基于奇异值分解方法的FACTS交互影响分析

针对电力系统中多台灵活交流输电装置(FACTS)控制器之间可能存在的交互影响问题,以可控串联补偿器(TCSC)和静止无功补偿器(SVC)2种FACTS控制器为研究对象,提出了一种基于奇异值分解(SVD)的交互影响分析方法,定量分析了新英格兰10机39节点电力系统中同时装设TCSC和SVC时,2台FACTS装置之间可能存在的交互影响问题及电气参数对交互作用的影响。时域仿真结果验证了所提出的方法的有效性,表明电气距离的改变对TCSC与SVC间的交互作用有着较强的影响,增加电气距离,交互影响变弱,缩短电气距离则会加重两者之间的交互影响。

Analysis on the Interaction of FACTS Controllers Based on the SVD Method

To analyse the possible interactions among multiple flexible AC transmission system(FACTS) controllers in a power system,an approach based on the singular value decomposition(SVD) is proposed for the analysis of interactions between thyristor controlled series compensator(TCSC) and static Var compensator(SVC).The proposed approach is used to analyse the interactions between a TCSC and a SVC installed in the New England Test Power System(NETPS).The simulation results verify the effectiveness of the proposed approach.And it indicates that the electrical distance has a strong influence on the interactions between TCSC and SVC.The interactions will be weakened when the electrical distances are increased,and vice versa.
