摘　　要：针对扩展黑启动方案的恢复相对效率研究,提出了一种基于超效率数据包络分析模型的评估方法。首先,介绍了数据包络分析模型基本理论;然后,根据扩展黑启动同时启动多台机组形成规模更大系统的具体实际,构建了涵盖恢复时间、机组恢复效果、网络结构性能等反映恢复过程中多要素的评估指标,在此基础上以超效率数据包络分析模型评估其相对效率。以实际电网的扩展黑启动方案作为分析算例,计算结果验证了所提出的基于超效率数据包络分析模型评估方法能够对扩展黑启动方案恢复相对效率做出客观有效的评价。An assessment method based on the SE-DEA（Super Efficiency Data Envelopment Analysis） model is proposed to investigate the relative efficiency of extended black-start restoration plan. The basic theory of DEA model is introduced and multiple assessment indexes are constructed according to the simultaneous restart of multiple units in extended black-start to reflect the multiple factors of restoration process,such as restoration time,unit restoration,network structure and so on,based on which,the SE-DEA model is adopted to evaluate its relative efficiency. As an example,an actual extended black-start restoration plan is evaluated by the proposed method and results demonstrate that it evaluates the relative efficiency of extended black-start restoration plan objectively and effectively.
