A real-time UWT-based intelligent fault detection method for PV-based microgrids
(Elsevier Science Sa, 2019)
In this paper, a new un-decimated wavelet transform (UWT)-based fault detection method is proposed to overcome the limitations of WT-based methods in real-time applications. For the first time, UWT method is used to detect ...
Assesment of Power Quality Disturbances For Grid Integration of PV Power Plants
Power Quality problems, which have become an important consumer issue in recent years, are defined as changes in voltage, current, or frequency in the power system. Among the factors affecting energy quality in grid-connected ...
Signal processing-based automated fault detection methods for smart grids
(Springer Science and Business Media Deutschland GmbH, 2020)
Automated fault detection methods (AFDMs) are required to provide a more reliable and stable power system operation and protection. The faults in distributed generators (DGs) connected to the grid must be cleared on time ...
An improved automated PQD classification method for distributed generators with hybrid SVM-based approach using un-decimated wavelet transform
Artificial intelligence (AI) approaches are usually coupled with the wavelet transform (WT) for feature extraction to classify the power quality disturbances (PQDs). Therefore, selecting a useful WT-based signal processing ...
DWT-Based Islanding Detection Method for DFIG-typed WTs
(Institute of Electrical and Electronics Engineers Inc., 2020)
In this study, it is aimed to image the transparent objects by applying the phase shifting technique to lateral shearing digital holographic microscopy. In order to extract the phase information from interference patterns ...
A new signal processing-based islanding detection method using pyramidal algorithm with undecimated wavelet transform for distributed generators of hydrogen energy
(PERGAMON-ELSEVIER SCIENCE LTD, 2022)
Machine learning-based fault detection methods are frequently combined with wavelet transform (WT) to detect an unintentional islanding condition. In contrast to this condition, these methods have long detection and ...
