| 摘要: |
| 目前海上油气工程微能系统的能源利用效率缺乏有效评估手段，无法有效对比各运行方式下的能源利用效率，使得难以合理选择运行方式。为了优化海上油气工程微能系统的运行方式，根据系统的物质能量流结构，运用能源集线器矩阵建模方法，建立了海上油气工程微能系统的标准化模型；提出了海上油气工程微能系统的综合能效评估指标，并利用信息熵计算指标的权重分布情况；提出了综合考虑能效水平与经济性的海上油气工程微能系统优化模型，并对比了优化前后的能效指标值和综合能效评估结果。计算结果表明，优化运行方案能显著提高系统的能源利用效率，使综合能效评估结果最优。 |

| Abstract: |
| At present, there is no effective evaluation method of energy utilization efficiency for micro integrated energy system in offshore oil and gas engineering, which cannot effectively compare the energy utilization efficiency under various operation modes, making it difficult to choose the reasonable operation mode. In order to optimize the operation mode of the micro integrated energy system in offshore oil and gas engineering, according to the material energy flow structure of system, the energy hub matrix modeling method is used to establish the standardized model of the micro integrated energy system in offshore oil and gas engineering. Then, the comprehensive energy efficiency evaluation index of the micro integrated energy system in offshore oil and gas engineering is proposed, and the information entropy is used to calculate the weight distribution of each index. Furthermore, the optimization model for micro integrated energy system in offshore oil and gas engineering that considers energy efficiency level and economy comprehensively is proposed, and the energy efficiency index values and the comprehensive energy efficiency evaluation results before and after optimization are compared. The calculative results show that the optimizing operation scheme can significantly improve the energy utilization efficiency of system, so that achieving the optimum comprehensive energy efficiency evaluation results. |
