voltage sags are one of the most important power quality problems challenging the utility industry voltage sags can be compensated for by voltage and power injection in to the distribution system The use of series compensators (SCs) in improving voltage quality of isolated power systems is con-sidered.

The roles of the comp-ensators are to mitigate the effects of momentary voltage sags or swells, and to control the level of harmonic distortions in the networks. A control strategy for the SC is developed to regula-te power flow. This is achieved through phase adjustment of load terminal voltage. It leads to an increase in the ride throu-gh capability of loads to the voltage sags/swells. Validity of the technique is illustrated through simulation.
