摘要
利用 1996～ 2 0 0 0年的南京市供电负荷及气象数据 ,基于SAS系统和EXCEL软件 ,采取数学统计方法进行相关规律的研究 ,以便对电网安全经济运行和规划提供有效的服务。主要以夏冬 2个典型季节为对象 ,从 3个方面分析了导致负荷快速增长的气温因素与电力负荷之间的关系。分析结果表明 :气温对季节性电力负荷的影响越来越显著 ,与最高负荷的增长对应有一个最相关温度因子 ,它们的变化趋势基本一致 。
The abundant data of weather and load from 1996 to 2000 is studied by using mathematical statistics methods.It is based on a plentiful market investigation and research for the safe and economical operating and planning of power network.It is carried out on SAS and with MS EXCEL.With summer and winter as the typical seasons and from three aspects,the relationships between air temperature and electric loads are analyzed,which leads to the rapid increasing of electric loads.It shows that the air temperature influences seasonal electric loads remarkably. The maximum load has the closest relation with temperature factor and their variations are roughly coincident.The sensitivity of load vs.temperature is various in different temperature ranges.The further study on it is necessary to deeply understand the characteristics of electric loads.
