摘要
利用华中电网4省1986~1994年逐月全社会用电量(e1)、居民生活用电量(e2)及同期气候资料研究表明:1)4省气候变化趋势一致即年变化小但季节变化大;2)e1,e2均呈线性增加趋势,冬夏增加最快,e2的相对增长比e1的相对增长快近1倍;3)河南省各季两项气象(影响)用电量与气温均为正相关,与雨量均为负相关,其余3省与气温大多为负相关;4)气温对气象(影响)用电量的影响大于雨量的影响;最后分析了两项气象(影响)用电量与气温的第一对典型变量权重系数的分布特征.
It is revealed that: 1) four provinces in Central China have had the same climatic changing tendency since 1986, such as warmer winter,cooler summer and less rainfall in autumn,more rainfall in other seasons; 2) the total or house power comsumption( e 1,e 2 ) has linear increasing tendency, the relative increasing speed of e 2 is two times of that of e 1 ; 3) electricity consumption ( Y ) affected by weather in Henan is positively related with temperature( T ) and negatively related with rainfall( R ), Y in Hubei,Hunan,Jiangxi mainly have negative relations with T ; 4) T has more important influence on Y than R does.Finally it is analysed that the distibution properties of weighted coefficients of first pair of canonical variables between Y and T .
