| 1 | Simulation Researches on Influence of Different Axial Magnetic Fields on Anode Activity in High-current Vacuum Arcs显示文摘纵向磁场对阳极活动的控制效果对于大电流真空电弧成功开断十分关键。采用建模仿真的方法,分析不同纵向磁场强度对阳极活动的影响。基于大电流真空电弧模型,仿真得到不同纵向磁场强度下输入阳极的能流密度分布,并以此作为阳极活动模型的边界条件,得到不同磁场强度下的阳极熔化、蒸发情况。仿真结果表明:对于工频电流(50Hz)电弧,阳极温度的最大值出现7ms时刻附近;随着纵向磁场的增大,阳极表面温度、饱和蒸汽压、阳极蒸汽流量都相应减小;随着纵向磁场的增大,熔化半径增大,但是熔化深度减小,改善了阳极的烧蚀情况。 | WANG Lijun JIA Shenli CHEN Bin ZHOU Xin YANG Dingge SHI Zongqian | 2012 | 中国电机工程学报2012，32，13： | 8 |
| 2 | Fine-tune chiroptical activity in discrete chiral Au nanorods显示文摘Accurate researches on the surface plasmon resonance(SPR)-based applications of chiral plasmonic metal nanoparticles(NPs)still remain a great challenge.Herein,a series of chiral plasmonic metal NPs,e.g.,chiral Au nanorods(c-Au NRs),c-Au@Ag core–shell,and c-Au@TiO_(2) core–shell NRs,with different chiroptical activities have been produced.Plasmonic circular dichroism(PCD)bands of c-Au NRs can be precisely tailored by tuning the longitudinal SPR(LSPR)and amount of Au NRs as seeds.Besides,a shift of PCD bands within ultraviolet–visible–near infrared ray(UV–vis–NIR)region can also be achieved through the functionalization of a shell of another metal or semiconductor.Interestingly,chirality transfer from c-Au core to Ag shell leads to new PCD bands at the near-UV region.The tuning of PCD bands and chirality transfer are confirmed by our developed theoretical model.Developing chiral Au NRs-based chiral plasmonic nanomaterials with tunable chiroptical activities will be helpful to understand the structure-direct PCD and to extend circularly polarized-based applications. | Guangchao Zheng Sulin Jiao Wei Zhang Shenli Wang Qinghua Zhang Lin Gu Weixiang Ye Junjun Li Xiaochen Ren Zhicheng Zhang Kwok-yin Wong | 2022 | Nano Research2022，15，7： | 2 |

| 8 | Analysis of influence of a novel inductive fault current limiter on the circuit breaker in 500 kV power system显示文摘A contribution to the engineering application of a proposed 500 kV fault current limiter(FCL)is presented.A new type of FCL composed of a highly coupled split reactor(HCSR)and fast switches is proposed.When the circuit breaker(CB)in series with the FCL in the 500 kV power system interrupts the limited fault current,the rate of rise of the recovery voltage(RRRV)reaches a value much higher than the rated value.Based on a simplified equivalent single‐phase circuit,the influence of the new FCL on the interruption procedure of the CB is simulated and discussed.The simulation results show that the high RRRV is caused by high‐frequency resonant oscillations between the HCSR and its parasite capacitance.Analysis indicates that when the reactance of the FCL is close to the short circuit reactance of the system,the RRRV will reach the highest value.To solve this issue,we proposed installing a shunt capacitor with the FCL.Simulation results showed that the RRRVunder all fault modes could be restrained to below the rated value by introducing a certain shunt capacitor. | Qiang Tang Shenli Jia Yanzhe Zhang Shixin Xiu Wenxiong Mo Yong Wang Haibo Su | 2021 | High Voltage2021，6，6： | 0 |
| 9 | Interruption Characteristics of High-speed Switches in 500 kV Fault Current Limiter with High Coupled Split Reactance显示文摘A 500 kV high-voltage AC fault current limiter(FCL)based on a high coupled split reactor(HCSR)is pro-posed by the National key R&D project team.Low impedance under normal conditions and high impedance under short-circuit conditions are accomplished by the cooperation of HCSR and high-speed switches.High-speed switches play an important role in current limiting processes,thus interruption characteristics of the high-speed switch in the 500 kV FCL are studied in this paper.The simulation model of the FCL and the external equivalent power grid are established.The short-circuit current and recovery voltage characteristics of the high-speed switch in FCL are simulated.The results show that maximum DC component of the short-circuit current of the high-speed switch reaches 91%,the maximum peak value is 118 kA,and the longest arcing time is 14.8 ms.There is a discontinuity in the curve of the short-circuit current peak and arcing time as a function of the short-circuit occurrence time;the peak recovery voltage of a single break of the high-speed switch has a maximum value of 87.5 kV under a three-phase ungrounded short-circuit condition,and the rate of rise of recovery voltage is o.22 kV/s.The recovery voltage peak shows a period change with the short-circuit occurrence time,and the period is 10 ms.The effects of the shunt capacitor value and short-circuit ground resistance on the recovery voltage of high-speed switching are also studied.The research can be used for reference by R&D personnel and testersof500kVFCLs.Index Terms-Fault current limiter(FCL),high coupled split reactor(HCSR),high-speed switch,interruption characteristics,short circuit current. | Yanzhe Zhang Shixin Xiu Qiang Tang Shenli Jia Bo Chu Wenxiong Mo Yong Wang Haibo Su | 2023 | CSEE Journal of Power and Energy Systems2023，9，4： | 0 |
| 10 | A new dynamic bacterial foraging optimization and its application on model reduction显示文摘Inspired by the foraging behavior of E.coli bacteria,bacterial foraging optimization(BFO)has emerged as a powerful technique for solving optimization problems.However,BFO shows poor performance on complex and high-dimensional optimization problems.In order to improve the performance of BFO,a new dynamic bacterial foraging optimization based on clonal selection(DBFO-CS)is proposed.Instead of fixed step size in the chemotaxis operator,a new piecewise strategy adjusts the step size dynamically by regulatory factor in order to balance between exploration and exploitation during optimization process,which can improve convergence speed.Furthermore,reproduction operator based on clonal selection can add excellent genes to bacterial populations in order to improve bacterial natural selection and help good individuals to be protected,which can enhance convergence precision.Then,a set of benchmark functions have been used to test the proposed algorithm.The results show that DBFO-CS offers significant improvements than BFO on convergence,accuracy and robustness.A complex optimization problem of model reduction on stable and unstable linear systems based on DBFO-CS is presented.Results show that the proposed algorithm can efficiently approximate the systems. | Shenli Wu Sun’an Wang Xiaohu Li | 2015 | International Journal of Modeling, Simulation, and Scientific Computing2015，6，2： | 0 |

| 13 | Numerical Investigation on Influence of Wire Dimension on Energy Deposition Stage in Single Wire Electrical Explosion显示文摘The initial stage of wire array Z-pinch,i.e.the energy deposition stage in single wire electrical explosion,plays a very important role in the performance of the whole Z-pinch process.In this paper,this stage was modeled and simulated.Based on a mathematic model coupled with external circuit,the influence of wire dimension on the waveforms of current and voltage and the voltage-peak time in the energy deposition stage was studied.The calculated specific power indicates that time of the energy deposition extends with wire length quadratically.For normal wire dimension of wire array Z-pinch,the energy deposition time decreases slowly with the decreasing wire diameter,until approaches a minimum depended on the wire length. | LI Yao SHI Zongqian WANG Kun WU Jian JIA Shenli LI Xingwen | 2013 | 高电压技术2013，39，10： | 0 |
