4. Component Description_____________________ The emergency generation system is mainly composed of: - a Constant Speed Motor/Generator (CSM/G) including a hydraulic motor and an AC generator, - a Generator Control Unit (GCU). A hydraulic motor drives the emergency generator. A servo valve speed regulator controls the speed: it transforms the oil flow of the Blue hydraulic system into constant speed for the generator. When emergency conditions are met, this Blue system is supplied by a Ram Air Turbine (RAT).
NOTE : The Blue hydraulic system is supplied by an electric pump in normal____ configuration.
A. Constant Speed Motor/Generator
(1) Hydraulic motor: - Powered by the Blue hydraulic circuit (RAT in emergency configuration ; electrical hydraulic pump in test), - speed regulation by servovalve, - integrated solenoid control valve.
(2) AC generator: - Three phase 115V/200 V - 400 Hz (12000 rpm), - output power: 5 KVA continuously, - oil cooled.
