Simulation Analysis of Four-quadrant Operation of Doubly-fed Speed Control System

首先分析双馈调速的基本理论;然后在MATLAB环境下建立系统的仿真模型,分别对系统的启动特性、调速特性以及电动到发电过渡的过程进行仿真与分析。仿真结果表明,该有级双馈调速系统的起动与调速过程,过渡平稳,能在超同步上下频繁过渡,并且可以实现超同步四象限运行。

First, the basic theory of doubly fed speed regulating system is analyzed ;then a system simulation model in MATLAB environment is created,and the startup characteristics,the speed characteristics and the process of electric power transition is simulated and analyzed. Simulation results show that the process of starting and speed regulating of stepped double-fed systems have smooth transition ,frequent transition in super synchronous up and down, and can achieve the synchronization of four quadrant operation.
