A High Performance PWM Voltage Source Inverter Used for VAR Compensation and Utility Grid Stability Improvement
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
A high performance advanced static VAR compensator (ASVC) which uses a Pulse Width Modulation (PWM) voltage source inverter is presented and analyzed in this paper. A fast control approach of the ASVC system has been implemented for applications that require leading or lagging power compensation. The proposed control strategy is based on an explicit control of the reactive power, implicit of the voltage amplitude of the capacitor of the dc side and is more flexible. The analysis of the simulation results, inserted in this paper, reveal the technical feasibility of using such an ASVC to improve the stability of the infinite bus system and allow us to conclude that the use of the inverter as compensator of reactive power brings better performances than classical ones.
