摘　　要：建立基于试验数据的空调负荷模型,在对空调负荷无功-电压特性分析的基础上,运用静态电压稳定性分析方法,研究不同负荷组成和负荷增长方式下空调负荷对城市电网电压稳定性的影响。通过对华东地区栽城市实际电网的计算分析,说明空调负荷会对城市电网的电压稳定性产生不利影响,无论空调负荷是总数量的增加还是占总负荷比例的增加,都会导致电网的电压稳定性降低,对于负荷裕度较小以及无功功率缺乏的电网来说尤其需要采取措施加以防范。An air conditioner load model based on test data is presented. On the basis of reactive power-voltage characteristics analysis of air conditioner load, this paper studies on the effect of air conditioner load on voltage stability of urban power system by changing load components and load increasing modes. Static voltage stability analysis method is adopted. The computational analysis of a real urban power system in East China shows that air conditioner load has a bad impact on voltage stability of an urban power system. The increasing either in total load or in the proportion of the total load will both decrease the voltage stability. So measures should be taken to prevent voltage instability, especially for the system which has small loading margin and poor reactive power.
