DSP based measurement control device for power quality detection and reactive power compensation

An integrative measurement control device based on DSP was developed for power quality detection and reactive power compensation. The device realizes real time data processing using complex sequence FFT algorithm and bit reversed indirect addressing mode in DSP. The discrepancy in timing sequences of data storage between DSP and MCS-51 is solved; the USB and SCI data transfer issue is treated correctly. Using the developed software, data analysis chart and curve are generated quickly. Real time dynamic reactive power compensation is realized. Practical operation indicates that the device can measure various parameters of power system quality quickly and precisely, up to 60 day power system data are stored and not lost even in power outage, data uploading is accurate, and real time characteristic of reactive power compensation is good.
