20130045100 | ROTOR BLADE DRAIN - The invention relates to a rotor blade for a wind power plant comprising a rotor blade body, wherein the rotor blade body encloses a hollow space, wherein the rotor blade body comprises a penetration for draining the hollow space, and a functional element, wherein the functional element is displaceably connected to the rotor blade body and is disposed at the penetration. According to the invention, the functional element can be transferred from a closed position into an open position, wherein the functional element can be displaced purely by translation. Improved drainage is thereby achieved and clogging of the drain is prevented, with reduced noise production. | 02-21-2013 |
20130027992 | METHOD FOR INPUTTING POWER AND POWER INPUT SYSTEM - The invention relates to a method for inputting power into a multiphase alternating current grid by means of a transformer which is electrically interconnected between the alternating current grid and a number of input phases corresponding to the number of grid phases of the grid, wherein at least one voltage characteristic of one of the grid phases is determined, and an input of reactive currents occurs as a function of a previously determined deviation of the voltage characteristic of the at least one grid phase relative to a corresponding target voltage characteristic. It is provided that the deviation of each one of the voltage characteristics is determined, and the input of the reactive currents in case of deviations that are asymmetrical with respect to the symmetry of the target voltage characteristics is an asymmetrical input of the reactive current with respect to the respective input at the input phases. | 01-31-2013 |
