合理选择特高压（UHV）交直流输电方式是未来特高压电网建设规划中至关重要的一个环节。为此，以特高压交直流输电方式优选作为研究对象，提出了一种基于模糊优选的特高压交直流输电方式综合优选方法。首先建立了一套包含电网结构、电网安全性、经济性、环境影响等多影响因素的特高压交直流输电方式评价指标体系，其次引入了改进层次分析法（AHP）和标准差及平均差方法进行组合权重的计算，最后通过模糊优选方法计算不同备选方案的隶属度，实现输电方式的优选决策。将该方法应用于湖北电网“十二五”新增特高压输电方式的优选，结果表明特高压交流输电方式的综合隶属度为1，而直流方式的最佳相对隶属度为0．588，交流输电方式优于直流输电方式。

Reasonable selection of UHV AC/DC transmission modes is the foundation of UHV network planning. Aiming at the optimal selection of UHV AC/DC transmission modes, a comprehensive evaluation method of UHV AC/DC transmission modes based on fuzzy optimization techniques is presented. Firstly, an index system, including the grid structure, the system security, the operating economy, and the environmental factors, is established to evaluate the feasibility of the transmission modes. Then, the combination weights are calculated by the improved analytic hierarchy process (AHP) and the mean and standard deviation methods. Finally, the fuzzy optimization techniques are used to evaluate the membership grades of different alternatives. The application of the proposed method is applied in transmission mode selection of the 12th five-year plan of Hubei Power grid, and the result shows that the membership grade is 1 and 0. 558 for UHV AC transmission mode and UHV DC transmission mode respectively, showing that the UHV AC mode is better than the UHV DC mode in this case.
