Abstract

This article examines stability evaluation of multi-voltage converters based on static electricity component only (Static compensator). The major purpose of this study is to maintain the voltage balance by compensating the reactive power in electrical supply. By providing reactive power support and voltage stabilization, STATCOM helps mitigate voltage sags, flickers, and other power quality issues. It enhances the overall reliability and performance of the power system, reducing the likelihood of equipment damage or operational disruptions and it can indirectly help mitigate harmonics in the transmission system. The overall performance is also comparable using 110kV transmission with and without STATCOM. In this paper, a fuzzy logic controller approach is adopted to reduce total harmonic distortion (THD) and thus increase power efficiency.
