中文摘要 | 本研究為一方法論,旨在深入探討並詳論以傳統的「標么法」及新發展的「複數短路容量法」分析短路故障電流計算,由分析方法及計算結果來比較兩種方法之優劣。研究顯示複數短路容量法,因不須選定基準值,參數的轉換與運用比標么法更直接,且其轉換值以及所建立的矩陣式具唯一性,在電腦程式應用與效率方面,此法較標么法為優,若以之為分析方法建立資料庫,將有助於設計電腦輔助短路故障電流計算之研究。此外,本文提出「修正型複數短路容量矩陣法」以直接建立系統矩陣執行運算,在程式應用上更具系統化與發展性。 |
英文摘要 | The purpose of this paper is to compare the conventional Per Unit Method and a newly develop Complex Short Circuit MVA Method for analyzing short-circuit currents of power system. In spite of the complicated process of choosing the base value, the Per Unit Method is commonly used in calculating short-circuit currents. This paper adopts Complex Short Circuit MVA Method instead. In which, the rated capacity or voltage and the impedance of the devices involved are the only parameters needed. By using the proposed method, the conversion quantities and derived matrix are unique. Therefore, it is better than the Per Unit method in both application and efficiency of computer program. If the database is set up with this method, it will be of help for designing computer aided the calculation of short-circuit currents. Besides, this paper proposed a modified Complex Short circuit MVA Matrix Method to build the matrix directly for operating calculation. It will be more systematic and developing in application of computer programs. |
