    A new adaptive voltage protection scheme suitable for distribution networks with potential distributed generation (DG) inserts is proposed in this paper. Firstly, the intelligent electronic devices (IEDs) are utilized to store relevant line parameters, obtain real-time voltage and current data, and facilitate communication among the IEDs. On this basis, the adaptive voltage primary and backup prot... View full abstract»

    In this paper, the different singularity characteristics of differential current of transformer differential protection under inner-zone and out-zone faults are analyzed while the current transformer is saturated. Then, using grille fractal, a new approach to prevent maloperation of transformer differential protection is proposed. Combining the proposed approach with an adaptive generalized morpho...

    The discrete Fourier transform (DFT) is still a widely used tool for analyzing and measuring both stationary and transient signals in power systems. However, the misapplications of DFT can lead to incorrect results caused by some problems, such as aliasing effect, spectral leakage, and picket-fence effect. This paper establishes a relationship between DFT-based spilled energy and harmonics/noninte... View full abstract»

    This paper presents two-stage detectors for spectrum sensing in cognitive radio networks. The first stage consists of multiple energy detectors, where each energy detector (ED) has a single antenna with fixed threshold for making a local binary decision. If required, the second stage comprised of ED with adaptive double threshold is invoked. The detection performance of the proposed scheme is comp... View full abstract»

    The one-step predictive dead-time control circuit proposed in this paper consists of a dead-time detection circuit and an analog optimization circuit. The detection circuit, which can be manufactured on the same die as the synchronous MOSFET of the buck converter, provides an accurate detection signal that indicates body diode conduction. The proposed dead-time optimization circuit is an analog ci... View full abstract»
