Abstract:
Large scale wind turbines tripping accidents have occurred repeatedly,which seriously affect the wind power consumption and power grid security. When the grid voltage drops,the resection of large wind farm will affect the stability of the grid,so it requires the wind generators to have LVRT ability to ensure themselves to keep parallel operating continuously when voltage drops. To study the impacts of wind turbines integrated with grid,the resistance value and switching strategy of crowbar are discussed. And the relation between the protection of DFIG during low voltage fault and the dynamic characteristic of grid is established from the points of generator operation constrains and district grid voltage stability. Doubly fed wind farm is built to validate the effectiveness of crowbar protection by using DIgSILENT. Besides,the low voltage ride through characteristics of doubly fed wind turbine are studied under different fault conditions. The research results can provide references for the grid operation and the stable operation of the wind turbine.
