天津市6—9月气温与供电量的关系分析

为探讨不同气温指标对城市夏季供电量的影响,对天津市区2002—2004年6—9月逐日供电量、日最大负荷、日最小负荷与02、08、14时和20时、日平均、日最高和日最低气温共7种气温指标的相关性进行综合统计分析，并对相关系数作假设检验。结果表明：平均气温与夏季逐日供电量、日最大负荷相关性最好，02时气温与最小负荷的相关性最高。日平均气温和02时气温是影响城市夏季供电量的主要气象要素。

Relationship between electrical energy supply and air temperature from June to September in Tianjin,China

In order to discuss the influence of different air temperature indices on summer electrical energy supply in Tianjin, the relationships of the daily electrical energy supply, daily peak load, daily minimal load with seven air temperature indices (two o’clock, eight o’clock, fourteen o’clock, twenty o’clock, daily average, daily maximum and daily minimum air temperature) were analyzed by statistical methods, and the hypothesis test of the correlation coefficient had been done. The results indicate that the correlations of the average air temperature with daily electrical energy supply and daily peak load are significant, and the correlation between two o’clock air temperature and the daily minimal load is significant. The daily average temperature and two o’clock air temperature are the main meteorological elements influencing the urban electrical energy supply in summer.
