In this paper,a power quality monitor system which is based on the TMS320VC33 and FPGA realizing is put forward,and through combining wavelet with Fourier transform,we can realize the function of monitor the power quality on line.

• 提出了基于TMS320VC33和FPGA实现的电能质量监测系统,采用基于小波变换和傅立叶变换相结合的方法实现在线监测电能质量的功能。
