Comprehensive Analysis of LCL Filter Interfaced Cascaded H-Bridge Multilevel Inverter-Based DSTATCOM
Abstract: Three-phase two-level voltage source converters are used for distribution static compensator (DSTATCOM) applications and can be replaced by a multilevel inverter. In this paper, an LCL filter interfaced cascaded H-bridge multilevel inverter-based (CHBMLI) DSTATCOM is simulated and its performance is analyzed considering the system parameters. The analysis considers factors including t...
متن کاملGrid Current Regulation of a Three-Phase Voltage Source Inverter With an LCL Input Filter
Many grid connected power electronic systems, such as STATCOMs, UPFCs, and distributed generation system interfaces, use a voltage source inverter (VSI) connected to the supply network through a filter. This filter, typically a series inductance, acts to reduce the switching harmonics entering the distribution network. An alternative filter is a LCL network, which can achieve reduced levels of ...
متن کاملRipple Current Analysis of Three-level Inverter based on SVPWM and Design of LCL Filter
Three-level gird-connected converter is used more and more widely in renewable energy generation system. At the same time LCL filter is also widely utilized in order to achieve lower current harmonic. However, current research about LCL filter is mostly aimed at two-level inverter. The study involving multilevel inverter is much less. When using space vector pulse width modulation, Current tran...
