Power quality improvement in power system by using static synchronous series compensator

This paper presents the performance of SSSC for power quality improvement. As nonlinear loads causes the harmonics in the system and therefore the power quality gets reduce because of these non linear load. Hence power quality is study with case I. Non linear load without SSSC & case II. Non linear load with SSSC in IEEE 9 bus system. The diode bridge rectifier is used here as non linear load. Series FACTS devices are most powerful controllers used for power flow, power quality, power oscillation damping and improving transient stability of the power system. Power quality study is carried out with Fast Fourier Transform analysis and Total Harmonic Distortions are obtained which shows the harmonics present in the system. Results are validated by using MATLAB.
