ENERGY CONVERSION DEVICE WITH HYDRAULIC DRIVE

摘要

The invention relates to an energy conversion device, for example, for wind power systems for higher outputs, for example, above 2 MW. The rotational speed of the wind turbine and the output rotational speed of the hydraulic motor (18) may be controlled independently of one another. The higher outputs are achieved by multiple uses of functionally identical components. The constant rotational speed of the drive shaft (17) of the generator (22) allows the use of a synchronous generator or asynchronous generator with slip regulation. The invention further relates to a method for operating an energy conversion device.
