Modeling and Analysis of Voltage Sag Sources in Distribution Network

Abstract:

The mechanism of voltage sags due to three main voltage sag sources, such as line faults, startup of large induction motor and transformer energization, was analyzed theoretically. Based on the typical structure of the distribution network of a large industrial enterprise, the paper presented a simplified analytical model for voltage sag sources and conducts a test with the above three kinds of voltage sag sources in Matlab/Simulink. The results show the proposed model is correct and suitable for the analysis of distribution network.
