UPFC控制的交互影响分析———可控参数域计算方法

在回顾和论述一般电力系统控制交互影响,特别是统一潮流控制器(UPFC)控制的交互影响这一问题研究的基础上,以装有UPFC的新英格兰10机39节点系统为研究对象,系统研究了UPFC的控制交互影响与控制器控制运行点之间的关系。为了在讨论UPFC的控制交互影响与控制器控制运行点之间关系的过程中,排除参数整定值这一因素的影响,提出通过分析计算UPFC的可控参数域随其控制运行点的变化,揭示了两者之间的相互联系。

Interaction Analysis of Unified Power Flow Controller by Computing the Controllable Parameter Regions

This paper reviews the recent research on the interactions of FACTS control, especially that on the interaction of multiple control functions of a UPFC. In order to exclude the influence of setting of parameters of UPFC with the variations of its control operating points, it is proposed that the interactions of UPFC control can be studied by computing its controllable parameter regions. In the paper, the New England 10-machine 39-node power system installed with a UPFC is used to demonstrate the effectiveness of the proposed method. By computing the controllable parameter regions of the UPFC, useful conclusions about the interactions of UPFC control are obtained, that have excluded the influence of setting of parameters of UPFC.
