In this paper, according to the quality of power supply parameters of aircraft power system and the requirement of parameter test at home and abroad, a set of aircraft power simulation experiment system is designed and developed. On the basis of NI and ADLINK hardware platform, the simulation test system uses Hall Effect sensor to collect data, builds parameter testing system based on Labview software, and completes the test of important parameters such as voltage and current, and makes fault judgment and harmonic analysis of the collected data. Finally, through the comparison and analysis of the data from the experimental platform and the theoretical value, the validity of the experimental test platform is confirmed, which provides a practical tool for the study of the parameters characteristics of the aircraft power system.
