A Novel NUDCT Resonator Based WPT-MRC System with Anti-Misalignment Function
Authors: Chen Huiying , Pan Zijun
Published: October 2023

In WPT-MRC (Wireless Power Transfer via Magnetic Resonance Coupling) systems, the resonator coils need to be aligned for maximum efficiency, and any misalignment between resonator coils can result in a significant drop in output efficiency. Therefore, improving the anti-misalignment capability of WPT systems is an important consideration for practical applications. The paper has proposed a NUDCT (Non-Uniformly Distributed Coil Turns) coupler with uneven turns that generates a uniform magnetic field to improve anti-misalignment capability of WPT-MRC systems. The proposed NUDCT resonator has been optimized using GA (Genetic Algorithm), and the theoretical analysis of the magnetic field in case of misalignment has been presented. The paper has also validated the WPT-MRC system’s transmission performance using the optimized coil. The results indicate that the magnetic field generated by NUDCT provides better uniformity under misalignment and higher system efficiency.

Authors: Du Changqing , Xiao Di , Ren Zhong , Qi Rui
Published: October 2023

Accurate estimation of the lithium-ion batteries (LiBs) state of health (SOH) is vital for ensuring the safety and dependability of electric vehicles (EVs) throughout their life cycle. However, the traditional neural network estimation has low fitting accuracy, and most research in this field is based solely on normal temperature states. To address this, we propose extracting health factors (HFs) from battery data under different temperature states, employing the Gaussian process regression algorithm (GPR) to estimate SOH. We also examine the influence of various kernel functions on the estimation results of the GPR algorithm.

Published: October 2023

During the erection of multi-bundle conductors of transmission lines, spacers shall be installed between conductors to ensure that the equivalent radius between conductors meets the requirements of relevant standards. During the existing construction process, the installation position of the spacer is marked manually. When marking, only the installation position of the spacer for a single conductor is marked, and the installation posture of the spacer cannot be guaranteed. In this paper, the four-bundle conductor is taken as an example to study the above problems. The studied marking mechanism can ensure that each sub-conductor on the four-bundle conductor has a mark, and the installation position of the spacer is more accurate. The research on the marking mechanism is mainly aimed at its structural stability, installation convenience, marking effect and identifiability, which effectively solves the on-site construction problems.

Over the past 50 years, the burgeoning socioeconomic development in Xiamen has led to a significant decrease in the area and the tidal influx of its coastal waters, resulting in the degradation of its marine ecosystem. Nonetheless, through the implementation of comprehensive management measures such as causeway openings and coastal dredging, Xiamen Bay has seen marked improvements in the water quality of various local waters: dissolved oxygen (DO) levels have stabilized, inorganic nitrogen and reactive phosphate levels have decreased, and the diversity index of large benthic organism communities has increased. These results well demonstrate the effectiveness of Xiamen’s comprehensive coastal waters management in improving its marine ecosystem and environment.

Published: October 2023

Under the background of intensified global climate change, seasonal flood disasters and increasing water consumption are two major challenges to the development of scenic spots. In order to address the conflict between frequent flood disasters and water scarcity, and to mitigate the adverse impacts of climate change, this paper explores strategies of stormwater management in scenic areas. Taking Yesanpo Scenic Area as an example, based on topographic data and hydrometeorological data, this paper uses the SCS-CN model and ArcGIS to simulate the inundation area caused by the design rainfall depth of 2% rainfall frequency in the study area. On this basis, according to the volume capture ratio of the annual rainfall of 85%, green stormwater infrastructure is planned, improving the scenic area’s ability to resist floods that occur once in fifty years and make use of stormwater resources to achieve safe, healthy, and sustainable development.

It is of great significance to study the spatio-temporal evolution of Soil Moisture (SM) for soil water resources and coping with climate change. The fusion product data set between 1978 and 2020 was obtained based on the European Space Agency Climate Change Initiative Soil Moisture (ESA CCI SM) in the Headwater Area of the Yellow River in China. The trend and spatial characteristics of SM in the Headwater Area of the Yellow River during the study period were analyzed by using statistical analysis and B-G diagnostic algorithm, the satellite remote sensing data were verified by using SM observation station data in MAQU. Some conclusions could be drawn: (1) The correlation is significant (R=0.8) between the ground observation data and ESA CCI SM, and the error of the average value of the two was 0.01. ESA CCI SM deviates so little from the measured data that it can be used to characterize variation characteristics of SM in the study area; (2) The SM showed a decreasing trend over the years in the Headwater Area of the Yellow River, the SM content fluctuated greatly for several years but didn’t occur abruptly. The change of SM was most obvious during 2002-2007; (3) The spatial pattern was east west high low and meteorological north low. The seasonal difference was obvious, there was an “M” shaped change trend during the year and the double peaks appeared in May and September. The spatio-temporal distribution of SM was revealed to provide important parameters for water and energy exchange between land and atmosphere.

Published: October 2023

In the context of the global energy crisis and the Russia-Ukraine conflict, considering the current overall situation of international energy consumption, this paper proposes that China establishes a comprehensive control path for energy consumption, focusing on “destocking, controlling incremental growth, and ensuring high quality.” Simultaneously, taking advantage of the construction of “the Belt and Road” initiative, China strives to build a safe and efficient international energy security system to balance energy supply and demand. Based on these efforts, this paper suggests future energy policy and regulatory measures in China to promote rational consumption of energy supply and demand.

The potential for cooperation in the Central and Eastern Europe new energy and electricity market is huge, and cooperation between some countries and Chinese power grid enterprises in the field of new energy technologies is increasing. This paper examines the new energy markets in Central and Eastern European nations as its primary research area. It does so by using a three-order opportunity analysis method to examine the potential for cooperation in various national markets and by tracing the paths taken by power grid enterprises to collaborate with their respective target markets. The authors present a market opportunity analysis evaluation index system to evaluate the electricity markets of 17 countries in Central and Eastern Europe comprehensively, to screen out priority markets for cooperation initially, and to compare and analyse qualitatively the initially chosen target regional markets. dynamically analysing the driving forces behind national markets that are now not conducive to collaboration in the new energy sector, and then altering their driving forces to conform to collaboration opportunities. With the benefit of long-term profit growth, Chinese power grid companies’ successful investigation of new energy cooperation opportunities can serve as a model for other power grid companies looking to enter the Central and Eastern European market and select the most appropriate cooperation avenues in line with the times and technological advancement.

Aiming at the problem that coal gasification coarse slag is seldom used in soil improvement at present, this study takes the waste dump of Hongshaquan No.1 open-pit mine in Zhundong, Xinjiang, as the research object, uses the local coal gasification coarse slag to prepare coal-based soil improver to improve the soil in the study area, and compares it with the improvement effect based on fly ash and domestic sludge to explore the soil improvement effect of different solid wastes. The improvement experiment results show that, in terms of soil particle size, the addition of fly ash and domestic sludge can increase the soil clay content and reduce the sand content, but the effect of coal gasification coarse slag on soil particle size composition is not obvious. In terms of soil nutrients, fly ash will reduce the content of soil organic matter, available potassium and alkali hydrolyzable nitrogen, but increase the content of available phosphorus. Coal gasification coarse residue will increase the content of soil organic matter and available phosphorus, but it has little effect on the content of available potassium and alkali hydrolyzable nitrogen. Domestic sludge will improve the contents of soil organic matter, available potassium, alkali hydrolyzable nitrogen and available phosphorus. In terms of soil pH, fly ash and coal gasification coarse slag will increase soil alkalinity, and domestic sludge will reduce soil alkalinity. The results of the pot experiment in the field showed that the coal gasification coarse slag had the best improvement effect, followed by domestic sludge and finally fly ash. By clarifying the effect of improved materials, this study can better use coal-based solid waste resources in the field of ecological restoration of degraded soil, so as to provide a scientific basis for the ecological reconstruction and pollution restoration of local arid ecologically fragile saline alkali land.

Bozi 7 reservoir is an oil-producing reservoir discovered in Kuqa Depression, Tarim Basin. The oil producing formation is the Cretaceous Bashjiqike Formation, with a depth of over than 7000 m. Using core, thin section, logging, seismic and production data, the geological characteristics of Bozi 7 reservoir are analyzed, and the hydrocarbon charging characteristics and reservoir forming conditions are discussed. The reservoir rocks of Bozi 7 are dominated by fine-medium grained lithic arkose, with average porosity and permeability of 8.7% and 1.2 mD respectively. The fractures are relatively developed and basically unfilled. The pressure coefficient of the reservoir is 1.85, showing abnormal high-pressure characteristics. The production gas/oil ratio is 409 m3/m3. The oil density is 0.8 g/cm3 with low viscosity and high wax content and natural gas has a low methane content. The hydrocarbon mainly comes from Jurassic source rock. The Kuqa depression has mainly experienced 3 stages of hydrocarbon charging, and the hydrocarbon of Bozi 7 reservoir mainly comes from the second stage. Large thrust faults and their derived secondary faults provide pathways for oil/gas migration, while fracture networks promote hydrocarbon charging. High-quality reservoir-seal combinations provide favorable conditions for oil/gas preservation. Experienced rapid charging and accumulation in the later stage, the Bozi 7 hydrocarbon reservoir is formed.
