This paper proposes a hybrid approach combining Wigner-Ville distribution (WVD) with convolutional neural network (CNN) for power quality disturbance (PQD) classification. Firstly, WVD technique is developed to transfer 1D voltage signal into 2D image file, followed by CNN model the Then, feature maps are extracted automatically from file and different patterns variables on CNN. A set of synthetic signals, as well real-world measurement data, used test proposed method. The high...
A microwave sensor with a coplanar waveguide semilumped meander open complementary split-ring resonator (MOCSRR) is proposed to analyze the dielectric properties of liquid. The method operates at subgigahertz frequencies and uses small volume liquid (>0.08 mL) on substrate-integrated slot container. resonance reflection coefficient notch frequency its magnitude in decibels are observed for complex permittivity ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...
In order to slow down the transformer thermal fault caused by aging of insulating oil during operation oil-immersed transformer, this paper uses simulation software Materials Studio simulate process mineral based on conditions under actual working and adds nano SiO2 particles for modification its rate analyze principle. The results show that surface groups can react with active produced in oil, thus reducing interreacting slowing cracking materials. Moreover, amount acetylene modified is...

Harmonics and subharmonics in power systems distort grid voltage, reduce the quality of power, affect security grid. Rapid accurate harmonic separation from voltage is crucial technology to ensure that operate safely stably. The blind source method based on independent component analysis has been used separate components voltage. As acquired only a single channel, it classed as single-channel problem. Hence, this paper proposes for combines ensemble empirical-mode decomposition FastICA....
This paper proposes a novel, two-stage and hybrid approach based on variational mode decomposition (VMD) the deep stochastic configuration network (DSCN) for power quality (PQ) disturbances detection classification in systems. Firstly, VMD technique is applied to discriminate between stationary non-stationary PQ events. Secondly, key parameters of are determined as per different types disturbance. Three statistical features (mean, variance, kurtosis) extracted from instantaneous amplitude...
