Abstract
Abstract: Power quality is the main problem that the industry is facing today. In this paper, an issue i.e. voltage sag of power quality in an isolated power system is considered. The series compensators device thyristor controlled series capacitor is used for improving power quality of isolated power system. The role of the compensator is to mitigate the effects of voltage sag. A control strategy for the SC is developed to regulate power flow. This is achieved through phase adjustment of load terminal voltage. It leads to an increase in the ride through capability of loads to the voltage sags/swells. In this paper Simulation results shows a comparative study of output voltage across a sensitive load without and with Series Compensation. This method of reducing the voltage sag by voltage injection using Series Compensation is more effective. Simulation results using MATLAB/Simulink have been presented. The modeling and simulation of series compensator was implemented in matlab simulink work space. simulation results showed that the proposed series compensator was efficient in mitigating voltage sags and improve the power quality of isolated power system. this approach is different from conventional methods and provide effective solution. If this method is enhanced in future, it could provide much more improved power quality.
