| 2 | 电力系统实时数字仿真器RTDS显示文摘电力系统实时数字仿真器RTDS(RealTimeDigitalSimulators)是实时全数字电磁暂态电力系统模拟装置 ,采用与EMTP仿真程序相同的算法 ,但由于其具有很强的硬件计算能力 ,进行系统研究时速度要快得多。另外 ,RTDS仿真系统的频率特性包括了一个很大的频率范围 (从直流到 4kHz) ,在此频率范围内 ,RTDS仿真系统是全面分析电力系统各种问题的理想工具。RTDS仿真系统可以用于电力系统分析研究、测试保护系统。 | 叶林 杨仁刚 杨明皓 Rick Kuffel 林华谘 | 2004 | 电工技术杂志2004,26,7: | 15 |
| 3 | Key Techniques in Real Time Digital Simulation for Closed-loop Testing of HVDC Systems显示文摘This paper introduces several key techniques in realtime digital simulation for closed-loop testing of high voltage direct current(HVDC)systems,including line commutated converter(LCC)HVDC valve group models,modular multilevel converter(MMC)HVDC models,phase domain frequency dependent transmission line models,and switchable filter models.Various issues such as background,algorithms,implementations,applications,and validation of these models are introduced.These techniques represent the most advanced technology in modelling HVDC systems on a real time simulator.The models have been implemented on the RTDS Simulator,a comprehensive real time power system digital simulation tool. | Yi Zhang Hui Ding Rick Kuffel | 2017 | CSEE Journal of Power and Energy Systems2017,3,2: | 7 |
| 4 | 基于介质阻挡大气压空气均匀放电的聚丙稀薄等离子体表面处理(英文)显示文摘The homogeneous dielectric barrier discharge(DBD) in atmospheric air is most favorable for polymer surface modification due to the low cost of operation and the ability of ambient on-line continuous uniform processing.In this paper,polypropylene(PP) films are treated using a homogeneous DBD plasma in atmospheric air.The surface properties of PP films are studied using contact angle and surface energy measurement,scanning electron microscopy (SEM) and Fourier transformed infrared spectroscopy(FTIR),and the aging effect after treatment when the treated materials are exposed to open air is also studied,with the modification mechanism being discussed.It is demonstrated that non-thermal plasmas generated by homogeneous DBD in atmospheric air is an effective way to enhance the surface properties of PP films.After the plasma treatment,the surface of PP film is etched,and oxygen-containing polar groups are introduced into the surface.These two processes can induce a remarkable decrease in water contact angle and a remarkable increase in surface energy,and the surface properties of PP films are improved accordingly. | 方志 蔡玲玲 雷枭 邱毓昌 Kuffel Edmund | 2011 | 高电压技术2011,37,11: | 6 |
