| 1 | A new coordinated backup protection scheme for distribution network containing distributed generation显示文摘This paper proposes a new backup protection scheme,named coordinated backup protection(CBP)scheme,for distribution networks containing distributed generation.The proposed protection scheme takes into account the issues faced by traditional backup protection,such as difficulty in setting parameters and complex cooperation,and considers the features of distribution networks,such as changeable power flow because of high penetration of distributed generation sources and insufficient measuring quantities.The CBP scheme includes two aspects:coordinated substation protection and regional master substation protection,who also work as nearby backup protection and remote backup protection respectively.The two protections support each other by local information coordination and regional information sharing,in order to improve the reliability of fault identification.The configuration principles and performances of the proposed backup protection scheme are addressed in the paper.Different fault conditions in the IEEE 14-node system have been used to illustrate and verify the feasibility of the CBP scheme. | Jinghan He Lin Liu Fanfan Ding Changcheng Li Dahai Zhang | 2017 | Protection and Control of Modern Power Systems2017，2，1： | 3 |
| 2 | Two-dimensional CoNi@mesoporous carbon composite with heterogeneous structure toward broadband microwave absorber显示文摘Constructing composites with heterogeneous structure and dual loss mechanism shows great potential in designing microwave absorbers.In this work,two-dimensional cobalt and nickel alloys@mesoporous carbon(CoNi@MC)composites were constructed via using CoNi layered double hydroxide@mesoporous polydopamine(CoNi LDH@MPDA)as sacrifice template.During the pyrolysis process,the MPDA is transformed into mesoporous carbon coated the surface of CoNi LDH that is further reduced to CoNi alloys.The mesoporous structure is conducive to the multi-reflection of electromagnetic waves and facilitates optimizing impedance matching.Heterogeneous interfaces between CoNi alloys and mesoporous carbon induce interface polarization.Multiple attenuation mechanism promotes the electromagnetic waves conversion.The maximum reflection loss of CoNi@MC composite is−70.86 dB and the widest effective absorption bandwidth is 7.74 GHz covering almost the entire Ku band.This strategy will be a guidance for designing electromagnetic absorbers. | Yun Qiu Haibo Yang Fanfan Hu Ying Lin | 2022 | Nano Research2022，15，9： | 1 |
| 3 | Impedance Modeling and Stability Analysis of Dual Active Bridge Converter with LC Input Filter显示文摘The dual active bridge(DAB)converter is gaining more and more attention in various applications such as energy storage systems,electric vehicles and smart grids.To improve the quality of the input current,a LC filter is often cascaded at the input side of the DAB converter.However,there are instable problems of this cascaded system due to the impedance interactions of the DAB converter and the LC filter,although the DAB converter is stable at the individual operation mode.To assess the stability of the cascaded system of the DAB converter and the LC filter,the impedance model of the DAB converter is firstly developed based on generalized state-space averaging method.The developed impedance model can be used to accurately predict the stability of the DAB converter with its LC input filter.Based on the stability analysis,the optimum filter parameter design guideline is determined.The impedance model and stability analysis are validated by the simulation and experimental results. | Fan Feng Xin Zhang Fanfan Lin Hoay Beng Gooi | 2018 | CES Transactions on Electrical Machines and Systems2018，2，3： | 0 |
| 4 | Seasonal features of topside scale height based on COSMIC measurements显示文摘Plasma scale height is an important parameter of topside ionosphere and contains information about ionospheric physics and dynamic. We investigated the seasonal features of vertical scale height with the electron density profiles from COSMIC. We found that vertical scale height around 660 km at middle latitudes generally has larger values in winter than in summer and had similar structures at March Equinox and September Equinox no matter daytime or nighttime. Bands of large vertical scale height appear at night around ±36° magnetic latitude in all seasons except summer for low solar activity, and mostly appear in winter for moderate solar activity. Vertical scale height in the middle latitudes generally has smaller values for moderate solar activity than that for low solar activity around 660 km, and has smaller values in the daytime than at night. | Fanfan Su Jian Lin Fuying Zhu Yiyan Zhou Jian Yang Liangchen Hu | 2017 | Geodesy and Geodynamics2017，8，5： | 0 |
