摘要： A method for regulating a wind energy installation including a rotor-driven generator, a converter connected to the generator, and a controller that regulates power emitted into an energy transmission system to within a limit value involves determining a maximum current value in a connection path, determining a current reserve value for power emitted into an energy transmission system, and determining a correction value for following a limit value of the emitted power from the maximum current value and the current reserve value. The wind energy installation and the method for its regulation also includes the use of a limitation device configured to set a phase angle between an emitted current and voltage of an electrical system in response to a selection signal in such a way that primarily active power or primarily reactive power is fed into the energy transmission system when the maximum current value is reached.

摘要： A method for controlling a converter of a wind energy installation. The converter is connected to the rotor of a doubly-fed asynchronous generator in order to feed 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 current output from at least one of the inverters to the doubly-fed asynchronous generator and/or to the electrical grid. The method includes detecting a change in output real power, determining whether the detected change satisfies a predefined condition, and changing a nominal value of reactive power to be output in an opposite sense to a change in real power at the grid-side inverter and in a same sense as the generator-side inverter when the predefined condition is satisfied.

摘要： An electricity generating installation is connected to an electricity distribution network and feeds electrical power into the network via a converter. After detecting a network fault, a stabilization regulator in the installation is activated. The stabilization regulator regulates the voltage of the electrical power as a function of a fed-back voltage signal and has a step-function response that rises over time. After a predetermined time period has elapsed since the activation of the stabilization regulator, the reactive current feed is increased beyond a limit which is provided for normal operation if the network has not stabilized. Accordingly, a converter-fed electricity generating installation, such as a wind energy installation, can help stabilize an electricity distribution network after a network fault.
