The invention relates to a wind energy plant testing device for the defined generation of network errors, comprising an output (21), to which a wind energy plant to be tested can be connected, and an input (26) for connecting a network (9), wherein a switching device (23, 24) is provided for connecting an electric interference component with respect to a network parameter. According to the invention, an autotransformer is provided for the electric interference component (3), wherein the network having no interference is applied to a primary winding connection (31), and a network having interference with respect to the network parameter is output at a secondary winding connection (32). In this manner, the testing spectrum can be expanded in a simple manner to include stability to voltage peaks using conventional energy technology components. |
