摘要
为满足重量、体积、谐波等方面的特殊要求,独立电力系统常采用交直流多绕组发电机、多相电动机等特种电机。这使得系统的仿真分析与陆用广域电力系统相比差异较大。基于MATLAB/SimPowerSystem,本文提出了一种多绕组发电机的三相发电机等值模型。通过在普通三相发电机基础上增加磁耦合,该模型能够实现多绕组发电机的模拟。与其他实现方法相比,所提出的方法能够充分利用现有仿真算法,可方便地实现独立电力系统的时域仿真。
Special type electric machines are widely used in isolated power systems for the particular requirements, caused by such restrictions as weight, volume and harmonics. This fact leads to a large difference between the simulation of isolated power systems and the terrestrial ones appeared. This paper proposes a novel method for realizing the model of multi-winding synchronous generator based on the three-phase generator in MATLAB/ SimPowerSystem. This method utilizes the characteristics of magnetism coupling and can conveniently solve the simulation problem in a class of special type electric machines. Comparing with other realization methods, this method can sufficiently use the existing simulation methods, and makes the simulation work become more efficient and easy-operating.
