船舶能耗模型构建及清洁能源适用性分析

Ship energy consumption model construction and clean energy applicability analysis

清洁能源应用是航运业实现减碳目标的主要措施,清洁能源动力船舶的运行特点与通航环境的关联性比柴油动力船更大,准确计算船舶能耗和排放是清洁能源适用性分析的前提。采用Matlab/Simulink平台,构建基于通航环境和实际营运策略的能耗计算模型。以长江7 500吨级干散货船为例,综合分析船舶采用不同能源动力形式的计算结果,推荐出适配的清洁能源应用方案。结果表明:当前阶段,LNG是适用的清洁能源,混合动力、柴油-LNG双燃料机械动力是适配的动力形式。

Clean energy application is the main measure to achieve the carbon reduction target in shipping industry. The operating characteristics of clean energy powered ships are more related to the navigational environment than diesel powered ships, and accurate calculation of energy consumption and emission of ships is the prerequisite for clean energy applicability analysis. Matlab/Simulink platform is used to construct an energy consumption calculation model based on the navigable environment and actual operation strategy. Taking the Yangtze River 7 500-ton dry bulk carrier as an example, the calculation results of different energy power forms are analyzed comprehensively, and the suitable clean energy application scheme is recommended. The results show that LNG is the applicable clean energy source at the current stage, and hybrid power and diesel-LNG dual-fuel mechanical power are the suitable power forms.
