摘要： The invention relates to wind turbines, particularly to controlling reactive power exchange between a power grid and a wind power plant. The wind power plant has a plurality of wind turbine generators each having a corresponding power converter with a converter controller. Further, the wind power plant has a power plant transformer with an on load tap changer coupled between the wind power plant and the power grid. The power plant controller is regulating the on load tap changer and is generating reactive component setpoints for the wind turbine generators, when determining a need for production of short-term reactive power due to a sudden change in reactive power measured at the point of common coupling.

摘要： A method and control arrangement are disclosed for controlling power output of a wind power plant (WPP) including a plurality of wind turbine generators (WTGs). The method includes determining that overboosting is required for the WPP to meet a power demand at the WPP, and determining, for at least a first WTG of the plurality of WTGs, a corresponding amount of overboost capacity. The method further includes generating, based on the determined amount of overboost capacity, control signals causing the first WTG to increase its power output through overboosting to thereby fulfill at least a portion of the power demand.

摘要： Aspects of the present invention relate to a method (100) for controlling a plurality of renewable energy generators (14). The method (100) comprises: determining (102) preliminary reactive power set points for the generators (14) based on a reactive power reference value; determining (104) generator-based and voltage-based reactive power limits for the generators (14); generating (106) dispatch signals for requesting reactive power from the generators based on the preliminary set point and the limits; and dispatching (108) the dispatch signals to the generators (14). The generator-based reactive power limits correspond to the reactive power capability of the generator. The voltage-based limits are determined by: determining (112) a terminal voltage of the generator; comparing (114) the determined terminal voltage to a voltage limit; and determining (116) the voltage-based reactive power limit based on the comparison.

摘要： A method for controlling a current injected to a power grid (2) from a renewable power plant (1), in response to a voltage event in the power grid (2), is disclosed. Occurrence of a voltage event in the power grid (2) is detected. At least a current at a point of common coupling (3) between the renewable power plant (1) and the power grid (2) is determined, and the determined current is provided to a power plant controller (4). The power plant controller (4) derives individual current setpoint corrections for at least some wind turbines (5) within the renewable power plant (1), based on the determined current, and dispatches each derived current setpoint correction to wind turbine controllers (6) of the corresponding wind turbines (5). The wind turbine controllers (6) control a current output of the respective wind turbines (5), based on measurements of current and/or voltage at a point of connection (8) between the wind turbine (5) and an internal grid (7) of the renewable power plant (1), and by taking the current setpoint correction dispatched from the power plant controller (4) into account.

摘要： Embodiments provide for the control of a power plant including several generators by setting a reference frame for the generators with a first and a second axis; measuring a grid demand voltage at the shared connection point; determining active and reactive currents required at the shared connection point based on the grid demand voltage and grid codes; transforming the active and reactive currents required at the shared connection point to the reference frame where the first axis defines a first current set point and the second axis defines a second current set point; and dispatching the first and second current set points to generator controllers associated with each generator. Current set points may be generated for positive/negative frames, direct quadrature frames, real/imaginary frames and may be set evenly for all generators or adjusted per generator.
