虚拟仪器的飞机变压整流器稳态特性测量研究

摘要

A detection method to detect the DC power quality of the transformer rectifier unit (TRU) provided for the aircraft was presented and the reliable operation of the electrical equipment was ensured. The detection method was based on the requirements of ISO1540-2006 for DC power class A. By analyzing the TRU mathematical model and using virtual instrument technology, the precise measurement for transformer rectifier steady-state of B737 aircraft including the distortion spectrum could be completed. Whether the TRU steady state characteristics meet the standard requirements was verified. This method had high practical significance for the detection of the aircraft steady state characteristics.%为了检测变压整流器(TRU)向飞机提供的直流电的质量，保证飞机用电设备的可靠运行，提出了一种检测方法。该检测方法基于ISO1540-2006对于A类直流电源的要求。通过分析TRU数学模型，采用虚拟仪器技术，可完成对B737飞机的TRU的稳态特性，包括其畸变频谱的精准测量。通过实验，验证了TRU稳态特性是否满足标准要求，实验方法对于飞机TRU的稳态特性检测有很高的现实意义。
