Disclosed are a grid-connected filter and a method for designing the same. The grid-connected filter is connected between a converter and a grid-connected input terminal which are converted to AC power of a predetermined frequency after converting DC power to the AC power by wind power generation with being connected to an aerogenerator. The present invention comprises: a converter side inductor connected between a transformer and the converter, a node connecting the transformer to the converter side inductor, and a filter capacitor connected between grounds. The grid-connected filter may be an LCL filter which is to use an equivalent inductor of the transformer for a grid-connected side inductor disposed between the node and the grid-connected input terminal. |
