The development of multiple power voltage harmonic monitor

为对电网中输出的电压谐波进行监测,本文以Silicon Laboratories公司的C8051F020单片机为平台,设计了一种三厢电压谐波监测仪。本仪器可以完成对三路输入信号的电压谐波等参数的监测,同时可实现监测数据的统计存储、与外界通讯、人机交互等功能,具有低功耗、数据处理运算速度快等优点经试验表明:用C8051F020单片机对电压谐波进行监测是一种可行性方案。

In order to monitor and measure the output voltage from the power system,one 3-phase voltage and harmonic measurement instrument is introduced,based on the C8051F020 MCU（Micro Control Unit） from Silicon Laboratories.The instrument can monitor three circuits simultaneously and process the storage of statistics.It has several advantages,such as low power consumption,quick data-processing and etc.The experiment shows that it is a feasible scheme to monitor and measure the voltage harmonic with C8051F020 MCU.
