Automatic Monitoring Devices, Dsp & Cpld-based Network Parameters

In this paper , based on the study of TTU (Transformer Test Unit) theory and the special theories of DSPs (TMS320F206) and CPLD (XC95108) , the hardware configuration and calculating the parameters on the Equipment for Testing Power Parameters Based on DSP&CPLD is discussed. And the realization of the DSPs's hardware and software , FFT arithmetic , harmonic analysis , the testing in lacking phase and engendering the pulse for sampling solved by CPLD are analyzed in detail. It's in the end of the paper that the method on minishing the errors is discussed.
