| 1 | Research and Development on Short Gap Streamer Discharge Simulation Methods显示文摘流注放电是间隙放电研究的重要内容与切入点,仅靠实验手段仍然无法获得流注放电的微观机制及放电通道内的全部物理参数,因此,数值仿真成为推动流注放电理论发展的一种重要方法。文章阐述了短间隙流注放电仿真的流体模型及其假设,分析了数值仿真算法中的3个难点问题,即粒子输运方程的准确求解、不规则区域中泊松方程的快速求解以及光电离项的快速求解。在回顾流注放电数值仿真领域解决上述3个难点问题的历史过程与取得进展的基础上,提出了解决上述问题的可能途径与努力方向。 | ZHUANG Chijie ZENG Rong | 2012 | 中国电机工程学报2012，32，22： | 17 |
| 2 | Experiment on Leader Propagation Characteristics of Air Gaps in UHVDC Transmission Towers Under Positive Switching Impulse Voltages显示文摘Rapid developments in EHV/UHV transmission systems require a deeper understanding of the mechanism of long air gap discharge.Leader propagation is one of the main processes in long gap breakdown.In this paper,the leader propagation characteristics of real size±800 kV UHVDC transmission tower gaps under positive switching impulse voltages(185/2290μs)are investigated.An integrated observation platform consisting of an impulse voltage divider,a coaxial shunt,a high-speed video camera,and a set of integrated optical electric field sensors(IOES),is established.The waveforms of impulse voltage,discharge current,electric field variation at specific positions,and time-resolved photographs of discharge morphology are recorded.Axial leader velocity and the relationship between leader advancements and injected charge are obtained.The typical value of leader stable propagation velocity is 1.7–2.2 cm/μs,which varies slightly with the gap length and applied voltage amplitude.The leader velocity in the re-illumination process is much higher,and is seen as varying from 5 cm/μs to 30 cm/μs,with an average value around 10 cm/μs.The charge in leader channel per unit length is 20–40μC/m,which illustrates a near-direct proportion relationship between discharge current and leader velocity.The observed parameters are important for further simulation of the tower gap breakdown processes. | Xuan Zhou She Chen Hai Wang Rong Zeng Chijie Zhuang Junjie Yu Yujian Ding | 2015 | CSEE Journal of Power and Energy Systems2015，1，3： | 12 |
| 3 | Survey of recent progress on lightning and lightning protection research显示文摘Lightning and lightning induced effects have significant influence on many aspects affecting the public, whichmakes the research of lightning and lightning protection very important. However, due to the strong randomness andcomplex discharge mechanisms of lightning, the understanding of lightning is still far from satisfactory.

The goals of this study are to givereaders an overall introduction to the recent progress in lightning and lightning protection research, and to motivatethem to conduct further studies to address the unsolved problems in lightning-related research. | Rong Zeng Chijie Zhuang Xuan Zhou She Chen Zezhong Wang Zhanqing Yu Jinliang He | 2016 | High Voltage2016，1，1： | 6 |
| 4 | Measurement of Electric Field of Space Charge Under Positive Lightning Impulse Voltage显示文摘很多绝缘问题本质上都与电场相关,电场测量是高电压领域的重要研究手段。空间电荷导致电场畸变是流注理论的基础,因此定量测量空间电荷的泊松电场对于研究空气间隙的放电机制有重要意义。利用光电集成电场传感器测量了1m棒–板间隙未发生放电条件下各点的轴向电场,并与数值仿真结果进行对比,验证了电场传感器进行定量测量的可靠性;对3种电极条件下1m棒–板间隙空间电荷区域外部轴线上各点的电场时域波形进行测量,将空间电荷形成的泊松电场与外加电压形成的拉普拉斯电场分开,定量测量了不同电压幅值下、不同空间位置的泊松电场幅值与变化规律。研究结果为建立并验证空间电荷模型奠定了基础。 | GENG Yinan ZENG Rong ZHUANG Chijie WANG Feng | 2012 | 中国电机工程学报2012，32，22： | 5 |
| 5 | Recent studies in satellite observations of three-dimensional magnetic reconnection显示文摘Magnetic reconnection is a main process converting the magnetic energy into thermal and kinetic energy in plasmas. It is one of the fundamental problems of crucial importance not only to space plasmas physics and space weather studies,such as the solar flare,coronal mass ejections and magnetospheric substorms,but also to the stability analysis in magnetically confined fusion. In general,except for cases with periodical boundary conditions,three-dimensional(3D) magnetic re-connection occurs on magnetic separatrices generated by magnetic nulls. Here we briefly introduce/review the theories and some recent satellite observations of 3D magnetic reconnection. Topics to be further studied are also discussed. | XIAO ChiJie WANG XiaoGang PU ZuYin MA ZhiWei ZHAO Hui ZHOU GuiPing WANG JingXiu LIU ZhenXing | 2007 | Science China(Technological Sciences)2007，50，3： | 4 |
| 6 | A Positivity-Preserving Scheme for the Simulation of Streamer Discharges in Non-Attaching and Attaching Gases显示文摘Assumed having axial symmetry,the streamer discharge is often described by a fluid model in cylindrical coordinate system,which consists of convection dominated(diffusion)equations with source terms,coupled with a Poisson’s equation.Without additional care for a stricter CFL condition or special treatment to the negative source term,popular methods used in streamer discharge simulations,e.g.,FEMFCT,FVM,cannot ensure the positivity of the particle densities for the cases in attaching gases.By introducing the positivity-preserving limiter proposed by Zhang and Shu[15]and Strang operator splitting,this paper proposes a finite difference scheme with a provable positivity-preserving property in cylindrical coordinate system,for the numerical simulation of streamer discharges in non-attaching and attaching gases.Numerical examples in non-attaching gas(N_(2))and attaching gas(SF_(6))are given to illustrate the effectiveness of the scheme. | Chijie Zhuang Rong Zeng | 2014 | Communications in Computational Physics2014，15，1： | 3 |
| 7 | Recent progresses in theoretical studies and satellite observations for collisionless magnetic reconnection显示文摘As an essential mechanism in large scale fast magnetic energy releases and field reconfigurations processes in space,astrophysical, and laboratory plasmas,magnetic reconnection,particularly collisionless magnetic reconnection,has been studied for more than 65 years.Many progresses have been achieved in recent years and basic features of the process have been well understood,largely due to more and more satellite observation data available in the last decade.However,a few outstanding issues are still remained unresolved.We in the paper review the development of collisionless magnetic reconnection studies and major achievements in recent years,and also briefly discuss the open questions remained to be answered in studies of collisionless magnetic reconnection. | WANG XiaoGang XIAO ChiJie PU ZuYin WANG JiaQi | 2012 | Chinese Science Bulletin2012，57，12： | 2 |
| 8 | Electric Field Evaluation for Slender Conductors Using Collocation Boundary Element Method显示文摘Evaluation of the electric field at the surface of a conductor,which is well described by the Poisson equation,is of great importance on many occasions in power systems.This paper proposes a collocation boundary element method where the unknown surface charge density function is assumed to be either azimuth independent or dependent.Detailed formulas,including the quadrature rules and how to accelerate the computation when the target point lies far away from the integral element,are proposed.Numerical examples are shown to confirm the convergence of the method,and manifest the great advantage for the evaluation of the electric field around slender conductors. | Chijie Zhuang Yong Zhang Rong Zeng | 2019 | CSEE Journal of Power and Energy Systems2019，5，4： | 2 |
| 9 | Continuous lobe reconnectionin the mid-tail and its relationship to substorms:Cluster observations of continuous lobe reconnection in the mid-magneto tail显示文摘When the IMF turns southward, a great amount of magnetic energy is stored in the magnetotail, and the electric field across the magnetotail substantially en-hances. As long as magnetic reconnection (MR) in the mag-netotail initiates and continues, the magnetic field and plasma in the central plasma sheet are carried away to the near-Earth and down to the tail, the magnetic field and plasma in the lobe region enter the CPS and are involved in MR. We call this process “Continuous Lobe Reconnection (CLR)”. In this paper a detailed analysis of Cluster observa-tion of MR through 2001―2003 is made. Plenty of CLR events are found that led to considerable changes of tail con-figuration, appearance of BBF, as well as large-scale bubbles in which both plasma temperature and number density sub-stantially decrease. It is shown that in general CLR events last for dozens of minutes and have good correspondence to substorm initiation under the condition of continuous southward IMF. | CAO Xin PU Zuyin ZHANG Hui FU Suiyan XIAO Chijie LIU Zhenxing J.
