中文摘要 | 三相變壓器為輸配電重要基本設備,如何確保其安全穩定運作及延長使用壽命是重要課題。三相變壓器投入系統時,常因鐵心磁飽和引起的暫態湧入電流造成保護電驛誤動作及變壓器損害。本文提出三相非同步法對變壓器湧入電流進行抑制,並以實驗驗証其優越之效果。提出的方法對變壓器之暫態過電流能有效消除,對湧入電流衍生的過電壓也可有防止。此法可應用至三相變壓器保護電驛系統,提升變壓器保護功能。 |
英文摘要 | Three-phase transformers are key equipments in power systems and power plants. Security, stability and increasing life of transformers are important to system operation. When a three-phase transformer is energized, the inrush current due to flux saturation in the core results in a malfunction of the differential relay and also causes a stress impact to the transformer. These have a bad effect on the security and stability of power system. In this paper, non-synchronous suppressing method is proposed to suppress the inrush current of three-phase transformers. The overvoltages caused by inrush current can also be avoided. The proposed method is examined by experiment. It has excellent performances for suppressing inrush current. The proposed method can be applied to improve the protective relaying system of three-phase transformers. |
