摘要
随着柔性交流输电(FACTS)控制器在电力系统中的广泛应用,FATCS控制器之间可能存在交互影响作用,从而给电力系统的运行和控制带来负面影响。该文介绍了相对增益(RGA)方法的基本原理,并用RGA原理分别研究了含SVC和STATCOM的单机无穷大系统和含2个SVC的两区域四机电力系统中FACTS控制器之间交互影响的强弱,时域仿真结果与RGA原理的分析结果一致,表明了RGA原理分析FACTS控制器之间交互影响作用的可行性和有效性。
With the wide applications of flexible AC transmission system (FACTS) controllers in power systems, a potential risk, the interaction between FACTS controllers, is emerging and may impose negative influence on power system operation and control. This paper proposes the relative gain array (RGA) theory to assess the interaction between FACTS controllers. Two cases, a single machine infinite bus (SMIB) power system with static var compensator (SVC), static synchronous compensator (STATCOM) and two-area power system with two SVCs, are investigated to demonstrate the RGA approach, which can provide an indicator to quantify FACTS controllers’ interactions. The detailed simulation results accord with the analysis results by RGA method, which demonstrates the effectiveness of RGA method in analyzing interactions of FATCS controllers.
