The Design of Power Quality Detecting System Based on ADSP-BF606

Abstract

The low cost and the multi-function have been the main contradiction of power quality detecting devices. For it, this paper designs a power quality detecting system based on the latest ADI’s ADSP-BF606 dual-core processor. With the high-speed AD7606 chip, the system achieves real-time data acquisition, processing, and analysis. The hardware design makes the system highly integrated, lower cost and easy to be integrated into the enterprise information management system. The fast flourier transformation with window and interpolation is adapted to detect harmonic, and S-Transform is used to detect and locate interferences automatically and quickly, wavelet package transform and binary tree support vector machine are also used to make interference classifications. Experiment results show that this design meets the requirements and different algorithms make the system more automatic and intelligent. The system with low cost and the multi-function is better than others.
