Analysis and Application of AC Short Circuit Current Rising Rate Feature and Short-circuit Fault Diagnostic
Zhou Shiwa · Ship Electronic Engineering · 2014
This article discusses the main feed of the short-circuit current sources of ship power system firstyl,A system model of ship power system is created for deriving short-circuit current rate of rise of mathematical formulas,and then the determinants of short-circuit current rising rate are analyzed for the perspective of ship power system and the difference of short-circuit when the short-circuit current trends angle of impact on the current rate of rise is discussed.By comparing the simulation,the selection methods and conditions are iven for short circuit fault diagnosis on certain specific ship power system by the reference current rate of rise.The method of reference current rate of rise selection is tuning set as a reference for the current rate of rise of the ship power system fault diagnosis.
