Description
Summary:This paper describes modular software for the automated assessment and visualization of voltage sag performance. The software allows in-depth analysis of voltage sag performance of the individual buses, the performance of the entire network at different voltage levels and inside the industry facility. The prediction and characterization of voltage sag, identifying the area of vulnerability and the area affected by the fault, and the propagation of voltage sags can be done automatically taking into account different fault statistics for symmetrical and asymmetrical faults, and different fault distributions. The module also considers the protection system and effects of its failure on the duration of voltage sags. The software capabilities are demonstrated on a generic distribution network and the results of the module are presented in the graphical and tabular form using specially developed graphical user interface (GUI).
