Data transfer is extremely important in any Data Acquisition System (DAS). Power system operation involves enormous volume of data transfer between field devices (or generating stations) and data centre (or Load Despatch Centre). Data compression is an extremely popular in communication as there is a reduced energy requirement for transferring compressed information. Power line communication is still in operation for data transfer between different substations and Differential Code Shift Keying (DCSK) modulation scheme is extremely popular in the majority of the available power line communication modems. Differential Binary Encoding Algorithm (DBEA) is a low computational approach which can give high compression ratio with repetitive slow varying data array. As majority of available data can be compressed successfully, this work focuses on the development of DBEA compressed data transfer system suitable to transfer data over power line. At the encoding end, a large data array corresponding to different practical data is compressed by DBEA before transferring the string through DCSK. From the superchirp being obtained, compressed string is extracted and is decoded to obtain actual data array at decoding end. As DBEA is implemented and tested successfully at low level microcontrollers, it is possible to extend this work for practical applications.
