摘要
傅里叶变换是分析飞机供电系统谐波含量等参数的主要方法,但该方法计算量大、实时性差。在此通过分析国军标谐波参数标准,利用Lab VIEW虚拟仪器技术,构建了简单实用的程序分析飞机供电系统谐波。相对传统分析方法可以快速得到供电系统的谐波特征参数,使用方便、实时性好。通过传感器、信号采集模块等建立了某型飞机地面电源测试系统,对采集的系统波形采用Lab VIEW谐波分析程序,可以实时显示系统的谐波含量等特征参数,判断出该系统的供电质量。
The Fourier transform is the main method for analyzing harmonic component and other parameters of airplane power supply system,but it has the disadvantages of more calculation and poor real？time performance. A simple and practical program was established in this paper to analyze harmonic of airplane power supply on the basis of virtual instrument technology by analyzing the military standard of harmonic parameters,which can quickly get the characteristic parameters of harmonic wave in power supply. The program has convenient application and perfect real？time performance. A ground testing system of power supply for a certain airplane was built up with sensors and signal acquisition module. With the harmonic analysis program Lab？VIEW for acquired system waveform,the real？time harmonic content and other characteristic parameters can be displayed and the power supply quality of the system can be judged.
