中文摘要:

随着电力电子技术的发展,变频调速技术的使用也越来越广泛。因此,对于变频电机的建模与分析也得到了越来越多的学者的关注。另外,由于分布式电源的接入,频率对电网产生的影响较大,因此考虑负荷的频率特性也具有重要的意义。本文采用两种方法对考虑频率特性的变频电机模型进行建模。一是变频调速矢量控制法、二是动态相量法。最后与不考虑频率特性的异步电动机进行比较分析,找出更符合实际的负荷模型。

英文摘要:

With the development of power electronic technology, the use of variable frequency technology has become more and more widely. Therefore, more scholars have been concerned about the modeling and analysis of variable frequency. In addition, due to the access of distributed power, frequency has a great impact on the power grid, so, it is important to consider the frequency characteristics of the load. In this paper, two methods are used to model the frequency conversion motor model. One is the variable frequency speed regulation vector control method, the other is dynamic phasor method. And finally, compared with the motor that not consider the frequency characteristics to find the load model which fit for the truth.
