中文摘要 | 本文提出一種基於時域分析電力系統暫態能量函數( TEF )之電力係統阻尼控制 新策略。此控制策略適合以模糊理論為基礎之統一潮流控制器( UPFC )來實現電力系統中 低頻機電震盪之控制。本文中,模糊控制器之相關理論及其設計程序將有詳細的探討。電腦 暫態模擬之結果將用來證明所提控制法則之優越性。本文提出之控制法則,係採用不同組合 之輸入信號,配合三種不同之統一潮流控制模式,以達最佳之阻尼控制效果。電腦模擬的結 果可證明所提之控制策略具實際可行性及所採用之統一潮流控制器為新一代電力系統控制之 最佳選擇,因為它可提供高度彈性之控制功能模式,非常適合即時電力潮流及快速系統暫態 控制。 |
英文摘要 | In this paper, a novel UPFC damping control strategy based on time-domain analysis of the system trainsient energy function (TEF) is proposed and implemented by using fuzzy controllers to damp low frequency electromechanical power oscillations. The detailed design procedure of fuzzy controllers is addressed. Comprehensive computer simulations have been carried out to verify the proposed control scheme. The control effectiveness of using a combination of different control modes in the UPFC system with respect to different input signals to improve the transient performance of power systems is investigated and discussed in full. The simulation results reconfirm that the proposed control algorithm is practically implementable and the UPFC is the most powerful FACTS device which is able to provide flexible control functions required for the real-time power flow regulation and fast transient control of power systems. |
