多绕组电机模型的Matlab／SimPowerSystem实现

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。

Realization of multi-winding synchronous machine model by Matlab/SimPowerSystem

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.
