Abstract

This paper deals with power quality disturbance generator for the test of STS in power system. The STS used in this system is composed with SCR thyristors. It is necessary to connect the thyristors in series in high voltage system. The major components consisting the generator are SCR thyristors, series transformers, and sliding type auto transformers, therefore, the system reliability is very high. Operating characteristics of the generator are analyzed in each mode of voltage sag and outage. Simulation is carried out for the system with the rated voltage of 330V and 10MVA power rating.
