【正文】 據(jù)分析結(jié)果確定避雷器的最佳安裝點(diǎn)。根據(jù)基于EMTP的牽引變電所仿真模型，針對(duì)不同避雷器設(shè)置方案對(duì)雷電侵入波防護(hù)效果的模擬和分析結(jié)果，選擇的最佳避雷器安裝方案為：在變壓器和互感器入口處均設(shè)置避雷器。As the power supply of electrified railway, traction substation is an important part of the railway power supply system, which directly affects the safety of railway of the large amount of centralized equipment in traction substation, it is easy to cause equipment failure by lightning, and then affect the safety and reliability of railway power supply , the a The Electromagnetic Transients Program e equipment in traction substation from lightning strikes and to ensure the safety and reliability of tractive power supply design uses EMTP(The Electromagnetic Transients Program)application software, take the railway traction substation as an example, the establishment of 220kV traction substation simulation model, electromagnetic transient simulation software, to analysis lightning invasion wave of 220 kV traction substation on the equipment of lightning struck point, the surge groundresistance and the place arrester ridded are pared, to ensure the right location of to the traction substation model, which based on the EMTP, the effect of lightning overvoltage by different installation scheme about arrester is simulated and to the simulation results, it is adopted as lightning protection design scheme that arresters should be located near transformer and mutual inductor.第五篇：摘要翻譯AsiaPacific Economic Cooperation(APEC), a single official economic forum at first, now has developed into a economic cooperation organization that plays an important role in the the continually expanding of its scale , its original several members now bee importance for the world has been greatly improved, and its influence for international regional economic cooperation also has rapidly paper makes some introduction to APEC, but the emphasis of it is to study APEC’s influence for international trade and the relevant countermeasures 2014, APEC is held again in has joined APEC for 25 years, as the opening of APEC meeting, Chinese actual economic change in this 25 years once again bees the focus of attention for this issue, this paper talks about Chinese development process in this 25 years, and the concerned focus and establishment of countermeasures in 2014 APEC meeting, so that the impact that China’s entry into APEC makes for Chinese trade can be grasped as a the development situation and existing problems of APEC in recent years, this paper offers some relevant according to the meeting content and development situation, this paper also analyzes APEC’s future planning.
