Study Notes
AC Generation System
- System includes main and emergency generation components.
AC Main Generation
- Ground Power Units (GPUs): Provide 115VAC power to the aircraft on the ground via external receptacles.
- Variable Frequency Generators (VFGs): Supply 230VAC power to the AC network. Four VFGs are installed, two per engine.
- Auxiliary Power Unit (APU) starter/generator: Supplies 230VAC to the AC network.
AC Emergency Generation
- Static Inverter: Provides 115VAC power to the AC inverter busbar, activated when emergency battery 1 is available.
- Ram Air Turbine (RAT) Module AC Generator: Supplies 230VAC power to the emergency AC network if the RAT is fully deployed.
System Location
- VFGs: Installed on the engines (two per engine).
- External Power Receptacles: Located on the forward fuselage.
- RAT Module: Situated on the right side of the aft belly fairing.
- Static Inverter: Positioned on the left side of the avionics compartment.
System Interface
- AC network receives 230VAC from the APU starter/generator.
