摘要： A method for controlling a converter of a wind energy installation. The converter is connected to a rotor of a doubly-fed asynchronous generator for feeding electrical power into an electrical grid and comprises a generator-side inverter, a grid-side inverter, and at least one converter regulator for regulating and/or controlling currents emitted from at least one of the inverters to at least one of the generator and the electrical grid. The method includes detecting a change in electrical voltage present in at least one of emitted real currents and emitted reactive currents at one of the inverters, determining whether the detected change corresponds to a predetermined change, and changing nominal values of at least one of real currents to be emitted and reactive currents to be emitted from the other inverter if the detected change corresponds to the predetermined change.

摘要： A system and method for operating a wind energy installation or wind farm. The system includes a control unit configured to process control variables and a transfer module. The transfer module has an input interface for receiving control commands and an output interface for transmitting control variables to the control unit. The transfer module has multiple transfer logic elements each configured to convert a control command to a control variable.

摘要： A wind park includes at least two wind energy systems each comprising a generator and converter for generating electrical energy and a control system, a park master designed for active and idle power control that transmits a control signal for idle power via a communications network to the wind energy systems, and a connection network feeding generated electrical energy into a grid. The wind energy system can include an idle power regulator and a supplementary regulator, the control signals of each of which are linked together. Thus, a combination of idle power and voltage regulation is achieved that combines the advantages of each. Accordingly, the wind park can have high dynamic and stability notwithstanding erratic changes in the grid.

摘要： A method is provided for operating a wind power plant (15-19) with a rotor-driven (25-29) electric generator (30) for delivering electric power to an electric grid (31) which provides a grid voltage in which, when excess voltage prevails in the grid (31), idle power from the wind power plant (15-19) is fed to the grid (31) in order to lower the voltage. A wind power plant is provided (15-19) with a rotor-driven electric generator (30) for delivering electric power to an electric grid (31) in which when excess voltage prevails in the grid idle power from the wind power plant (15-19) is fed to the grid (31) in order to lower the voltage.

摘要： A converter for a wind energy installation and a method. The converter includes an inverter which drives a generator via a plurality of phases and an intermediate circuit having an intermediate-circuit voltage between an upper and a lower intermediate-circuit potential. The generator is driven with phase potentials at a variable frequency. A shift value is calculated between an extreme phase potential and one of the intermediate-circuit potentials, a separation value is determined between a middle phase potential and the closest intermediate-circuit potential, and an additional voltage is generated using the separation value as amplitude. The phase potentials are shifted through the shift value and the additional voltage is added to the middle phase potential. Accordingly, the switching elements in the converter do not need to be clocked in every second half-cycle resulting in reduced switching losses and increased current load capacity of the converter.

摘要： A method for operating a wind energy installation and a system for implementing the method. An oblique incident flow value, which represents the difference between the wind direction and the direction of a rotor axis of the wind energy installation, and a load value, which represents the load state of the wind energy installation, are determined. A total load value is determined based on the load value and the oblique incident flow value. The rotor rotation speed is reduced when the total load value is above a first limit value. The wind energy installation is shut down when, in addition, a second limit value is exceeded. The method makes it possible to react objectively to oblique incident flows and can reduce a load on a wind energy installation without causing large yield losses.
