Line-fault ride-through (LFRT) capabilities of wind DFIG turbine

The penetration of wind power into electrical grids is increased during the recent years. According to grid codes issued by utilities, tripping of wind turbines following power system faults is not allowed. Besides, to provide voltage support to the grid, reactive current supply is necessary. This paper studied the power flow (PF) of two different parts in one network, the first presents the transmission lines and the second presents the distribution lines, a wind DFIG turbine is connected to these different parts of network. A line fault right through (lfrt) is applied on each part of the network. The corresponding voltages are given and compared, then a new solution is proposed to connect the wind turbine to the distribution network and aiming to not disconnect the wind turbine during the line fault. The power system analyses toolbox (PSAT) are used in this work.
