中文摘要 | 電力系統偶而會發生短路故障,短路故障電流一般都很大,必須藉由保護設備 自動隔離故障,以免造成更大的損害。因此,在設計電力系統時,必須先計算電力系統各 處故障電流的大小,以選擇足夠啟斷容量的保護設備。 但是,一個大型電力系統的故障電流之計算,如果經由人工來求之,此龐大的訐算將 是非常繁雜、極費時、費力,甚至容易計算錯誤。因此,實在有必要經由電腦輔助分析, 以便達到計算準確、省時、省力等目的。 計算電力系統故障電流之各種方法中,"匯流排阻抗矩陣法,,是極佳利器,本軟體 程式就是採取此種方法,來實現電力系統故障電流之電腦輔助分析。本程式亦採取各種電 腦軟體的設計技巧,具有"使用者親和性"(user friendly)之功效,以達到"易學易用" 及"操作省時"之目的。 |
英文摘要 | Short circuits occasionally occur in power system, and fault currents are abnormally high in general. It is necessary to use protective devices to automatically isolate faults in order to prevent the power system from more severe damage. Therefore while designing the power system, it is necessary to calculate the fault currents within everywhere in the power system in order to select the protective devices of adequate interrupting capability. But, if the large amount of calculation of the fault currents in the large power system is done by human manipulation, it ",ill be rather tedious, time- consuming, laborious , and evento easily result in invalid calculation. Thus, it is necessary to be by means of computer aidedanalysis to achieve the purpose of the calculation to be accurate, time-saving, labor-saving. Within several methods for calculating fault currents in power system, the bus impedance matrix method is excellent. This software program just uses this method to implement the computer aided analysis of fault currents in the power system. This program also uses several techniques of software design to have the performance of "user friendly", and achieves the purpose of "easy to learn and easy to use" and "operating time-savingly". |
