    摘要： Systems, methods, and non-transitory computer readable media including instructions for coordinated braking of a plurality of geographically-associated fluid turbines. Coordinated braking of a plurality of geographically-associated fluid turbines includes accessing memory storing information indicative of a tolerance threshold for an operating parameter associated with the plurality of geographically-associated fluid turbines; receiving information from a sensor indicative of the operating parameter for a particular fluid turbine among the plurality of geographically-associated fluid turbines; comparing the information indicative of the operating parameter for the particular fluid turbine with the tolerance threshold; determining, based on the comparison, whether the operating parameter for the particular fluid turbine deviates from the tolerance threshold; and upon a determination that the operating parameter for the particular fluid turbine deviates from the tolerance threshold, sending a braking signal to each of the geographically-associated fluid turbines to slow each of the geographically-associated fluid turbines.

    摘要： Disclosed is a wind turbine layout optimization method combining with a dispatching strategy for the wind farm. In the wind farm micro-siting stage, the installed wind turbines number and the arrangement positions are optimized. In this method, the dispatching strategy of wind turbines is considered during the layout optimization of wind turbines, and the axial induction factor of each wind turbine is introduced into the layout optimization variables. The dispatching strategy of maximizing the wind farm power generation is combined with the layout optimization of wind turbines in the construction stage of the wind farm, so that the wake effect is effectively reduced and the capacity cost is reduced, which meet the requirement of actual wind farm. A hybrid optimization algorithm is proposed in this method, with a greedy algorithm to optimize the turbine number and a particle swarm optimization (PSO) algorithm to refine the turbine layout scheme.

    摘要： A method for operating a first wind power installation comprising a rotor having a rotor blade that is adjustable with a pitch angle, which generates an electrical power and in the wake of which a second wind power installation is located in at least one wake wind direction, comprising the step of: operating the first wind power installation in a substantially wake-free normal mode with a first pitch characteristic, and operating the first wind power installation in a wake-loaded wake mode with a second pitch characteristic, wherein the first pitch characteristic represents a first profile of the pitch angle and the second pitch characteristic represents a second profile of the pitch angle as a function of the electrical power, wherein the pitch angle of the second pitch characteristic is greater than the pitch angle of the first pitch characteristic for at least one range of the electrical power. The method seeks to maximise the annual energy production of the second wind power installation while complying with constraints, such as compliance with maximum thrust coefficients or wake-influenced turbulence intensities.

    摘要： A cooperative operation optimization control method for wind turbine groups, including: dividing wind turbine groups based on a digital model and an improved Jensen wake model; performing multi-degree-of-freedom controller design on wind turbines; calculating an ultimate load of the wind turbines jointly by using two methods, and constructing a safe load constraint and a yaw angle constraint for wind turbine operation in conjunction with a safe load coefficient; establishing a collaborative optimization problem model of the wind turbine groups by taking the maximum generating power of the wind turbine groups as an optimization objective, a yaw angle of an upstream wind turbine as a decision variable, and the safe load constraint, the yaw angle constraint and a power change range of the upstream wind turbine as constraint conditions; and determining a cooperative operation optimization algorithm for the wind turbine groups, and optimizing the yaw angle of the wind turbines.

    摘要： A method for operating a wind turbine for generating a settable turbine power, where the wind turbine includes a rotor having rotor blades adjustable in their blade angle, is operable at a settable rotor speed, and is installed at an installation site at a distance to an obstacle, comprises the obstacle causing a wind disturbance, which, in dependence on current wind direction and wind velocity, can reach the wind turbine as a wind wake, and the wind turbine reducing its turbine operation by throttling down for protection against loads due to the wind wake, wherein the throttling down is controlled in dependence on the current wind direction and the current wind velocity, wherein a weather prediction is used in order to take into consideration at least one further weather property in addition to the wind direction and wind velocity, and wherein the throttling down is additionally controlled in dependence on the weather prediction, in particular on the further weather property.

    摘要： A method for controlling a first wind turbine cluster to improve wake recovery of the wind that flows through that cluster, which may therefore improve the consistency of air flow for a downstream cluster of wind turbines. The method comprises quantifying a wake effect of the first wind turbine cluster on the operational performance of a second wind turbine cluster, identifying a triggering condition based on the quantified wake effect, and, in response, controlling one or more operational parameters of the wind turbines in the first wind turbine cluster to improve the wake recovery of the first wind turbine cluster.

    摘要： Systems, methods, and non-transitory computer readable media including instructions for synchronizing a plurality of geographically-associated fluid turbines. Synchronizing a plurality of geographically-associated fluid turbines includes receiving first signals indicative of a phase of a rotational cycle of first rotating blades of a first turbine configured to generate a downstream fluid flow; receiving second signals indicative of a phase of a rotational cycle of second rotating blades of a second turbine configured to receive at least a portion of the downstream fluid flow and generate a differential power output; determining from the first and second signals that greater aggregate power output is achievable through blade phase coordination; determining a phase correction between the first and second rotating blades based on the first and second signals to achieve the greater aggregate power output; calculating coordinating signals based on the phase correction; and outputting the coordinating signals to impose the phase correction.
