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 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： 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 wind turbine with a rotor and a generator driven by, the rotor generates electrical power and delivers it to a power system. A control unit controlling the operation of the plant includes a reactive-power control module. The control unit includes also a determining device for a safe minimum active power. Furthermore, and a limiting device for the reactive-power control module, wherein the reactive power is limited to such a measure that the safe minimum active power is still available, taking into consideration the available power. As a result, the total current generated, apart from the active current required for the safe operation of the plant, can be fed into the power system as reactive current as backup in the case of a voltage drop.
