converter Adaptive Switching for DC Fault Current Limiting
Dynamic switching coefficient adjustment suppresses bridge-arm currents to limit DC fault currents, reducing circuit breaker capacity requirements.
