0.2S三相多功能电能表的研究
Research on the 0.2S Three-Phase Multi-Functional Power Meter
摘要
Abstract
The principle of the three-phase multi-functional power meter with the measure of harmonic electri cal energy is introduced. This meter using the advanced BF531-ADSP processor and the sampling chip AD73360, applying the complicated arithmetic of quasi-synchronous sampling, the arithmetic of filter and the a rithmetic of windowing and interpolation FFT, performs the three-phase power measure of 0. 2S precision and the harmonic analysis. The actual test results show that it has the advantages of high precision, fully functional and high reliability.关键词
