Space station thermal control surfaces. Volume 1: Interim report [PDF]

open access: yes
The U.S. space program goals for long-duration manned missions place particular demands on thermal-control systems. The objective of this program is to develop plans which are based on the present thermal-control technology, and which will keep pace with

Novel Techniques to Reduce Transformer Inrush Current Using EMTP Software

open access: yesمهندسی مخابرات جنوب
Transformer inrush current is a high-amplitude, non-sinusoidal transient that occurs during initial energization, leading to voltage dips, power quality degradation, and relay misoperations.

超高压变电站雷电过电压现场实测与仿真计算

open access: yesDianci bileiqi, 2008
简述了电力系统过电压问题的研究方法:TNA具有直观性,实测具有真实性,仿真计算具有灵活性。为研究某超高压变电站雷电过电压与绝缘配合问题,用低压冲击波进行了时间比例尺、阻抗比例尺均为1的现场试验,且用ATP-EMTP仿真计算了设备上的雷电侵入波过电压。试验结果表明,一线一变、一线两变两种运行方式下,降压实测与ATP-EMTP仿真计算结果基本一致,说明将实测与计算结合起来是一种分析此类问题很好的方法。
