Research on Three-Phase Power Quality Disturbance Signal Compression Method
摘要
Abstract
This paper presented a new method of three-phase power quality data compression based on compressed sensing.First of all, the three-phase power quality disturbance signals within the time of t were converted into one-dimension signals within the time of 3t;Then, the traditional theory of the multi-band fusion problem was applied to the design of the compression perception sparse matrix to construct a sparse matrix;Lastly, the Gaussian random ma-trix was chosen as the observation matrix and the OMP algorithm as the reconstruction algorithm to reconstruct the three-phase power quality disturbance signals and simulate them through MATLAB.The experiment results showed that the method could effectively compress the three-phase power quality data,to implement the simultaneous pro-cessing of the three-phase power quality disturbance signals, and detect multiple performance parameters.关键词
