Modelling Of PSO - Multilevel Converter To Compensate Unbalanced Voltages

open access: yesTurkish Journal of Computer and Mathematics Education (TURCOMAT), 2021
This paper proposes a concept of multilevel H-bridge converter based STATCOM to compensate the voltage fluctuations. The control structure of STATCOM is implemented with conventional PI and PSO controllers. The reference signals required for the PSO controller is obtained by dc link voltage of STATCOM.

Unbalanced Load Compensation

open access: yesInternational Journal of Advanced Research in Science and Technology, 2012
Practical systems rarely have perfectly balanced loads, currents, voltages or impedances in all three phases. The analysis of unbalanced cases is greatly simplified by the use of the techniques of symmetrical components. An unbalanced system is analyzed as the superposition of three balanced systems, each with the positive, negative or zero sequence of
