Single Network Parallel Feeding Arrangements TRIZ Cases
- Inverter Frequency Control for Islanding Detection
A controller applies command frequency variations to an inverter waveform to detect islanding conditions within a distributed generation system.
- Intelligent Electronic Device Fast Bus Transfer Synchronization
An intelligent electronic device monitors power supply parameters to execute fast bus transfers between sub systems.
- Power Converter Transient Ride-Through Control
Current and voltage limiters constrain DC bus parameters during grid fluctuations, preventing converter damage from overcurrent conditions.
- Current-Impressing Inverter Instantaneous Reserve via PLL Phase Error
A current-impressing inverter generates an instantaneous reserve setpoint signal from a phase error of its PLL control loop.
- Inverter Control for Power Quality and Output
A modulation controller adjusts reactive power to maintain linear inverter behavior.
- Carrier Signal Phase Adjustment for Harmonic Reduction
Adjusting carrier signal phase in power plant converters reduces electrical output harmonics below regulatory thresholds.
- Hierarchical Microgrid Control for Seamless On-Off Grid Transitions
A hierarchical microgrid control system manages power conversion and accumulation to maintain frequency and voltage stability.
- Asynchronous Generator Hydro Turbine AC-AC Converter
An asynchronous generator paired with an AC-AC converter manages variable water flow rates in small hydroelectric plants.
