Voltage sag is a major power quality problem, which could disrupt the operation of voltage sensitive equipment. The fault in transmission and distribution lines of the power system creates voltage sags. It's important to analyze the voltage sags caused by faults in high voltage systems to solve the voltage sag problems of customers. A fully digital power system simulation tool, EMTDC/PSCAD, was applied to build a system model of a large power customer, a large quantity of simulating calculation about voltage sags was carried out. It demonstrates the possible application of the platform and affordable means to study different cases of these problems.
