摘要
通过一实例 ,讨论报告了统一潮流控制器的多个控制器之间存在的交互影响及在负交互影响下 ,多个控制器设计安排的不合理性。文中建议对统一潮流控制器应设计 1个多变量控制器来完成其具有的多个控制功能。并给出了这样 1个多变量控制设计的成功实例。
One of the most important features of a Unified Power Flow Controller (UPFC) is its multiple control functions which may be implemented by multiple controllers. In this paper, the dynamic interactions among the multiple controllers of the multiple functional UPFC are investigated. Examples presented in the paper demonstrate that due to the interactions, separately designed and individually implemented stable UPFC controllers may result in poor control performance and even the closed loop system instability when they are in joint operation. Hence it is suggested that the multiple functional UPFC is treated as a Multi Input and Multi Output (MIMO) control system and it is demonstrated that a single multivariable controller can be designed successfully for the UPFC to perform the multiple control functions which takes full account of the control interactions in the MIMO UPFC system and guarantees the closed loop system stability.
