JEE_V7_N2_RP4 P. Venkata Kishore Rama Reddy Journal on Electrical Engineering 2230 – 7176 7 2 26 33 Distribution Statics Synchro- Nous Compensator (D-STATCOM), Voltage Source Inverter (VSI), Push Pull Inverter, Power Quality, FACTS The D-STATCOM is a shunt connected FACTS device which supplies reactive power to the load to improve the voltage stability of the load buses. The D-STAT COM in multi bus system is capable of reducing the losses and improving the voltage regulation. This work deals with the comparison of Push Pull and Voltage Inverter based D-STATCOM for multi bus system. Eight bus system is modeled using the elements of SIMULINK. The models are developed for eight bus systems with and without D-STATCOM. The two D-STATCOM systems are compared with respect to total harmonic distortion and reactive power comparison. The D-STATCOM is studied with respect of the voltage stability improvement at the load buses. The results of VSI based D-STATCOM system are compared with those of Push pull inverter based D-STATCOM system. October - December 2013 Copyright © 2013 i-manager publications.
