| Abstract: | Power generation and grid stability have become key issues in the last decade. The high penetration of large capacity wind generation into the electric power grid has led to a serious concern about dynamic behavior of the power system and required grid codes for the proper utilization of wind energy. Low voltage ride-through (LVRT) capability of doubly-fed induction generators (DFIGs) during grid faults is one of the core requirements. This paper presents a comprehensive study of the LVRT of DFIGs with grid connection. The paper focuses on the LVRT principles and control of grid connected DFIGs with a detailed theoretical study supported by computer simulations. Transient characteristics and the complicated dynamic behavior of the wind turbine during grid faults are presented. The most challenging problems are investigated in grid connected operation. |
