In this paper, an embedded zerotree wavelet transform (EZWT) based technique is employed for the data compression in the smart grid (SG). The EZWT is a simple but effective data compression algorithm. It yields fully embedded code by generating the bits in order of importance. This technique does not need any training, pre-stored tables or codebooks, and(More)
In this paper, a framework for the smart grid (SG) power quality (PQ) monitoring system based on wavelet packet decomposition (WPD) is proposed to detect PQ disturbances. This paper proposes an effective technique for PQ disturbances detection based on the inter- and intra-scale correlation of the wavelet packet coefficients. The wavelet packet coefficients(More)
A technique based on wavelet packet decomposition (WPD) is proposed for the analysis, denoising, and compression of power system data in the smart grid (SG) communication. WPD is an expansion of wavelet decomposition (WD) tree algorithm to a full binary tree. The main advantage of WPD is better signal representation by finding the best tree from a number of(More)
In this paper, the application of space vector pulse width modulation (SVPWM) technique is proposed for a two-phase full bridge voltage source inverter (VSI) having reduced number of switches. For the switching sequence, only symmetric SVPWM is considered in order to minimize the harmonic contents of the output current. By using software, three level(More)
Image segmentation plays a very important role in many image understanding and computer vision techniques. Over the last few decades image segmentation techniques have been advanced significantly, though a few quantitative evaluation techniques have been proposed. Most of the segmentation evaluation techniques are largely subjective that means the(More)
