摘要/Abstract

摘要：

双级矩阵变换器（TSMC）由于其优良的电气性能,在统一潮流控制器（UPFC）中具有较大的应用价值。本文首先分析了TSMC的双空间矢量调制策略（DSVM）,建立了TSMC-UPFC串联侧的预测模型,在此基础上提出了基于TSMC-UPFC串联侧电流预测控制策略。仿真研究表明,本文提出的控制策略对线路潮流具有很好的调节效果,可以快速、精确地跟踪参考值,超调量小,具有较好的动静态性能。

Abstract:

Two stage matrix converter (TSMC) because of its excellent electrical performance, in unified power flow controller (UPFC) has great application value. This paper analyzes the space vector modulation strategy of two TSMC and predictive model was established on TSMC-UPFC series side, on the basis of the series side predictive current control strategy based on TSMC-UPFC is proposed. Simulation results show that the control strategy proposed in this paper has good adjustment effect on line flow, can quickly and accurately track the reference value, small overshoot, and has better dynamic and static performance.

Key words: Unified power flow controller, two stage matrix convertor, space vector modulation, predictive control
