ABSTRACT Bangladesh's goal of achieving high‐income status by 2041 requires dependable, low‐emission, and affordable energy. With near‐universal grid coverage and increasing demand, nuclear energy is a strategic asset for long‐term baseload supply. However, the existing financing model, typified by the country's most expensive $12.65 billion Rooppur ...

文中对国家标准《GB 1984—2014高压交流断路器》及《GB/T 4473—2008高压交流断路器的合成试验》、国际短路试验联盟STL导则中关于三相全电压关合的内容进行了解读,通过对直接试验回路中三相全电压关合过程进行模拟明确关合过程中断路器两端电压和电流波形的变化,对两种合成关合试验回路进行模拟分析并比较,提出了一种便于实现且等价性较好的三相全电压关合试验回路。结果表明该回路与目前标准推荐回路相比,实现难度较小,笔者推荐实验室可选择该试验回路。

交流滤波器回路是特高压换流变电站的重要设备回路,但其特殊的结构特征导致其在强震作用下易发生破坏。为研究交流滤波器回路的地震易损性,文中通过有限元数值仿真计算的方法,对某800 kV换流站交流滤波器回路进行了数值建模,基于数值模型进行了模态分析和地震响应时程计算,并进行了回路地震易损性分析。结果表明:交流滤波器回路中的高压电容器和电阻器支柱绝缘子根部应力水平较高,有破坏风险;软母线的轴拉力远低于其计算拉断力;考虑母线耦联作用后,高压电容器和电阻器等应力较高的设备地震响应有所降低;PGA高于0.4g时 ...

Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

[[abstract]]在這個時代,人與人之間的交流必然少不了網路,從媽媽問兒子晚上要吃什麼,到公司員工利用網路繳交工作文件都是需要網路的。而網路不只是幫助人們更方便的互相交流,也促成了機器與機器之間的資訊傳遞,例如家裡有個網路攝影機以及一個智慧音箱,只要拿起手機打開APP按下出門,網路攝影機便可開啟偵測模式,只要有任何動靜,就會將畫面與聲音錄下,並利用家中的WiFi將影音檔上傳至雲端,而在家裡時如果突然想聽某某歌手的音樂,只要呼喚智能音箱,就能立即撥放,這一切方便的功能 ...

断路器机构自带完善的控制回路,与断路器保护操作箱功能上存在重复、冲突,如果配合不好,会影响断路器以及电网安全稳定运行。笔者对机构操作回路和保护操作箱在防跳回路、跳合闸压力闭锁以及非全相保护回路的特点进行了分析总结,对改进两者在这些回路的配合方面进行了研究,提出在机构箱防跳回路中串联"就地/远方"切换把手ZK的接点;压力低禁止跳闸、禁止合闸、禁止操作等功能由断路器本体实现,压力低闭锁重合闸回路只选用第一路操作电源;以及采用断路器本体非全相保护,基于电气量的非全相保护作为补充之用 ...

Passing on the red genes: Communism nostalgia in online fictions and ideological governance in China
Abstract How does communism as an ideology fare in the post‐reform digital age China? What are the implications for China's ideological governance? Through online ethnographic work and text analysis, this paper identifies and analyzes how communism as an ideation and a practice is (re)memorized, (re)presented, and (re)interpreted in popular online ...
