WAMS/PMU Data Pre-Processing and Compression
Li Hu, Shengsuo Niu, Liang Zhi · Advanced materials research · 2014
With the Wide Area Measurement applications, a large number of experimental PMU data was generated. In order to analyze, transmit and apply the data efficiently, by understanding the characteristics of the PMU data in this paper, pressing the data with the Waveform difference method, then using Huffman algorithm to compress the data. Compare the data pre-processing before and after, compression ratio has been further improved.
