A prototype induction generator VSCF system for aircraft

Conventionally the hydromechanical driver is used to regulate the variable speed of aircraft engine to provide approximately constant speed for aircraft generator system. DC link variable-speed constant-frequency (VSCF) electrical power generator system is the advanced system available today. Compared with DC link VSCF system, a compact induction generator VSCF (IGVSCF) system presented in this paper can increase efficiency and reliability and further reduce the maintenance man-power per flight hour. The performances of IGVSCF system have been simulated by the computer program and the experimental operation has been done by a prototype IGVSCF system. These simulated results and experimental tests prove that the IGVSCF system is superior to DC link VSCF and hydromechanical driver.
