| 1 | 欧洲海上风电发展现状及前景显示文摘海上风能资源丰富且开发潜力巨大,海上风电开发对于应对全球气候变化问题具有重大意义。重点介绍了欧洲国家海上风电的发展现状和海上风电及输送关键技术。给出了欧洲主要的海上风电场装机容量和相关政策,并指出随着开发区域不断向深海拓展,有效降低成本至关重要。在海上风电及送出关键技术方面,介绍了大功率风力发电机、海底电缆、机组基础结构技术,以及海上风电直流汇集系统和不控整流送出方案。最后给出建议,对于海上风电场规划及并网方式选择,需要在考虑并网导则和具体技术基础上确定最终方案。 | 李翔宇 Gayan Abeynayake 姚良忠 梁军 程帆 | 2019 | 全球能源互联网2019，2，2： | 40 |
| 2 | 基于通用生成函数的海上风电集电系统可靠性与经济性评估显示文摘集电系统的可靠性与经济性对整个海上风电场的经济效益和可靠运行有重要影响。在考虑海上风电场集电系统多状态特性的基础上,对交直流集电系统的多种拓扑进行研究,提出了基于通用生成函数的集电系统可靠性评估模型和指标,该方法可以实现多状态系统的有效化简,并建立交直流集电系统经济性评估模型。算例分析以一个装机容量400 MW的大型海上风电场为例,结合拓扑结构、交直流方案和风电机组容量对集电系统可靠性与经济性进行对比。结果表明,交流集电系统的可靠性仍然高于直流集电系统,但直流集电系统一些拓扑结构有成本优势。通过灵敏度分析说明了集电电压对集电系统电缆损耗成本和可靠性的影响。 | 孙瑞娟 Gayan ABEYNAYAKE 穆清 梁军 王克文 王要强 | 2022 | 电力系统自动化2022，46，5： | 8 |
| 3 | Sociodemographic and clinical characteristics of SARS-CoV-2 infected population during the second and third epidemiological waves in Sri Lanka显示文摘Objective:To analyze data on socio-demographic and clinical characteristics of SARS-CoV-2 infected population whose samples were received from Medical Research Institute,Sri Lanka.Methods:Laboratory based retrospective study was done on patient samples which were tested positive for SARS-CoV-2 by National Reference Virology Laboratory at the Medical Research Institute,Sri Lanka,from November,2020 to November,2021.Data on sociodemographic characteristics and clinical presentation of 13126 patients were examined.Results:The mean age of the study population was(36.0±7.2)years and the majority were men(64.0%).The highest number of positive cases were found in the 21-30 years-of-age group.Two distinct peaks were noted in the incidence of SARS-CoV-2 positive individuals.In addition,42.5%of the positive samples tested positive(42.5%)were from Medical Officer of Health collection centres.Furthermore,60.6%(7951)of the infected subjects were asymptomatic whereas the remaining were symptomatic.The highest percentage of symptomatic patients were observed in the 91-100 years-of-age group while the highest asymptomatic subjects were found in the 31-40 years-of-age group.The percentage of asymptomatic children(65.3%)was significantly(P<0.05)higher than that of adults(43.4%).Conclusions:The findings of this study aid decision makers to focus on the vulnerable groups,and geographic and temporal distribution of patients in the public health strategies that aim at preventing the spread of the disease and reducinig its mortalities. | Hewa Babarandage Chathurika Harshani Ruvini Tharuka Wijewickrama Gayan Wimalarathne Chrishan Jude S Jayamaha Janaki I Abeynayake | 2023 | Asian Pacific Journal of Tropical Medicine2023，16，1： | 0 |
| 4 | Analysis and Control of MVDC Demonstration Project in the UK:ANGLE-DC显示文摘The emerging medium voltage direct current(MVDC)distribution networks are becoming more attractive due to their flexible power flow control and lower losses compared to traditional AC networks.This will significantly increase the wide uptake of renewable energy sources.The optimum utilization of the existing assets is an important aspect in grid upgrading and planning.One feasible option is to convert existing MVAC lines into MVDC operation.One of the practical demonstrations is the“ANGLE-DC”project which is also the first MVDC link in the UK.This paper highlights the innovative approach,challenges and key benefits delivered by the ANGLE-DC project. | Gayan ABEYNAYAKE James YU Andrew MOON Jun LIANG | 2020 | 供用电2020，37，10： | 0 |
