摘　　要：随着经济的发展,空调负荷在负荷成分中已占有相当大的比重,并且对电网电压稳定有着不可忽略的负面影响。为了分析夏季含有大量空调区域的负荷特性,给出了含有空调的综合电力负荷建模的方法。对于其中的空调负荷比例这一重要参数,提出了一种基于地理分区,按照负荷节点类型计算空调负荷比例的实用化方法。通过单台空调实验,分别用纯电动机模型和电动机综合负荷模型辨识空调负荷参数,拟合其动态响应。结果表明,空调负荷在正常干扰时,不能够采用纯电动机模型描述,而应该采用综合电动机负荷模型描述。In order to analyze the load characteristics in areas where a large amount of air conditioners is included in summer, a method for load modeling including air conditioners is proposed. While air conditioner ratio is a vitally important parameter, a computation method is used to obtain the ratio for each type of load in different districts. To confirm the load model which is adapted to the air conditioner load, the parameters with real measured data using synthetic induction motor model and pure induction motor model are identified, and their dynamic responses are compared respectively. The results show that under normal disturbances, the synthetic induction motor model is preferred to pure induction motor model as air conditioner load model.
