基于MATLAB电气模块的磁路饱和的异步电机的性能仿真

Simulation of the Asynchronous Machine Considered of the Majnetic Circuit Saturation Effects Based on Library of Models in MATLAB

鉴于利用MATLAB电气模块直接搭建对电机系统仿真的便捷性,其SIMULINK仿真环境在电力系统运行中得到了广泛的应用。但MATLAB本身提供的异步电机模型没有考虑激磁电抗的非线性,这就使得在对异步电机作为风力发电机的电压曲线进行仿真时造成误差。为此,提出了1种利用SIMULINK中的电气模块对异步电机的这种非线性特性进行模拟仿真的方法。

The power system models in MATLAB/ SIMULINK are very convenient for simulation of dynamic process of electrical machines. Therefore, the software is widely used. However, the saturation effects are not considered in the asynchronous machine model and it leads to erroneous results in simulation of certain operation state of asynchronous machines, such as voltage characteristics of asynchronous generator and so on. The purpose of this paper is to provide an improved method to consider the saturation effects based on the library of models in SIMULINK.
