Abstract
The invention relates to a method for controlling a water sluice gate drive for a water sluice gate, in particular for a roller sluice gate, preferably in a hydroelectric power plant, wherein the drive has an electric machine, in particular has an asynchronous machine, in particular an asynchronous motor/generator. According to the invention, it is provided that the electric machine, in particular an asynchronous machine, has a fan brake, wherein the method comprises the steps of: disengagement of the fan brake in the case that an insufficient power supply is indicated, self-actuated operation of the electric machine, in particular an asynchronous machine, wherein the electric machine, in particular an asynchronous machine, is operated in generative island operation, in which a rotating field is generated in a self-actuating manner.
