Design of Aircraft Power Subsystem Simulation Exciter

In the process of aircraft development, we need to verify the Electrical Management System (UMS) on condition monitoring and control functions of each subsystem digitization, as well as the system management automation. For the subsystem power subsystem requires UMS achieve its AC and DC power supply subsystem bus bar, ground power, battery, rectifier unit and emergency DC generators and other equipment for condition monitoring and fault alarms. In the case of the power supply subsystem actual hardware is not installed, we need to develop a power supply system simulation exciter to completely simulate AC power subsystem, DC power supply subsystem, emergency DC power system, the function of the battery system, AC/DC power distribution system and the interface with UMS, this simulation can real-time monitor the power supply network state, to be able to implant failure information, can record and playback the working state of the power supply system, it is verify UMS for the control of the power supply subsystem, monitoring function. In this paper, the structure and function of the hardware and software are detailed described, with a corresponding software test, as well as verifying the software for each board hardware control and data acquisition functions, and finally introduces the development of the main problems encountered in the process of the system and the key technology. Actual results had shown that the system can effectively monitor and control electrical and mechanical verification management system.
