Research And Design Based On ARM Embedded Harmonic Detector

Grid in the running process will encounter a lot of interference signal, wherein the power harmonic interference is an important branch of. We can for the acoustic study and know " harmonic " this word, at the same time we also can understand " harmonic " development course is long. This paper is aimed at how to detect the harmonic in electric power system are discussed, based on the current popular embedded system development of a harmonic detection apparatus.This paper analyzes the domestic and foreign research on harmonic writings, papers, based on the research of harmonic detection algorithms, discussed several kinds of commonly used analysis method. This is a fast algorithm Fu Liye, designed the harmonic detection of the main program, realize the harmonic spectrum analysis, and the popular Ipiq detection algorithm for circuit design and simulation. In terms of hardware, using ARM9development board S3C2410, this system integrates a rich interface circuit, easy realization of embedded Linux driver development and application development. The embedded Linux made of underlying system development, transformation of the Bootloader, mastery of the content, to the new interface hardware write driver, to further strengthen the chip manual research, to realize the combination of hardware and software of the advantages of working. Can detect harmonic purpose.On the public power grid harmonic appearance quality have important influence on the study of harmonic, still need further deepen.
