摘　　要：针对电力系统中谐波检测与分析准确度较低的问题,提出了一种以硬件电路设计为主的谐波检测方法。该方法以ARM芯片S3C44BOX为核心,对整个系统的低通滤波、同步采样及A/D转换等模块均进行了具体设计,并结合μC/OS-Ⅱ操作系统和快速傅里叶算法(FFT),使整个系统在可靠性及准确度等方面都有了显著的提高。Considering low accuracy in harmonics detection and analysis,a new detection scheme which hav- ing hardware design based and ARM S3C44BOX chip cored was proposed land the module of low-pass filte- ring,synchronous sampling, A/D conversion and so on were specially designed and the μC/OS-Ⅱ operation system and fast Fourier transformation were integrated in operation to improve both reliability and accuracy of the whole system.
