【摘要】 提出了用嵌入式计算机为主CPU ,以高档单片机为从CPU ,通过双口RAM交互数据的总体硬件方案 ;利用LabVIEW软件构建了测量与分析平台 ,并研制开发了实用性样机。详细分析了三相低压电网不对称负载非正弦电路的谐波功率、功率因数的测量及其实现方法。此外对样机的高速采样、数据传送、波形录制及频谱 (谐波 )分析等功能均作了详尽的介绍 ,最后给出了实验及其数据的处理结果更多还原

【Abstract】 A hardware project in collective is put forward in.A embedded computer board is used for master CPU exchanging data through a dual port RAM with an advanced microcontroller which is slave CPU.For the more,the practical prototype model is developed.The measuring and practical techniques of harmonic power and power factor of tri phases low voltage power system with asymmetrical load and non sine electrocircuit is analysed in detail.Moreover, the prototype model functions of high speed sampling,data transmission,waveform records and frequency spectrum analysis are elaborated.At last,the result of the experiment and its data are presented.更多还原
