摘　　要：针对电力部门对电网运行质量进行监测的要求,设计了一种以高精度的浮点运算DSP(TMS320C32)为核心的电力系统谐波监测仪。应用加窗分裂基快速傅立叶变换算法进行数据分析,并选用双路异步串行通讯PC16552进行测量参数的设置和传送等工作。实践证明本装置能够准确而且快速地监测电力系统各次谐波参数,具有使用方便、功能丰富等实用价值。A power system harmonic monitoring instrument is designed based on the float operation DSP of high precision because power department＇s demand to monitor the running quality of electric power net work. It analyzes data with interpolating windowed split-radix FFT, and set up measureing parameter and transmit with double synchronous serial communication. Practice shows that monitoring instrument can monitor power system＇s various harmonic parameters. It has practical value as convenient use and abundant function.
