초록
This paper presents an efficient data acquisition scheme to obtain a minimum CPU memory, optimized communication speed, and simplified program source code in a monitoring system. It is different in the number of utilized data from the conventional method which acquires every raw data. The proposed method uses only restrictive data required to reconstruct the original signal. The basic principle is to apply the FFT-IFFT method in data transferring process. To verify the high-performance of the proposed scheme, computer-aided simulation and experiments using a PV power monitoring system are carried out. It also presents the analyzed results the relationship between FFT's order and Gibb's Phenomenon.
