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(200) for awater sluice gate (100), in particular for a roller sluice gate, preferably ina hydroelectricpower plant (1000), wherein the drive has an electric machine, in particularhas anasynchronous machine (210), in particular an asynchronous motor/generator.According to theinvention, it is provided that- the electric machine, in particular an asynchronous machine (210), has a fanbrake (230), wherein the method comprises the steps of:- disengagement of the fan brake (230) in the case that an insufficient powersupply is indicated,- self-actuated operation of the electric machine, in particular anasynchronousmachine (210), wherein the electric machine, in particular an asynchronousmachine, is operated in generative island operation, in which a rotating fieldisgenerated in a self-actuating manner.
