基于AHP-CRITIC的海上风电升压站冷却系统方案设计与评估

Design and evaluation of cooling systems in the offshore wind power booster station based on AHP-CRITIC

针对某海上风电升压站二层和三层的设备舱,提供了多联机冷却系统、以海水为冷源的风机盘管冷却系统和以海水为冷源的辐射供冷系统3种冷却系统方案,并进行设计分析.基于层次分析法(analytic hierarchy process,AHP)和CRITIC(criteria importance through inter-criteria correlation)赋权法构建评价体系,从经济、施工和节能3个方面对3种冷却系统方案进行评估,并且对设备成本、所需空间大小和管路设备安装难度等重要因素分配权重.结果表明:多联机冷却系统得分为74.1,以海水为冷源的风机盘管冷却系统得分为78.3,以海水为冷源的辐射供冷系统得分为81.4,以海水为冷源的辐射供冷系统评价结果最优.将AHP和CRITIC赋权法相结合并应用于海上风电升压站冷却系统,有利于其他冷却系统的实际应用与选择.

In this study,three types of cooling systems-varied refrigerant volume(VRV)cooling system,fan coil cooling system with seawater as a cold source,and radiant cooling system with seawater as a cold source-were designed for the electronic equipment cabin of an offshore wind power booster station.We developed an evaluation system to study these three cooling systems from three aspects,namely economy,installation,and energy savings.We assigned the weights of important factors,such as equipment cost,manual installation cost,and operation and maintenance cost,in the analytic hierarchy process-criteria importance through inter-criteria correlation(AHP-CRITIC).Scores of 74.1,78.3,and 81.4 were obtained for the VRV cooling system,fan coil cooling system with seawater as a cold source,and radiant cooling system with seawater as a cold source,respectively.These findings indicate that the AHP-CRITIC method can be successfully applied to the selection of cooling systems for offshore wind power booster stations.The proposed evaluation method is expected to contribute to the practical application and selection of other cooling systems.
