Abstract

Although one of the main problems of the power quality is voltage sag in nuclear installations,
the terminology used for the compensation devices is different. A Thyristor switched capacitor
control is one of the equipment for voltage disturbance mitigation. This paper suggests a
Thyristor Switched Capacitor control for mitigation of voltage sag in nuclear research reactor as a
sensitive load. Performance of the proposed control investigated under different types of voltage
sag magnitudes and is modeled using the user-defined dynamic modeling (UDM) tools in ETAP.
The results show appropriate operation of the proposed control system to examine the developed
technique.
