In order to promote construction of offshore wind farms in far-reaching sea areas and rational use of ma-rine resources,a decision-making model based on fuzzy logic is proposed for site selection of offshore wind farms in far-reaching sea areas.First,influencing factors are identified from existing studies,based on which a three-layer decision-making framework is established.Second,input and output variables are fuzzified,and four fuzzy logic boxes are estab-lished by using decision attributes,which are wind resources,natural environment,traffic environment,and fan condi-tions.Then associated reasoning rules are also developed.Third,weights of decision attributes are derived by using lin-guistic variables for final decision-making.Finally,take site selection of offshore wind farms in Shanghai as a case study, its scheme is determined by this method.%为了促进我国深远海海域海上风电场建设,实现海上资源的合理使用.研究了基于模糊逻辑的深远海海域海上风电场选址方法.根据现有研究成果,识别了深远海风电场选址的影响因素,建立了深远海风电场选址的3层决策框架.利用模糊推理对输入和输出变量进行模糊化,以风能资源、自然环境、交通环境和风机条件建立了4个模糊推理机,并构建了其模糊推理规则.利用模糊语言变量确定了各决策准则的权重,从而实现深远海风电场选址的决策.以上海市深远海海域海上风电场选址为实例,确定了其选址方案.
