| 摘 要： | 谐波分析是电能质量测试中的重要环节，准确的测试为谐波的补偿提供了重要的依据。该文着重研究了不同步采样下谐波分析的理论，给出了C语言的仿真，并比较了不同窗函数的特点。对FFT算法做了改进，将浮点的运算改为定点的运算，使其更能符合项目的特点。

| Abstract: | Harmonic analysis is power quality test of an important part of accurate test for harmonic compensation provided an important basis. This article focuses on the non-synchronous sampling Harmonic Ana]ysis under the theory, given the C language simulation, and compare the different characteristics of the window function. FFT algorithm to do the improvements, the floating-point operations will be designated the operator, to make it more consistent with the characteristics of the project. |
