摘要	A real time power quality monitoring system based on DSP and FPGA is developed, which is capable of enhancing the recognition rate of power quality disturbances. The monitoring system adopts 8-channel 16-bit AD converter AD7606 controlled by FPGA to acquire the power quality signals synchronously. Then DSP (TMS320DM642) reads the power quality data from the FIFO storage in FPGA and then treats them with double-density dual-tree discrete wavelet transform (DD-DT DWT), and calculates the wavelet coefficient Shannon entropy. At last, a binary tree of SVM is adopted to classify the power quality disturbances. The experimental results indicate that the developed instrument can continuously monitor power quality of eight channels respectively, and the average recognition rate for eight kinds of common disturbance signals can achieve 99.1%.
