"Device For Regulating A Double Fed Asynchronous Machine"
Abstract: The invention relates to a device for controlling a double-fed asynchronous machine (4), preferably for a power plant, in particular for a wind or water power plant, comprising an indirect converter (6) which is connected on the rotor side to the double-fed asynchronous machine (4), the indirect converter (6) comprising a rotor-side converter (20) and a line-side converter (24), and at least one control element (8) is provided for controlling the indirect converter (6), at least one software-based and/or hardware-based damping element (40, 46, 48, 120) being provided which has changeable damping characteristics. The invention also relates to a method for controlling a double-fed asynchronous machine (4), comprising an indirect converter (6) and a device according to the invention in which mains characteristics are determined, in particular measured, hardware and/or software-based damping elements (40, 46, 48, 120) being provided which have changeable damping characteristics, and the damping characteristics of at least one hardware and/or software-based damping element (40, 46, 48, 120) are adapted subsequently. The invention also relates to a computer program, to a computer program product and to a wind or water power plant for generating electrical energy with a double-fed asynchronous machine. FIG. 1 is provided for the Abstract.
