摘要
变频空调的应用越来越广泛,其在电力负荷中所占比重越来越高。建立准确的变频空调负荷模型对于提高电力系统仿真的准确度具有重要意义。本文在详细分析变频空调运行原理和各组成元件特性的基础上,提出了变频空调的功率-温差模型,分别建立了变频空调的静特性模型和动特性负荷模型。通过实验室实测变频空调的运行特性,将变频空调负荷模型的响应与实测曲线进行了对比。结果表明,本文所提出的变频空调静特性和动特性模型能够准确地描述变频空调的负荷特性,具有较高的准确度。
With the progress of power electronics technology and the continuous improvement of people’s living standards,the application of frequency conversion air conditioner is more and more widely,and its proportion in the power load is higher and higher.It is important to establish an accurate load model of variable frequency air conditioning system for improving the accuracy of power system simulation.In this paper,based on the detailed analysis of the operation principle and the characteristics of each component of the variable frequency air conditioner,the temperature-power model of the variable frequency air conditioner is put forward,and the static characteristic model and dynamic characteristic load model of the variable frequency air conditioner are established respectively.The operating characteristics of inverter air conditioners were measured in the laboratory,and the response of the inverter air conditioner load model was compared with the measured curve.The results show that the static and dynamic characteristic models presented in this paper can accurately describe the load characteristics of variable frequency air conditioning with high accuracy.
