Electric Power Transfer Ac Network TRIZ Cases
- Over-voltage Protection System Using Segmented Detection
Segmented detection circuits trigger self-powered gate drives to bypass high-voltage circuits, reducing detection delay and ensuring reliable protection.
- Power Converter Short-Circuit Unit for AC Line Fault Protection
A power converter arrangement uses a phase-connected short-circuit unit to generate symmetrical faults without grounding.
- Controllable Commutation Inductor for HVDC Inverter Failure Recovery
A controllable commutation inductor adjusts leakage inductance via a parallel switch to manage converter valve operation.
- Modular Converter Capacitor Selection for Uniform Loading
A modular converter control method prioritizes unipolar capacitors during specific current phases to maintain uniform sub-module operation.
- MVDC Collection Grid With Modular DC-DC Converters
Modular DC-DC converters in an MVDC collection grid transfer power from generator-rectifier subsystems to a bipole HVDC transmission system.
- Offshore Power Delivery via DC Transmission
DC transmission lines reduce energy losses over long distances while keeping submerged equipment volume low.
- Series-Connected Limiter Cells for DC Voltage Overvoltage Protection
Modular limiter cells with capacitors and resistors drop voltage across series-connected stages to manage electrical stress in DC networks.
