摘要

本文的主要目的是利用一种先进的统一潮流控制器(UPFC)控制方法来提高电力系统的动态控制性能。该控制器基于滑模控制技术,保证了快速的响应时间、精确的控制动作和几乎完全解耦的有功和无功控制。为了减少能量存储设备,从而减少功率损耗和延长UPFC系统的使用寿命,使用了具有最低存储要求的交流-交流转换器。这些变换器通常被称为稀疏矩阵变换器,它们基于矩阵变换器技术,可以保证AC/DC和DC/AC的转换,而不需要大多数AC/DC - DC/AC变换器中存在的中间电容器组。采用稀疏矩阵变换器建立了UPFC模型,并设计了具有良好稳态和动态响应的控制器。

P-Q decoupled control scheme for unified power flow controllers using sparse matrix converters
The main aim of this paper is to improve the dynamic control performance of power systems, using an advanced control approach for Unified Power Flow Controllers (UPFC). The proposed controller, based on sliding mode control technique, guarantees fast response times, precise control actions and an almost completely decoupled active and reactive power control. To reduce energy storage equipment, with consequent reduction of power losses and lifetime increase of UPFC systems, AC-AC converters with minimum storage requirements are used. These converters, usually known as Sparse Matrix Converters, are based on Matrix Converter technology and guarantee AC/DC and DC/AC conversion without the intermediate bank of capacitors, present in most AC/DC - DC/AC converters association. UPFC model is presented, using Sparse Matrix Converters, and the system controllers are designed to allow both a good steady-state and dynamic response.
