A benchmark system for digital time-domain simulation of a pulse-width-modulated D-STATCOM

A benchmark system for studying the sinusoidal pulse-width-modulated distribution-static synchronous compensator (D-STATCOM) is proposed. A simple multifunction controller is provided to offer DC bus voltage control, power factor correction, and AC voltage control. Simulation results are presented and compared to experimental results obtained from a 10 kVA laboratory D-STATCOM. Excellent agreement between simulation and experimental results is obtained, validating the simulation output.
