A system for monitoring a plurality of wind turbines can include a turbine categorizer, executing on one or more computing platforms that categorizes each of a plurality of wind turbines as being damaged or undamaged to form a list of potentially damaged wind turbines. The system can also include a damage evaluator executing on the one or more computing platforms that predicts a damage type and a stage for each wind turbine in the list of potentially damaged wind turbines. The system can further include an impact engine executing on the one or more computing platforms that assigns a repair window and a priority for each wind turbine in the list of potentially damaged wind turbines based on a respective predicted damage type and stage.

An energy farm comprising an electrical grid through which power generated by the devices in the farm may be combined and transmitted. The electrical grid is formed through the electrical interconnection of devices in a farm through electrical connections that remain, in whole or at least in part, adjacent to the surface of the body of water on which the devices float. A plurality of converters of the network have no direct or immediate electrical interface with a subsea power cable (i.e. a cable on or under the seafloor), but instead transmit electricity to other converters in a daisy-chained fashion.

According to the invention, the control system consists of one or more global controllers configured to receive state data from the tower structures and tendons, via sensors and control an operating state of the wind generators correspondingly in a calculation method for avoiding load peaks and/or avoiding resonances. In a preferred embodiment, a local controller is configured to also process status data of the sensors from a near field of a building around the respective local controller.

Embodiments of the present disclosure include a data processing and control augmentation system capable of identifying overloading of one or more wind turbine assemblies and providing information to a wind farm controller to reduce a power output of each overloaded turbine. The augmentation system thus reduces the power output of each overloaded turbine and, in turn, reduces loads applied to the wind turbine assembly, such as for a period of time until conditions favorably change. A described analysis of the present disclosure is able to utilize several incoming data streams from sensors so arranged to measure wind effects on blades to calculate and compare cyclic loads to threshold limits to o keep the loads within design limits. The control strategy reduces premature failure of components within the wind turbine assembly, and can be applied across an entire wind farm, even with only a subset of wind turbine assemblies being retrofitted.

A wind park with wind turbines and airborne wind energy systems where a first zone and a second zone is defined for at least one of the airborne wind energy systems such that the risk of collision between a part of that airborne wind energy systems and a part of one of the wind turbines is higher when the airborne unit of that airborne wind energy system is in the second zone than when it is in the first zone, and different control parameters are applied to the control of at least one of the wind turbine and the airborne wind energy system depending on the position of the airborne unit relative to the defined zones.

A system and method are provided for operating and maintaining a wind turbine. Accordingly, a plurality of data inputs are received. The plurality of data inputs represent a plurality of monitored attributes of a component of the wind turbine. A consolidated risk index for the component is determined using the plurality of monitored attributes, and a range of potential risk indices is forecasted. A remaining-useful-life distribution is determined based on the damage potential and an end-of-life damage threshold. The wind turbine is shut down or idled if the remaining-useful-life distribution is below a shutdown threshold.

The invention relates to a method for measuring and correcting the angle of attack in a wind turbine farm (11), by which means the yield of each wind turbine (11) of the wind farm is measured initially in order to be able to define a model wind turbine which will be the one which generates the maximum power. The creation of coordinate axes for each blade (15) of the wind turbine (10) allows the angle of attack of the blades (15) of said model wind turbine (10) to be calculated and a reference value to be defined in order to copy same to each blade (15) of the rest of the wind turbines (11), in such a way that the optimum power ratio is obtained for each wind turbine of the wind farm.

A method for retrofitting a wind turbine foundation is provided. The foundation comprises a first substantially elongated pile (31) in the ground. The method further comprises: arranging a lower end of an elongated channel (41) of a second substantially elongated pile (40) around the first pile (31), wherein the elongated channel (41) extends substantially along a longitudinal direction of the second pile (40), wherein the channel (41) is configured to receive at least a portion of the first pile. The method further comprises lowering the second pile (40) such that the elongated channel (41) surrounds at least a portion of the first pile (31). Finally, the second pile (40) is driven into the ground (35).

In some embodiments, each of the number of modules is positioned no closer than approximately six turbine diameters and no further than approximately fifteen turbine diameters from each another.

A wind turbine comprises a nacelle, a drive shaft extending from the nacelle along a shaft axis, a plurality of turbine blades coupled to the drive shaft and extending radially relative to the shaft axis, and a first static airfoil structure coupled to the wind turbine to influence airflow exiting the plurality of turbine blades. A method of increasing wind turbine efficiency in a wind farm comprises positioning a first wind turbine having a first plurality of turbine blades at least partially upstream of a second wind turbine having a second plurality of turbine blades, producing a wake field of exit air behind the first plurality of turbine blades, directing air outside of the wake field into the wake field to increase speed of airflow in the wake field, and directing the airflow into the second plurality of turbine blades of the second wind turbine.
