Dsk Platform Tms320c5402 Chip-based Harmonic Measurement And Analysis

By analyzing the present situations of the electric harmonic monitoring equipments, the prospect of the practical application of Digital Signal Processor (DSP) in the electric power system is discussed in this paper. First of all,,the basic conceptions of harmonic are introduced,and the knowledge of FFT arithmetic which is used to analyse harmonic is also introduced.Secondly,under the condition of knowing the inside structure and function of TI company's originally assembled DSK,an automatic loding and running harmonic measurement analysis instrument which is divorced from emluator and based on the TMS320C5402 chip is proposed.The hardware of the entire design system mostly includes the date collection circuit board with AD73360 chip as its chief part, TMS320C5402 DSK and personal coniputer.The hardware design includes not only the juncture of the designed board where the AD73360 chip is on and the McBSP (Multi-channel Buffered Serial Port) on the DSK board but also the juncture of the DSK and the personal computer after divorcing from emluator.The software design includes FFT arithmetic which is used to analyse harmonic,data collection,Flash erase and programme, data serial transmission.The equipment can measure and analyse harmonic real-timely.
