本文以改善UPFC 動態性能為出發點，指出了UPFC 研究中存在的問題：1 目前針對UPFC 系統所建立的模型不完整，使得控制系統設計中存在缺陷；2 沒有一個有效、合理的潮流調節器參數設計方法，使得控制系統性能得不到很好的驗證。結合UPFC 系統級和裝置級的模型分析，考慮了各變量之間的相互影響，構建了一個更加完整的控制系統，改善了UPFC 系統動態性能。另外，給出了利用頻率特性法，通過繪制系統Bode 圖來確潮流定調節器參數的方法。最后，在國內首先對UPFC 的性能作了實驗研究，得到了大量有效的實驗結果。
Abstract: Base on improving the dynamic performance of UPFC, this paper points out the following two problems in the present study on UPFC. (1) The model of UPFC is not integrated so as to have flaws in control system design of UPFC.(2) There is no effective and reasonable method to deign the parameter of the power flow controller. So the control system
characteristic of UPFC is not tested well. Combining the UPFC system model and UPFC device model, this paper considers
interaction among different variables and proposes a more integrated control system of UPFC. The frequency characteristic
method is presented and the reasonable parament of power flow controller is obtained with the system Bode plot. As a result, the dynamic system performance of UPFC is improved. Experimental results based on a 15kVA experimental system show the above control system provides satisfactory performance.
