摘要
Abstract
The control structure for grid connected three-phase two-level voltage source converter (VSC) under distorted grid voltage conditions was researched. Grid voltage is distorted by balanced and unbalanced voltage dips and higher harmonics. To address the problem,the control structure of converter was presented. The control system is a modification of voltage oriented control (VOC) based on dual vector current controllers (DVCC). Grid synchronization under distorted voltage is achieved by employing phase locked loop (PLL). Simulation and experimental results illustrate properties of proposed system.关键词
