Analysis of Three-phase Short Circuit Current of Infinite-capacity Power Supply System
摘要
Abstract
Through the analysis of three-phase short circuit of infinite-capacity power supply system, we find out the short-circuit current is made up by the periodic component ip and non-periodic component i~p. It is because of non-periodic component, the current in the inductor will not be changed instantly in a sudden short-circuit. Because the existence of non-periodic component, the full current curve of short-circuit and time axis is not symmetrical in the transient process. This will lead to the instantaneous maximum amplitude value more than the periodic component of short-circuit.关键词
