中文摘要 | 假設系統的元件相互間無耦合的現象,本文提出一個快速且直接的方法以計算弱 質網目工業配電系械的三相短路故障電流。其解析母線驅動點阻抗的主要步驟有二,在主步 驟 1 可分為 3 個次步驟:(1) 轉換弱質網目的系統為輻射型系統;(2) 組成一棵解三相短 路故障電流的樹;(3) 計算輻射型系統母線的驅動點阻抗。 主步驟 2 則對各次網路分別組 成母線阻抗矩陣 Zbus,並找出各次網路內部母線的驅動點阻抗。 本方法的優點為:(1) 主 記憶體容量少; (2) 運算時間短,尤其在大系統更能顯示此項特性。 二個母線數目分別為 39 及 71 個之模擬系統的結果可說明、印證本方法的優異性能。 |
英文摘要 | Assuming there is not mutual coupling between the elements of a system, this paper presents a fast and direct method for obtaining three - phase short circuit fault current solutions of weakly meshed industrial distribution systems. The method to solve bus driving point impeadance is divided into two main steps. The first step is composed of three sub-steps: (1) converting weakly meshed system into radial type system; (2) building a tree to slove three-phase short circuit fault currents; (3) calculating the bus driving point impeadances of radial type system. The second step is to build the bus impeadance matrix Zbus of every sub-network, and then to obtain corresponding interior bus driving point impeadance. The essential advantages of this method are: (1) small storge size, (2) short calculation time; especially for large systems. The simulation results of 39 and 71 bus systems illustrate the above merits of this method. |
