针对当前电网中大量电能质量信号需要进行频谱分析的问题，本文基于FFT算法，利用Atmega 128L单片机大容量flash存储器、高速数据处理能力以及AD转换器，LCD12864液晶显示屏、结合串口通信模块，设计了一款电网扰动信号频谱分析仪，进行了实际测试，结果表明该分析仪功耗低，性价比高，实用性较强，可用于电网质量实时监测时进行频谱分析。

In view of the current power grid requires a lot of power quality signal spectrum analysis of the problems, this article is based on FFT algorithm, using the large capacity flash memory Atmega 128 l MCU, high-speed data processing ability and AD converter, LCD12864 LCD display, serial communication module, designed a grid disturbance signal spectrum analyzer, the results show that the analyzer, low power consumption, can be used in the power grid q...
