Abstract
Because of three-phase unbalanced bearing power,the accuracy of AC harmonic analysis and electric parameters monitoring is very important for control strategy of reactive power compensation. Taking TMS320F240 DSP as the system’s microprocessor, the system for analysis of AC harmonic and monitoring of electric parameters of power network of high-power device was developed. The paper introduced the functions of the system in details, and placed emphasis on the structure of soft hardware taking DSP as single-CPU and a new type of data acquisition system(DAS)-MAX125 as the A/D converter and synchronizing AC sample.
