中文摘要 | 三相變壓器已成為能量傳輸中不可或缺的基本設備。三相變壓器之安全、穩定運作即成為最重要之課題。然而當三相變壓器在投入系統時,常因鐵心之磁飽和造成很大的暫時過電流,此暫態湧流易造成保護電驛之誤動作,對變壓器也易形成衝擊,對於供電之安全性、穩定性具有不良影響。本文應用最佳三相非同步法對變壓器湧入電流進行抑制,並據此設計三相變壓保護系統,經實驗驗証具有優越性能。 |
英文摘要 | Three-phase Transformers are key components in power systems and power plants. The security and stability of three-phase transformers are both important, and necessary to system operation. When a three-phase transformer is energized, the inrush current due to flux saturation in the score results in a mal-function of the differential relay, and also causes a stress impact to the transformer. These have an adverse effect on the security and stability of the power system. In this paper, an optimum non-synchronous switching-on suppression method of three-phase transformer's inrush current is applied to design the protective system of a three-phase transformer. The active protective strategy is examined by means of experiment, and shows excellent performance. |
