| 摘 要： | 针对统一潮流控制器(UPFC)控制系统模型及其控制性能中动、静态品质协调不足的问题,提出一种基于微分代数系统控制理论下的UPFC新型控制系统模型。并结合非线性控制设计中多指标控制设计理念,选取多个目标状态量线性组合为输出函数,运用微分代数系统控制设计方法,设计了统一潮流控制器(UPFC)的新控制策略。最后在单机无穷大系统上对其进行暂态仿真。仿真结果表明,所设计的微分代数控制系统能够很好地解决接入点静态偏移的问题,并有效地控制节点电压和线路的潮流,改善了电力系统的暂态稳定性。

| Abstract: | In view of the model of UPFC and its drawbacks of control performance, we propose a new model of UPFC with differential-algebraic equation. Considering the concept of multi index control design, we select a plurality of target state of linear combination for the output function. The new control strategy of UPFC is derived through the control theory of differential-algebraic control systems. The effects on enhancing dynamic performance of power system and controlling bus voltage and line power flow are illustrated by simulation on a single machine infinite bus system. It manifests the validity and significant advantages of the design approach proposed in this paper. |
