METHOD FOR CONTROLLING A WATER SLUICE GATE DRIVE FOR A WATER SLUICE GATE HAVING AN ELECTRIC MACHINE, SERVICE CONNECTION, WATER SLUICE GATE DRIVE AND HYDROELECTRIC POWER PLANT

摘要

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.

1. A method for controlling a water sluice gate drive for a water sluice gate in a hydroelectric power plant, the method comprising:
disengaging a fan brake of an asynchronous machine in the event that an insufficient power supply is indicated; and in response to disengaging of the fan brake, actuating an operation of the asynchronous machine, wherein the asynchronous machine is operated in a generative island operation, wherein a rotating field is generated in a self-actuating manner.
