摘　　要：空调降温负荷的比例和影响日益增大,必须予以重视。首先分析了空调降温负荷与气候的关系,建立了河南电网夏季日最高负荷与气候指数的回归模型,获得空调降温负荷比例的估计公式。然后通过综合仿真程序,分析空调降温负荷在电压回复后的重新启动特性对电压稳定的影响,结果表明这对电压恢复具有严重的恶化作用。Air conditioner load is increasing and should be paid more attention. A model is set up for predicting the air conditioner load varying with the temperature in Henan Power Gird. The influence of air conditioner load, especially the re-staring process, on power system voltage stability is studied. The results show that air conditioner load is bad to power system voltage stability. This paper is supported by Natinal Natural Science Foundation of China（ No. 5059412）.
