Abstract
Recently, need of power stability and reliability has been increased as the spread of the sensitive electronic loads. Therefore, the power quality(PQ) problems become the hot Issue of public interest in these days. Many kinds of algorithms have been studied for the monitoring of PQ problems using the monitoring algorithms with RMS or FFT scheme, but it is still not enough to measure all of the PQ problems. This paper proposed the application of discrete wavelet transform(WT) for the PQ problems monitoring with the Introduction of WT theory, and the design of PQ monitoring data acquisition system Is described with some experimental results to verify the validity of the proposed PQ monitoring algorithm.
