The invention relates to a power generation plant, driven by a water current, comprising The invention is characterized in that the drive train comprises a controllable hydrodynamic coupling for exclusive transmission of power to the electric generator.

Drive train for an immersion energy production system

A drive train having a power-split transmission for distributing the power to at least one first power branch and at least one second power branch. The first power branch at least indirectly drives an electric generator, while a connection is established between the first power branch and the second power branch by a hydrodynamic circuit, which is disposed at the output end of the power-split transmission. The power flow is influenced in such a way by the hydrodynamic circuit that the speed at which the electric generator is driven is substantially constant.

Control procedure for a flow machine, wherein the flow machine comprises a turbine, which picks up power from a wind or water current, and a driveline, which transfers power from the turbine to an electric generator connected to an electricity grid of constant grid frequency. A power distribution transmission arranged on the input side of the driveline splits power to first and second power branches. A hydrodynamic convefler connects the first and second power branches on the output side of the driveline and the first power branch drives the electric generator with constant speed. The reaction member of the hydrodynamic converter is set to a constant position for a turbine speed below a chosen threshold and above the threshold the reaction member is controlled to maintain a medium speed of the turbine being a function of the momentum picked up by the turbine.

A hydrodynamic converter is provided having a pump wheel, which is flowed through in operation from the inside to the outside; a turbine wheel, which is flowed through in operation from the outside to the inside; guide blades between the pump wheel and the turbine wheel; and guide blades between the turbine wheel and the pump wheel. The converter can have a speed ratio of between the speed nof the turbine wheel and the speed nof the pump wheel of between 1.2 and 4 at approximately even or falling &#x3bb; progress. The converter can also have different speed ratios between pump and turbine, which can be realized with the ratio R/r equal to or larger than 1.

Hydrodynamic converter

A wind power plant connectable to an electric grid is provided that has at least three control levels. A controller controls an angular position of the rotor blades and/or controls a setting of the reaction member of the hydrodynamic speed transformer and/or controls the power electronics of the generator. The controller is provided with predetermined setpoint characteristics depending on operating states of the wind power plant and/or the electric grid or characteristics of the wind.

The invention relates to polymer ceramic composite materials with a virtually zero shrinkage compared to the original model after concluding partial pyrolysis and with a comparable thermal expansion behavior (preferably in an application range of 400&deg; C. or less) to metal construction materials, in particular gray cast iron or steel, which are obtainable by methods described below; corresponding composite constructions and molded parts; and methods for producing and using these materials, composite constructions and molded parts. The polymer ceramic composite materials can for instance be used instead of or in contact with steel or gray cast iron temperature-proof molded parts, predominantly in mechanical engineering, without postmachining after the creative forming.

The displacement machine is intended in particular for use as a pump, and has a working area, formed in a housing, which working area is limited by two end walls and a casing, and is accessible via an inlet and an outlet for a working medium. At least one rotor, movably disposed in the housing, subdivides the working area, and a guide gearing for rotor control is connected to a drive apparatus located outside the working area. The invention has as its object to propose a displacement machine which can be manufactured less expensively and with less weight than known displacement machines of this type, and in particular can be operated without any special lubricant for the bearings. This object is attained in that the rotor, or respectively the rotors, is or are, supported at least partially inside the working area, and in that the bearing or bearings, disposed inside the working area, is, or are, accessible for the working medium, and is, or are, designed as rolling bearing made of ceramic materials, making possible operation of the displacement machine without lubricants. Contamination of the working medium from lubricant is thereby practically excluded.
