METHOD FOR CONTROLLING A SLUICE DRIVE FOR A SLUICE, SAID SLUICE DRIVE HAVING AN ELECTRICAL MACHINE, OPERATING CIRCUIT, SLUICE DRIVE, AND WATER POWER PLANT.

摘要

The invention relates to a method for controlling a sluice drive (200) for a sluice (100), in particular for a roller-type sluice, preferably in a water power plant (1000), wherein the drive has an electrical machine, in particular an asynchronous machine (210), in particular an asynchronous motor/generator. According to the invention, provision is made for the electrical machine, in particular asynchronous machine (210), to have a fan brake (230), wherein the method comprises the steps of: releasing the fan brake (230) if an insufficient power supply is indicated, automatically operating the electrical machine, in particular asynchronous machine (210), wherein the electrical machine, in particular asynchronous machine, is operated as a generator in island mode in which a rotating field is automatically generated.

The invention provides an immunogenic composition comprising one or more GBS conjugates and one or more antigens selected from: a) cellular or acellular pertussis antigen, b) a tetanus toxoid, c) a diphtheria toxoid and d) an inactivated polio virus antigen, wherein each GBS conjugate is a group B streptococcus capsular saccharide conjugated to a carrier protein. The invention also provides a method for raising an immune response in a patient, comprising the step of administering to the patient a composition of the invention.
