Design and Implementation of Generator Drive Characteristics Simulation Device for Civil Aircraft

According to ground laboratory airworthiness verification test requirements of the civil aircraft electrical power system in CCAR25, it is necessary to simulate the drive characteristics of the aircraft power unit to the generator. In this paper, a generator drive characteristics simulation device is designed to meet this requirement. According to the requirements of steady state speed control accuracy and dynamic response characteristics, which have an important impact on the simulation of drive characteristics, the core functional modules of the device have been designed and implemented in detail, and the device is applied to the ground laboratory airworthiness verification test of the civil aircraft power system. The tests showed that the device has excellent drive characteristics, as well as the advantage of simple structure.
