| 摘 要： | 对电网谐波的周期性特点进行了研究，讨论了基于快速傅立叶变换（FFT）的电网谐波监测方法。设计了一款双CPU控制的远程电网谐波监测系统，对系统软硬件、上位机软件设计进行了详细的说明。利用数字信号处理器（DSP）进行测量数据的采集和FFT变换运算，得到的测量结果传给微控制器（MCU）实现数据的存储、显示和上报，上位机通过远程通信接口实现远程监测。上机测试表明，工作稳定、监测效果良好。

| Abstract: | Cyclic characteristics of harmonic was studied, a method for monitoring harmonic of power system was discussed based on the Fast Fourier Transform （FFT） . A remote harmonic monitoring system of power system controlled by dual-CPU was designed, hardware and software of this system and software of host computer were introduced in detail. Digital Signal Processor （DSP） was used for acquiring data of measure and FFT calculating, the results were transferred to the Micro Controller Unit （ MCU ） for data storing, displaying, and uploading, host computer monitored the data through remote communication interface. Tests show that this system is stable, the monitoring is well. |
