Data traffic has grown exponentially with the rapid development of Narrowband Internet of Things (NB-IoT) technology. Nonorthogonal multiple access (NOMA) and mobile edge computing (MEC) are essential technologies to enhance the performance of NB-IoT networks. This article proposes a new hybrid NOMA offloading strategy, allowing an Internet of Things (IoT) device to execute NOMA with other devices...Show More
This study concentrates on the dynamics of electrical arcs on ice-accreted outdoor insulators under DC voltage, essential for ensuring the reliability of electrical grids in extreme icy conditions. Employing a comprehensive methodology that combines ice accretion experiments, theoretical analysis, and simulation modeling, the research aims to explore the characteristics and attenuation mechanisms ...Show More
The aging discrimination method of composite insulators has always been the focus of research in the electric power field. This paper obtained the SEM data set (CIS-SEM data set) by collecting 550 composite insulator samples in operation in a coastal area in China. By analyzing SEM images, this paper determined the aging characteristics of the SiR surface of composite insulators at different aging...Show More
As the service life increases, the latent defects of power cables gradually become apparent, threatening the normal operation of cable lines. This study simulates two typical defects of power cables under laboratory conditions, the thermal aging and the insulation scratch. The grounding current signals of cable specimens are collected under three defect levels. The Variational Mode Decomposition (...Show More
An online monitoring and condition evaluation method for HVAC power cable is proposed using the feature extraction of magnetic field signals. Five typical defects including outer sheath damage, copper shielding damage, core wire breakage, insulation scratch, and thermal aging are experimentally simulated. The magnetic field of different specimens is measured under the operating condition. The feat...Show More
Submarine cables are widely used in submarine power grid systems, and the operating environment is complex and harsh. Anchor damage is the most fatal factor affecting the safe and stable operation of submarine cable lines. In this paper, the finite element analysis is used to study both the electric and magnetic field distribution of submarine cables to evaluate the degree of anchor damage. Proces...Show More
Thermal aging of insulation at landing section is one of the major sources of submarine cable failure. This paper proposes a novel method for thermal aging evaluation of submarine power cables based on the detrended fluctuation analysis (DFA) of grounding current. Samples under different aging degrees are fabricated and the grounding current of each sample is tested. The distortions in grounding c...Show More
