| Abstract: | Considering the features of electric energy data transmission in electric power system, the RAY-Period compression algorithm was researched and analyzed, which consisted of RAY compression algorithm in combination with period compression algorithm. Combining bitmap compression method, it expounded the compression theory of RAY algorithm and period algorithm respectively. At last, it presented the program flow of RAY-Period compression algorithm, and finally realized the algorithm by C language. The tests result shows that this algorithm could effectively compress electric energy data and could effectively reduce the network flux with great practical value. |
