Abstract
A method of operating installations (10), in particular wind energy installations (10), having a component (22) which endangers flying animals, in which the component assumes a first state which endangers animals to a greater extent and a second state which endangers animals to a lesser extent. The physical environment around the installation (10), in particular the environment around the component (22), is monitored at least in regions by a suitable detection device. The detection device produces a signal when an animal of a specific type, in particular a bat, a bird or the like, enters the monitored region, and in which case the component of the installation is moved from the state which endangers animals to a greater extent to the state which endangers animals to a lesser extent depending on the signal.
Claims22
A method for operating installations (10) having at least one component (22) which endangers flying animals, comprising the steps of:
- the component assuming a first state which endangers animals to a greater extent and a second state which endangers animals to a lesser extent,
- monitoring the physical environment around the installation (10) and around the component (22) at least in regions by means of a suitable detection device, the detection device producing a signal when a flying animal enters the monitored region,
- moving the component of the installation from the state which endangers animals to a greater extent to the state which endangers animals to a lesser extent depending on the signal and, later, moving the installation back to the state which endangers animals to a greater extent, depending on:
- a) the number of animals of a specific type detected per unit time, and/or
- b) the signal characteristic of the respectively produced signal, and/or
- c) if none of the animals of the specific type, which were triggers for the component being moved to the less dangerous state, are detected in the monitored region during a predetermined period of time.
A method for operating a wind energy installation, the wind energy installation (10) having a rotor (18), which can be driven by wind and has at least one rotor blade (22), and a generator for the purpose of converting the mechanical energy of the rotor (18) to electrical energy, comprising the steps of:
- monitoring the physical environment around the wind energy installation (10) at least in regions by means of a suitable detection device, the detection device producing a signal when a bat enters the monitored region, and
- depending on the number of the bats detected per unit time, and/or depending on the signal characteristic of the respectively produced signal, at least substantially suppressing the rotation of the rotor blade (22) of the wind energy installation (10) at least for a specific period of time or at least reducing the rotational frequency of the rotor blade (22),
- wherein the at least substantial suppression of the rotation of the rotor blade (22) or the reduction in the rotational frequency is dispensed with or canceled depending on:
- a) the number of the bats detected per unit time, and/or
- b) the signal characteristic of the respectively produced signal, and/or
- c) if, during a predetermined period of time, none of the bats, which could be triggers for suppression of the rotation or for a reduction in the frequency of rotation, are detected in the monitored region.
A wind energy installation (10) comprising:
- a rotor (18), which can be driven by wind and has at least one rotor blade (22),
- a generator for the purpose of converting the mechanical energy of the rotor (18) to electrical energy,
- a detection device for the purpose of monitoring the physical environment around the wind energy installation (10) at least in regions, the detection device producing a signal when a flying object of a specific type enters the monitored region, and
- a control/regulating device which is designed in such a way that, depending on the number of animals detected per unit time, and/or depending on the signal characteristic of the respectively produced signal, the rotation of the rotor blade (22) of the wind energy installation (10) is at least substantially suppressed at least for a specific period of time or at least the rotational frequency of the rotor blade (22) is reduced, and in which case, later, the at least substantial suppression of the rotation of the rotor blade (22) or the reduction in the rotational frequency is dispensed with or can be canceled depending on:
- a) the number of animals detected per unit time, and/or
- b) the signal characteristic of the respectively produced signal, and/or
- c) if, during a predetermined period of time, none of the animals of a specific type, which could be triggers for suppression of the rotation or for a reduction in the frequency of rotation, are detected in the monitored region.
