| 摘要 |
The invention relates to a device for regulating a double-fed asynchronous machine (4), preferably for a power generation plant, particularly for a wind turbine or hydroelectric power plant, comprising an indirect converter (6), which is connected to the double-fed asynchronous machine (4) on the rotor side, wherein the indirect converter (6) comprises a converter (20) on the rotor side and a converter (24) on the power-grid side, and at least one control element (8) is provided for regulating the indirect converter (6), wherein at least one software- and/or hardware-based damping element (40, 46, 48, 120) having variable damping characteristics is provided. The invention further relates to a method for regulating a double-fed asynchronous machine (4) using an indirect converter (6) and a device according to the invention, wherein power-grid characteristics are determined, particularly measured, wherein hardware- and/or software-based damping elements (40, 46, 48, 120) having variable damping characteristics are provided, and the damping characteristics of at least one hardware- and/or software-based damping element (40, 46, 48, 120) are subsequently adapted. The invention further relates to a computer program, a computer program product, and a wind turbine or hydroelectric power plant for generating electrical energy using a double-fed asynchronous machine. |
