基于智能搜索的配电变压器综合效益模型

摘要

为了提高配电变压器的综合经济性，研发了一种基于智能搜索的配电变压器综合效益模型；携带电能质量分析仪FLUKE435对南方电网区域内某工矿企业进行24小时不间断监测，并通过较精确的计算方法将测得数据代入模型。在节能运行方式下，模型计及变压器负载系数、容量费、空载损耗、负载损耗收期最小的配变容量；并与经典节能改造方案进行对比，证明基于智能搜索模型的新方案能够兼顾企业的经济效益与社会的节能效益，实现企业和社会的双赢。%To improve comprehensive economy of distribution transformers,this paper develops a comprehensive benefit model for distribution transformers based on intelligent search.Power quality analyzer FLUKE435 is used for uninterrupted monitoring of an industrial/mining enterprise in the area of China Southern Power Grid on the 24-hour base,and measured data are taken into the model in a quite precious calculation method.In the energy-saving operational mode,the model completes computation of the capacity of distribution and transformation under consideration of transformer load factor,capacity fee,zero-load loss,load loss and optimal return on investment.A comparison with classical energy-saving modification schemes verifies that this novel scheme based on intelligent search can balance enterprise's economic benefit and social energy-saving effect to create win-win situation between the enterprise and the society.
