Abstract

A stationary energy generation plant includes a control device that serves to control current and energy flow. The energy generation plant includes at least one mechanically driven rotor and a generator mechanically coupled to the rotor. To this end, power electronics operationally connected to the generator enable variable energy flow from the rotor through the generator and the power electronics to a load. In order to compensate for vibrational loads on the generator side, at least one current control is made possible by means of a first intermediate circuit storage of the power electronics. In order to compensate for mechanical vibrational loads and transients of a drivetrain, an energy flow control is provided by means of at least one additional second intermediate circuit storage disposed in the power electronics and having a multiple of the storage capacity of the first intermediate circuit storage.
