Implemented a small scale laboratory based Thyristor switched capacitor - thyristor controlled reactor (TSC-TCR) type static var compensator (SVC). The automatic control circuit has been implemented using microcontroller and tested with the Single Machine Two Bus Test system (SMTB) without and with SVC. Experimental results are presented and P-V Curves have been drawn for both the cases. Automatic control circuit have been designed and fabricated using LPC 2148 Microcontroller. The same test system was tested with SVC automatic control circuit and experimental results have been presented in this paper. The P-V Curves of the SMTB Test system with and with out SVC have been plotted which shows the effectiveness of SVC on Voltage Stability improvement.
