Development of Harmonic Measuring Instrument Based on DSP
Measurement and analysis of harmonic have great significance because that confining and eliminating harmonic is an urgently demand to assure power system to run safely and protect the safety of devices and person. This paper introduces the principle of harmonic measurement using FFT of dicimation in time (DIT) and gives formulas to compute parameters of harmonic. And based on this, the harmonic measuring instrument based on DSP chip TMS320VC5402 is designed including design and frame diagram of hardware and software in this paper. The harmonic measuring instrument has functions of auto measuring, running parameter and module setting, data displaying and printing and so on. The results of the experiment indicates that this measuring instrument has characters of fast operation, high precision, simple structure, cheap cost, easy operation, strong display etc.
