摘要

为了简化双馈电机矢量控制系统所采用的基于电压正弦脉宽调制技术的控制方法

引入电流滞环跟踪脉宽调制技术

并针对所设计的滞环矢量控制系统设计了一种开环转速观测方案.该方案直接利用转子电流在同步旋转坐标系中的参考值分量而避免了对实际电流分量的计算

从而简化了观测器设计并改善了观测效果.简化后的控制系统不仅提高了响应速度而且不依赖电机参数

所设计的开环速度观测方案在一定程度上克服了传统开环速度观测的缺陷.通过PSCAD/EMTDC软件仿真验证了控制系统的有效性和转速观测方案的准确性.

Abstract

As one of the advanced technologies

the variable speed constant frequency doubly-fed induction generation has been widely used nowadays and the usual vector control algorithms are mostly based on voltage sinusoidal pulse width modulation technology. In this paper the current hysteresis pulse width modulation technology is introduced to simplify the control system. An open-loop speed observer is designed according to the hysteresis vector control system. By using the rotor current reference components instead of the real current components

the observer design is simplified and observing effect is evidently improved. The dynamic respond performance becomes better in hysteresis vector control system

and the whole control process gets independent on any electric machine parameters. The proposed speed observer overcomes some of the disadvantages of the traditional open-loop speed observers. PSCAD/EMTDC simulation software is employed to test the proposed scheme

and the results demonstrate the efficiency of the control scheme as well as the speed observer.
