摘要：In the project of "Substituting Electricity for Coal" in northern rural areas, more and more air source heat pump units are being used for home heating. When the large-scale units are connected to rural distribution networks, the power quality problems should be considered because of the voltage sag and the current harmonics caused by these units. The characteristics of the air source heat pump units are compared with those of other domestic electric heating radiators. The efficiency indices, the operating circle and the types of air source heat pumps are introduced. The starting and operational characteristics of different air source heat pump units are given and compared. The power quality problems, the voltage sag and current harmonics are analyzed and discussed based on the parameters and the actual measurement data of the units in the rural distribution networks. Some solutions are presented for the problems caused by the units.
