Requirement of green supply with higher quality has been consumers' demand around the
globe. The electrical power system is expected to deliver undistorted sinusoidal rated …

The increasing trend towards renewable energy sources requires higher power quality (PQ)
at the generation, transmission and distribution systems. The PQ disturbances are produced …

Power quality (PQ) interest has increasingly evolved over the past decade. The paper
surveys the application of signal processing, intelligent techniques and optimization …

In this paper, we discuss the compression of waveforms obtained from measurements of
power system quantities and analyze the reasons why its importance is growing with the …

An algorithm based on the concept of adaptive notch filter (ANF) is proposed for estimation
of power system frequency. The ANF is a second-order notch filter that is further furnished …

In this paper, a new algorithm based on processing differential current is proposed for digital
differential protection of power transformers by considering different behaviors of the …

This paper presents a new approach for power quality time series data mining using S-
transform based fuzzy expert system (FES). Initially the power signal time series disturbance …

In power quality monitoring systems, a large volume of data is generated. A compression
method should be used to perform the storage of data more efficiently. The present study …

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 …

In this paper, an embedded zerotree wavelet transform (EZWT)-based technique is
employed for the data denoising and compression in the smart grid (SG). The EZWT is a …
