Abstract
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 apart 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.
Claims16
A method of controlling a wind park comprising one or more wind turbines, one or more airborne wind energy systems, and a computer system, each of the one or more wind turbines comprising a tower, at least one nacelle mounted on the tower, and a rotor coupled to the at least one nacelle and rotatable about a rotation axis for generating electrical energy for a power grid, each of the one or more airborne wind energy systems comprising an airborne unit, a base, and a cable connecting the airborne unit to the base, and the computer system controlling at least one of the one or more wind turbines and at least one of the one or more airborne wind energy systems based on a set of control parameters, the method comprising the steps of:
- defining, for at least one of the one or more airborne wind energy systems, a first zone and a second zone such that a risk of a collision between a part of the at least one of the one or more airborne wind energy systems and a part of the at least one of the one or more wind turbines is higher when the airborne unit of the at least one of the one or more airborne wind energy systems is in the second zone than when the airborne unit of the at least one of the one or more airborne wind energy systems is in the first zone,
- operating the airborne unit of the at least one of the one or more airborne wind energy systems in each of the first zone and the second zone,
- determining a position of the airborne unit of the at least one of the one or more airborne wind energy systems,
- in response to the airborne unit being in the first zone, controlling the at least one of the one or more wind turbines and the at least one of the one or more airborne wind energy systems based on a first set of control parameters to continue operating the airborne unit of the at least one of the one or more airborne wind energy systems in the first zone while the rotor of the one or more wind turbines rotates, and
- in response to the airborne unit being in the second zone, controlling the at least one of the one or more wind turbines and the at least one of the one or more airborne wind energy systems based on a second set of control parameters that bring the position of the airborne unit of the at least one of the one or more airborne wind energy systems into the first zone.
A wind park, comprising:
- one or more wind turbines each comprising a tower, at least one nacelle mounted on the tower, and a rotor coupled to the at least one nacelle and rotatable about a rotation axis for generating electrical energy for a power grid, one or more airborne wind energy systems each comprising an airborne unit, a base, and a cable connecting the airborne unit to the base,
- an electronic data storage that stores a data set for at least one of the one or more airborne wind energy systems, the data set comprising at least a first zone data set defining a first zone, and a second zone data set defining a second zone in which a collision between at least one of the one or more wind turbines and the at least one of the one or more airborne wind energy systems is higher than in the first zone,
- an electronic controller operable on data in the data storage, and
- a global positioning system configured for determining a position of the airborne unit of the at least one of the one or more airborne wind energy systems,
- the electronic controller being configured to process the position and the first zone data set and the second zone data set, and based thereon to:
- determine if the airborne unit of the at least one of the one or more airborne wind energy systems is in the first zone or in the second zone,
- in response to the airborne unit being in the first zone, control the at least one of the one or more wind turbines and the at least one of the one or more airborne wind energy systems based on a first set of control parameters to continue operating the airborne unit of the at least one of the one or more airborne wind energy systems in the first zone while the rotor of the one or more wind turbines rotates, and
- in response to the airborne unit being in the second zone, control the at least one of the one or more wind turbines and the at least one of the one or more airborne wind energy systems based on a second set of control parameters that bring the position of the airborne unit of the at least one of the one or more airborne wind energy systems into the first zone.
