中文摘要: 从华中电网4省1997年2月至2000年5月逐日的电力负荷资料中分离出随气象因子变化的气象负荷,分析了气象负荷和同期的气象资料的相关关系,重点研究了气象负荷随气温变化的规律,探讨了华中各省气象负荷与气温关系的异同。研究表明华中电网日负荷与日平均气温的相关关系明显,在日平均气温大于20℃时相关系数为正,小于2 0℃时为负,在气温为25~28℃时负荷对气温的变化最敏感。
Abstract: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℃.
