海上风电用±550 kV直流GIS过电压与绝缘配合研究 [PDF]
全球能源互联网海上风电经柔性直流送出已成为风电消纳的重要途径。直流气体绝缘开关设备（gas insulated switchgear，GIS）用于海上风电换流平台，可以降低整体海上换流站平台体积及设备造价，降低了海上设备的运维成本。围绕海上风电用±550 kV直流GIS的过电压与绝缘配合进行研究，首先确定柔直系统的结构与参数、控制保护策略和避雷器配置方案，进而通过仿真获得最大过电压水平，对于不同运行方式下故障极与非故障极的直流极线过电压进行分析，最后明确±550 kV直流GIS中避雷器参数与±550 ...

Change in cyclone disaster vulnerability and response in coastal Bangladesh
Disasters, Volume 48, Issue 2, April 2024.The number of deaths owing to tropical cyclones in Bangladesh has significantly reduced. Category 4 Cyclone Gorky in 1991 and Sidr in 2007 caused 147,000 and 4,500 deaths respectively, whereas Category 1 Cyclone Mora in 2017 resulted in six. Face‐to‐face interviews with 362 residents, participant observation, and focus‐group discussions answer a ...

全球能源互联网, 2019 海上风能资源的有效测量及合理评估是项目开发的基础。目前，海上风能资源测量及评估方面的研究及规范较少，且其测量环境与陆地差异较大，导致测量和评估有一定难度。适宜的测量高度以及合理的支臂朝向设置是获得有效测量数据的关键。海上测风塔测量环境应与风电场相似，需结合地形具体分析岛礁测风塔的测量高度。为便于塔影效应分析，建议在海上测风塔垂直主导风向的支臂安装两套风速仪。塔影分析与50年一遇最大风速计算是海上风能资源评估的重要问题。考虑到塔体结构差异，海上测风塔塔影效应分析方法与陆地测风塔有所不同 ...

Exploration for effects of acoustic stimulus on movement behavior and HSP70 expression of two kinds of marine crustaceans [PDF]
, 2016 水下噪声会潜在的引起海洋生物紧张，分散和掩蔽这些海洋生物重要的声信号，进而对海洋生物的行为和生存造成影响。近几十年来，随着人类社会的不断发展，人们将发展目光投向了占有全球71%面积的海洋。伴随海洋事业的快速发展，海洋工程噪声对海洋生物的影响引起了人们的极大关注。虽然目前已有不少研究成果评估了水下工程噪声对海洋生物的影响，这些噪声包括轮船、打桩、地震勘探以及风电场等水下噪声，表明海洋工程等人为噪声对鱼类以及海洋哺乳动物都将造成了不同程度的影响和伤害。但是 ...
