Power Quality Enhancement in an Isolated Power System Using Series Compensation
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
In Isolated power systems the power quality problem is compounded as the drive converter loads are likely to fluctuate in conjunction with mining or exploration areas. The use of compensators in improving power quality of isolated power systems is considered. The roles of the compensators are to mitigate the effects of momentary voltage sags/swells, and to control the level of harmonic distortions in the networks. A control strategy for both series compensator and shunt compensator is developed to regulate power flow. However series compensator reduces harmonics to an acceptable level when compared to shunt compensator. This is achieved through phase adjustment of load terminal voltage. It leads through an increase in ride through capability of loads to the voltage sags/swells. Validity of the technique is illustrated through simulation. Hence series compensator with LC Filter is used in reducing the harmonic distortions in isolated power systems.
