With the wide-area measurement WAMS applications, a large number of PMU measured data was generated. In order to analyze, transmit and apply the data efficiently, this paper uses the waveform difference and the diminishing coordinates to process, than uses the recursion Huffman to compress. By pre-processing and improving compression algorithms, it optimizes the algorithm, improves the compression ratio and shortens compression time.
