this paper presents a novel method for short-circuit current calculation, using zero impedance branch to simulate electrical equipment ( such as circuit breaker ) 提出了將電氣設(shè)備(如斷路器等)用一條零阻抗支路模擬的短路電流計算方法。
it utilizes zero impedance branch characteristic, combining structure-transform and structure-static short-circuit current calculation method to calculate the short-circuit current directly through the electrical equipment when short-circuit fault takes place at the two sides of the electrical equipment, and settles the problems that the traditional method cannot directly figure out the short-circuit current 該方法利用零阻抗支路特點(diǎn),結(jié)合定結(jié)構(gòu)和變結(jié)構(gòu)短路電流計算方法,能夠直接求出在電氣設(shè)備兩側(cè)分別發(fā)生短路時,通過電氣設(shè)備(如斷路器)的短路電流,從而合理地解決了傳統(tǒng)的故障分析方法不能直接求出流過設(shè)備的短路電流的問題。
zero impedance meaning:[Electronics] 1. Absence of impedance (a theoretically ideal condition). 2. In some circuits, the lowest impedance level, to which all other impedances are referred.
