关于负荷分析和变压器的选择

About Load Analysis and Transformer Selection

在对城市配电进行方案设计的时候,确认其实际的负荷状况是方案设计中最基本也是最重要的部分,因为在城区其人员比较密集,用电量规划工作复杂,需要收集供电基础资料,调查有关社会经济发展的历史数据,认真深入分析电网现状,结合城市总体发展规划、土地资源和环保规划等,对当地城市电网的特点及用电特点进行合理的负荷分析。而在电力系统中,变压器是其不可缺少的部分,按照科学的方法选择合适的变压器型号,既能保证电力系统的正常运行,也能减少投入的成本,还能起到保护环境的作用。本文主要研究负荷分析和变压器的选择。

Load analysis is the basis for planning of urban electric power and the important content,is to determine a reasonable basis of city power grid scale and layout,work planning of urban electric power complex,need to supply basic data collection,investigation and historical data about the social and economic development,analysis of the current situation of serious deep into the power grid,combined with the overall planning of urban development,land resources and environmental protection planning,characteristics of the local city power grid and analyzes the reasonable electricity load characteristics,the transformer is used in power system are indispensable and widely used equipment,the selection of the transformer is correct and reasonable,is the power system economic,safe and reliable operation of the guarantee,and also have important significance in saving energy and reducing consumption.
