Application Of The Vohepwm Strategy To A Grid-Connected Inverter System
PROCEEDINGS 2018 3RD INTERNATIONAL CONFERENCE ON ELECTRICAL SCIENCES AND TECHNOLOGIES IN MAGHREB (CISTEM)(2018)
摘要
This work presents the application of vector optimized harmonic elimination pulse width modulation (VOHEPWM) strategy to a system comprised of three single-phase full bridge inverters connected to the grid and powered by three DC voltage sources in order to have a reduced THD and almost unity power factor. For evaluating the phase angle of the grid voltage, controlling the current and injecting maximum power, the PLL and Watt-Var controls are employed. The obtained simulation results are presented and analyzed.
