摘要： A wind farm in which electrical power produced in the wind farm is transported via a wind-farm-internal network to a substation. Upon being transferred to an external network, the electrical power is transformed to a voltage which is higher by a selectable step-up ratio than the voltage in the wind-farm-internal network. The electrical load level on a wind energy installation in the wind farm is determined, and the step-up ratio is adjusted as a function of the electrical load level. Accordingly, it is possible to influence the voltage in the wind-farm-internal network such that the wind energy installations are subject to a lower electrical load level.

摘要： A wind park and operating method thereof. The 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 for operating at least one wind turbine with a rotor and an electric generator coupled to the rotor for delivering electrical power into an energy distribution system with the aid of a control device ensures that the wind turbine operates within its operating range. The wind turbine is controlled in response to the change of a system operating parameter and for a period of time, in such a manner that a higher power is fed into the system than belongs to the operating range of the steady-state operation. The same conditions also apply to a method for providing control power or primary control power for an electric energy generator and distributor system to which a multiplicity of power stations including wind turbines is connected, and to a wind turbine.

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.

摘要： A wind energy installation can include a generator which is driven by a rotor and generates electrical power in a multiphase manner for feeding into a network, a converter which is connected to the generator and to the network, and a control system which interacts with the converter and includes a negative sequence system regulation mechanism. The negative sequence system regulation mechanism can include a phase control module configured to determine an electrical variable of the negative sequence system according to the phase. Accordingly, an available current can be provided according to the operating situation for active power or idle power in the negative sequence system regulation mechanism. The negative sequence system regulation mechanism can thus help stabilize the network in the event of asymmetrical network conditions. Also, this relates to a correspondingly equipped wind park and an operating method.

摘要： A system for a wind energy installation. The wind energy installation feeds electrical power into a power supply system. A phase control device can include a power supply system fault detector, a phase angle detector, and a signal processing module. When a power supply system fault is detected, a phase error signal can be determined. A preset angle signal can be determined based on the phase error signal. The preset angle signal can be provided to a converter which can emit electrical power having a phase angle corresponding to the preset angle signal into the power supply system. Accordingly, an undesirable sudden surge in power output resulting from a phase change occurring at the end of the power supply system disturbance can be avoided.

摘要： A method is employed for operating a wind turbine. Electrical energy is produced by means of a generator and is fed into an electrical power network. The electrical energy is fed to the secondary side of a transformer at a low voltage and is output on the primary side of the transformer at a higher voltage. The potential on the primary side of the transformer is undefined. In the method, a measured value of the voltage between the primary side of the transformer and the earth potential is first recorded. The measured value is compared with a predefined limit value. The electrical energy produced by the generator is changed if the measured value exceeds the limit value. A wind turbine is designed to carry out the method. Faults in the medium voltage network can be reacted to without an additional star point on the primary side of the transformer being required.
