分布式发电大量接入配电网时，会在电能质量等方面对配电网的运行产生影响。对于家庭或小微企业用户，电压偏移、电压波动对其用电影响最为直接。本文以电压偏移以及电压波动为指标，开发了基于快速傅里叶算法（FFT）的实时电能质量监测模块，利用51系列单片机进行了仿真测试，结果验证了该监测模块的可应用性。

Due to considerable distributed generation access to the existing distribution network,it will influence the network operation in many regards such as power quality. For small customers,the influence of voltage devia-tion and voltage fluctuation is supposed to be most significant. A real-time power quality monitoring module is pro-posed for computing voltage deviation and voltage fluctuation based on FFT algorithm. Based on the simulation test by using 51 series MCU,the results show that the proposed module is applicable.
