Published: December 2019

Abstract
This paper analyzes the changes of active power flow on the communication channel between regional power grids, summarizes the influencing factors affecting the active power flow, and provides a theoretical basis for the analysis of the combined loop conditions of the electromagnetic loop network between regional power grids. From the perspective of the power angle characteristics of the power system, the relationship between the active power and the power angle of the power supply of the two power networks is derived. The influence of the power angle change on the active power flow in the communication channel between the regional power grids is theoretically analyzed. The correctness of the derivation conclusion is verified by ETAP simulation modeling. Finally, the 35kV grid in Shou County, Huainan, is taken as an example to analyze the influence of power angle on the active power of the loop. The research results show that the change of power angle on the communication channel between regional power grids has a direct impact on the change of active power flow, and the power angle can be used as an important criterion for the electromagnetic ring network.

Abstract
Today, with the rapid development of economy and culture, women have broken through the shackles of “workplace bias” and actively participate in the economic activities of energy-based enterprises. In resource-energy-based enterprises, the effect of female executives on the performance improvement of energy-based enterprises is irreplaceable. Few scholars in resource-energy-based enterprises have focused on the performance improvement of energy-based enterprises by female executives, and there are few studies on the salary and treatment of female executives and the performance of energy-based enterprises. To this end, the thesis takes female executives as the research background, explores the mechanism of female executives’ performance on energy-based enterprises, and promotes the performance of female executives on the performance of energy-based enterprises through innovative compensation management methods. The author uses this research to help resource and energy-based enterprises to develop more suitable programs for women’s executive management and development, and hopes to benefit the development of energy-based enterprises in the industry.

Improving Performance of Fibriform Supercapacitor Based on Cotton Thread by Uncoiling Dip-Coating Procedure
Authors: Ye Xingke , Zhu Yucan , Jiang Hedong , Yue Ziyu , Jia Chunyang 
Published: December 2019

Abstract
Fibriform supercapacitor (FSC) based on cotton thread (CT) produced by dip-coating presents great potential in wearable electronics. However, active materials especially for reduced graphene oxide (RGO) sheets tend to restack on the surface of CT and are difficult to permeate into the inside of CT, thus fading performance. In this work, each cotton yarn (CY) obtained by uncoiling CT is uniformly covered by GO (GO-CY) and RGO coated CT (RGO-UCDCT) is obtained through twisting these GOCYs, followed by subsequent reduction. Uncoiling dip-coating alleviates the restacking of RGO sheets on the surface of CT. Thus, the FSC based on RGO-UCDCTs exhibits superior performance including high volumetric capacitance of 1.85 mF cm-3 and good rate capability. The findings provide a cost-effective procedure of uncoiling dip-coating for improving performance of CT based FSC.

Abstract
This paper investigates the internal and external noise characteristics of a 10kV oil-immersed transformer based on advanced acoustic measuring technology. A kind of fibre-optic hydrophone is installed inside the transformer and four acoustic sensors are placed outside in the air. The noise is measured under the condition of no-load and short circle, and the amplitude and frequency characteristics are obtained. The results show that the amplitude of internal noise is higher and contains more high order harmonics when compared with the external noise. It means the internal noise has a higher signal noise ratio, and contains more information. These results can be used for further research such as transformer noise generating mechanism, transmission regulation, transformer noise controlling.

Published: December 2019

Abstract
The unequal load sharing of double-pinion planetary gear sets (PGSs) would take place because of manufacturing errors. A quasi-static model, suitable for any planet train number and support condition, was proposed considering manufacturing errors. The load sharing ratio of double-pinion PGSs with four planet trains was simulated for various planet position errors, whose results show that the radial planet position error has different effects on the load sharing behavior from simple PGSs. The mechanics for this phenomenon was revealed. The effect of the planet train number on the load sharing behavior in the presence of different planet position errors was then simulated by introducing the equivalent error variable. Finally, the effect of gear eccentricity errors on the load sharing behavior were simulated and some important characteristics were revealed such that the planet eccentricity error has worse impacts than position errors, and the effect of the eccentricity error of sun gear could be eliminated by floating the sun gear.

Authors: Shi Qiuyu , Kang Wei , Mu Xiaobin , Chen Hao 
Published: December 2019

Abstract
Based on simulation, the structure optimization of a Cu evaporation substrate in natural cooling system is conducted, which can be used in power electronics equipment. The relationship between the welding area ratio and stress of evaporation substrate is investigated. The evaporation substrate is one of the most important components in a natural cooling system. Through utilizing phase-transition technology, heat dissipation is realized by a natural cooling system. During operation of evaporation substrate, increase in internal gas pressure, caused by the evaporation of working fluid, leads to deformation of evaporation substrate. Therefore, strengthen-columns are introduced to reinforce the evaporation substrate. Both Pro/E simulation outcomes and experimental results based on structure optimization of evaporation substrate indicate that the optimal design is achieved at a welding area ratio of 1.844%, namely the arrangement of strengthen-columns is 11 × 14 × 3 mm. With this arrangement, the minimum stress on welding surfaces of strengthen-columns and minimum deformation of the evaporation substrate are achieved, which can meet the engineering requirement.
