In-situ structural health monitoring is essential for the early detection of surface cracks at dedicated stress locations. This paper presents a circular-shaped RFID sensor design for wireless surface crack detection on metal. The sensor was designed in the HFSS software tool with a diameter of 50 mm in dimension. Simulation analysis was performed for varying crack depths and widths at sub-millimeter resolution. The sensor is sensitive enough to detect a minimum crack depth of 0.2 mm. The average resonant frequency gradient (Δ) is used to differentiate the varying crack depths and widths. For varying crack depths, the observed Δ values are 2.1 MHz and 6.1 MHz for sub-mm and mm resolution, whereas for varying crack widths, the values are 2 MHz and 7.6 MHz, respectively. Simulated crack samples are fabricated and examined using conventional Eddy USB to illustrate the pros and cons of passive wireless surface crack detection using an RFID-based NDT sensor. © 2023 IEEE.

Better utilization of solar energy applications is possible if solar radiation prediction is made more accurate. Many prediction models were developed from time to time. In this study, an easy and convenient demonstration has been presented to reduce the model complexity with high accuracy in the predicted values. PCA, ANN, ANFIS, and other techniques were discussed in this paper to pre-process the input data. How conveniently do these techniques apply to row data sets to reduce the model complexity? A comparison shows how the model performance degrades due to the use of the large variables data set as well as the removal of key elements. So, this study shows the necessity and importance of pre-processing data and identification of the most significant variables. © 2022

The research conducted for this work has focused on the design and implementation of resilient fractional-order fuzzy integral tilt derivative with filter (FOF-ITDF) controller for renewable-dominated hybrid power system (HPS). The considered HPS employs solar thermal, wind power, diesel engine, aqua electrolyzer, and fuel cell as the distributed generation system. Moreover, flywheel, battery, and ultra-capacitor (UC) are chosen as the energy storage components. The parameters of FOF-ITDF controller are tuned via a hybrid optimization termed as artificial gorilla troops optimizer (GTO) with gradient-based optimizer (GBO). This proposed controller shows enhanced performance over fuzzy proportional–integral–derivative (PID), fuzzy ITDF, and FOF-PID controllers in terms of dynamic as well as steady state. Proposed GTO-GBO: FOF-ITDF controller provides highly robust operation against rate constraint non-linearities, parameter variations, and communication time delays (CTDs). Finally, the performance assessment of the proposed control architecture is also benchmarked over real-power system data via a standard IEEE-14 bus system with its stability evaluation by bode plot. By utilizing the proposed control design, the maximum frequency deviation Δf in the worst situation, i.e., CTD of 0.3 s, is − 0.024 Hz, which is much less and under the admissible range of IEEE standard. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2025.

As an effective non-destructive technology, infrared thermography is often used to detect inner defects in composites. However, non-homogeneous background in the thermal images reduces image quality inevitably. A squeeze and excitation convolutional autoencoder thermography (SE-CAT) technique is introduced for detecting underlying defects. Specifically, the channel attention mechanism assigns weights to different convolutional channels to highlight certain prominent features. As a result, the defect information can be extracted in a targeted manner using the convolutional autoencoder module. Finally, an experiment of carbon fiber reinforced composite materials shows good defect detection performance of the proposed SE-CAT method. © 2024 IEEE.

This paper presents the design of a high-sensitivity chipless RFID sensor tag with a modified depolarizing circular patch for surface crack characterization on metals. The sensor response was realized using a cross-polarization reading, and induced dual resonance frequencies from the incident waves. The circular patch resonates at frequencies of 2.766 GHz and 3.204 GHz with four L-shaped tip-loaded resonators as identification encoders. The surface cracks in vertical, horizontal, and diagonal orientations with varying crack widths and depths in sub-millimeter resolution are simulated. It is observed that the designed patch is sensitive to detect a minimum crack resolution of 0.1 mm for varying crack widths and depths. The average computed gradient of simulated sensor upper frequencies is 27.5 MHz and 58.5 MHz for varying crack depths and widths in vertical orientation. Similarly, varying frequency gradients between dual resonances were observed for other orientations. © 2023 IEEE.

This paper proposed two methods to examine metal particles in fluid using Hall Effect Sensor under the condition of nondestructive testing based on two conditions: test of particles in oil samples, and test of particles in industrial machinery simulation. Hall Effect Sensor was a low-cost device had ability to detect magnetic fields in objects, so this work applied Hall Probe to measure the density of metal in liquid. Hereby, hydraulic liquid was selected to examine because it was one of the most use in industrial machines. By using the sensor, two types of experiment were designed: test of oil sample, and test of simulation process, where the results showed that Hall Effect Sensor had ability to measure particles in both two types of experiment. For oil sample test, the sensor was able to detect metallic powder when the number of contaminants were greater than or equal to 10 milligrams (equivalented to NAS 15 standard). On the other hand, to measure particle in simulation process, magnetic field were generated in two ways, i.e. use of electromagnet, and use of permanent magnet. For using electromagnet as magnetic field source, the result showed that temperature had an influence on metal particle evaluation. Therefore, to get the most accurate value, system's temperature had to employed in calculation process. While, the result of using permanent magnet to generate magnetic field showed that the relationship between output voltage and amount of metal particles were probably in linear form. To apply this method in industrial applications could be an inexpensive way to help officer in detecting metal particle in oil which was able to extend service time of hydraulic liquid properly. © 2024 IEEE.

Neural Computing and Applications 2024年 1-13页

作者： Firdous, Aaquib Tyagi, Arjun Tyagi, V.V. Kumar, Bhavnesh Centre for Energy & amp Environment Malaviya National Institute of Technology Rajasthan Jaipur302017 India Department of Electrical Engineering Faculty of Technology University of Delhi Delhi110007 India School of Energy Management Shri Mata Vaishno Devi University Jammu & Kashmir Katra182320 India Department of Instrumentation and Control Engineering Netaji Subhas University of Technology New Delhi110078 India

The proliferation of renewable energy (RE) and increasing electrical demand stress the existing generation and transmission systems. Moreover, due to environmental concerns, the proper utilization of small-scale renewable distributed energy resources (DERs) has become essential. DERs can play a pivotal role in evolving grids by reducing emissions and improving energy delivery by providing system services like voltage maintenance. Optimal sizing and sitting of these DERs into the distribution system promise various benefits and a viable solution to overcome the limitations of large transmission and conventional generation systems and provide better voltage maintenance. Besides, utilizing realistic data generation from working plants and varying load patterns allows for better insights into power system operations under growing RE. This work presents a profit-based optimal sizing and sitting of DERs into the distribution system while considering environmental costs. An improved Harmony Search algorithm has been applied to optimize the proposed cost-based objective function, which consists of various costs in generating distributed energy while simultaneously considering the environmental expenses incurred due to the release of different pollutant gasses. Also, the generation data of working solar and wind plants and realistic varying loads across seasons, weekdays, and weekend days have been considered to explore real operating scenarios. Efficacy has been verified from the optimization results that illustrate its capability to allocate DERs in conjunction with reduced costs and emissions, facilitating optimal system operations. The algorithm has been tested for two standard distribution systems focusing on reducing overall generation costs, social costs labelled due to emissions, improvement in voltage profile, and reduction in overall losses of the system. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.
