陕西电网用电量与气象因子的关系

A relationship between meteorological electric quantity and meteorological elements in Shaanxi Province

从陕西电网日用电量资料中分离出随气象因子变化的气象电量，分析了气象电量与同期气象资料的相关关系，重点研究了气象电量随气温变化的规律。结果表明：陕西电网用电量与平均气温的相关关系显著，在5～9月(平均气温大于或等于18℃)为正相关，10月到次年4月(平均气温小于18℃)为负相关，在日平均气温为28～31℃时电量对气温的变化最敏感。

The meteorological electric quantity, which follow weather conditions, is deduced from the quantity of electric network over Shaanxi according to data from Jan. 1998 to Dec. 2001. The relations between meteorological electric quantity and weather data are analyzed, and the features and their variation rules of relations. The investigation shows that the correlativity between them is in evidence. The correlative coefficient is positive from May to September, and negative from Oct. to Apr.; and the meteorological electric quantity very rapidly with air temperature when it is among 28～31℃.
