| 摘要: |
| 多个灵活交流输电系统(FACTS)元件接入系统中各FACTS元件控制器间存在负的交互影响。针对已有的变量配对方法和交互影响分析方法存在的局限和不足，根据NI指数理论，提出适用于大规模、多变量的基于NI指数的多控制变量配对方法，运用该方法找到使得控制器间交互影响最小的控制变量最优配对组合。通过对最优配对组合进行分析，得到最优配对组合中与交互影响的严重程度关系最大的一组输入-输出变量。依据这一关系，制定出相应的多FACTS元件协调投入控制策略。以第二代串联型FACTS元件——静止同步串联补偿器(SSSC)为例，通过仿真系统的计算与分析，证明了所提出的多控制变量配对方法的可行性；并利用PSCAD搭建了含多个SSSC元件的系统进行仿真验证，证明了所制定的协调投运策略是可行、实用的。 |

| Abstract: |
| There are negative interactions among the controllers of multiple FACTS components in a system. Aiming at the limitations and deficiencies of existing variable pairing methods and interaction analysis methods, a pairing method suitable for large-scale and multiple control variables is proposed based on the existing NI index theory, which is used to find the optimal pair combination for making the interactions among multiple controllers minimal. The optimal pair combination is then analyzed to obtain a group of input-output variables, which is mostly related to the severity of interactions, and a corresponding control strategy is set accordingly for the coordinated commissioning of multiple FACTS components. With the second-generation series FACTS devices, SSSC(Static Synchronous Series Compensator),as an example, the simulative calculation and analysis prove the proposed control variable pairing method feasible. A simulation system including multiple SSSCs is built with PSCAD and results show the proposed coordinated commissioning strategy feasible and practical. |
