Operational Characteristics of the DFIG-Based Wind Power System Under Non-ideal Grid Conditions
摘要
Wind power systems are often built in areas with rich wind resources, which are mostly remote, far from the main grid, with a fragile grid structure and a complex surrounding electricity environment, where grid voltage jitters, dips and asymmetries often occur, while short circuits and grounding faults in the grid will also cause various grid voltage faults [1, 2], thus having a serious impact on the wind power generator and even the whole wind power system [3, 4].
