For stable power system operation, various system parameters like voltage, current, frequency, active and reactive power etc. are monitored at a regular basis. These data are either stored in the database of the system or transmitted to the monitoring station through SCADA. If these data can be compressed by suitable data compression techniques, there will be reduced memory requirement as well as lower energy consumption for transmitting the data. In this paper, an algorithm based on Arithmetic Coding is developed for compressing and decompressing such parameters in MATLAB environment. The compression ratio of the algorithm clearly indicates the effectiveness of the algorithm.
