船舶智能能效管理技术发展现状及展望

Development status and prospects of ship intelligent energy efficiency management technology

受到全球变暖、环境保护以及降本增效等因素影响,各大航运企业对船舶能效管理技术的需求越来越高。本文从政策导向、市场需求以及技术驱动等3个方面分析了能效管理技术的必要性;总结了国内外现有船舶能效管理技术与产品,并从功能差异和优缺点等方面开展了现状分析;从船舶能效在线监测、能效智能评估以及能效优化控制等3个方面分析了船舶能效管理的关键技术;对船舶能效管理技术的未来发展趋势进行了展望。研究表明:监测是当前国内外船舶能效管理的基础,然后逐步发展了能效评估、航速优化、纵倾优化、故障诊断等衍生功能。在智能化程度方面,国内外的船舶能效管理仍以离线分析为主,以动态、在线、自主化为特征的智能评估和优化比较缺乏。本文可为船舶动力系统低碳化、智能化研究与发展提供指导。

Affected by global warming,environmental protection,cost reduction,and efficiency improvements,the major shipping companies are increasingly demanding energy efficiency management technology.The necessity of an energy efficiency management technology is analyzed in this paper from three aspects:policy orientation,market demand,and technology drive.The existing ship energy efficiency management technology and products at home and abroad are summarized,and the status quo is analyzed from the perspectives of functional differences,advantages,and disadvantages.The key technologies of ship energy efficiency management are analyzed,including on-line monitoring,intelligent evaluation,and optimization control of energy efficiency.Finally,future development trends in ship energy efficiency management technology are forecasted.Analysis shows that energy efficiency data monitoring is the basis of current energy efficiency research at home and abroad,and functions,such as energy efficiency evaluation,speed optimization,trim optimization,and fault diagnosis,are gradually developed.In terms of intelligence,ship energy efficiency management at home and abroad is mainly analyzed offline,while intelligent evaluation and optimization characterized by dynamics,on-line,and automation are relatively scarce.This study can provide guidance for the research and development of low carbonization and intelligent ship power systems.
