A Relationship between Daily Electric Loads and Meteorological Elements in Central China

The meteorological electric loads, which follow weather conditions, is deduced from the loads of electric network over four provinces in central China according to data from February 1997 to May 2000. The relations between meteorological electric loads and weather data are analysed,and the features and their variation rules of relations between meteorological electric loads and air temperture over four provinces in central China are discussed,respectively. The investigation shows that the correlativity bewteen them is in evidence. The correlative coefficient is positive when average temperture is more than 20℃ and negative when it is below 20℃. And the meteorological electric loads vary rapidly with air temperture when it is among 25-28℃.
