摘要
根据配电网运行数据的实际采集情况,建立了基于潮流计算和关联度计算的两层节能指标模型;通过电网节能指标进行配电网能效分析,结合节能改造手段建立节能潜力分析架构;提出了采用前推回代潮流计算法和灰色关联预测法相结合的混合算法求解模型;并给出了适用于配网节能改造的节能潜力分析流程。最后以某供电公司10 k V典型线路和局域配网为例,验证了上述节能潜力分析模型及算法的有效性。
Based on the operation data collection of distribution netw ork,tw o layered index models for flow calculation and relational prediction w ere established. With energy saving indexes,the energy efficiency of distribution netw ork w as analyzed; the saving potential analysis architecture w as developed based on energy saving reconstruction method. A hybrid algorithm using forw ard and backw ard substitution flow calculation and gray relational prediction method w as proposed to solve the above model. M oreover,the analysis processes of energy saving potential w ere proposed for the energy saving reconstruction of distribution netw ork. Finally,taking a typical 10 k V line and a small distribution netw ork in a pow er supply company as examples,the effectiveness of the energy saving potential analysis model and its algorithms w ere verified.
