Abstract
A radar system for a wind turbine is provided. The radar system comprises a first radar unit (42) and a control unit (41) arranged to receive an output from the radar unit, the control unit comprising a central processing unit. The central processing unit is configured to perform a first function of determining at least one property of aircraft within a monitoring zone in the vicinity of the wind turbine and controlling a warning device to output a warning signal to detected aircraft based on the determined property; and perform a second function of determining at least one parameter of prevailing weather in the vicinity of the wind turbine. A corresponding method is also provided.
Claims22
A radar system for a wind turbine comprising a plurality of wind turbine blades, the radar system comprising:
- a first radar unit and a control unit arranged to receive an output from the radar unit, wherein the control unit is coupled to a wind turbine pitch control system, the control unit comprising a central processing unit configured to:
- perform a first function of:
- determining at least one property of a detected aircraft within a monitoring zone of the wind turbine based on the output of the first radar unit, controlling a warning device to output a warning signal to the detected aircraft based on the determined property, and controlling the wind turbine pitch control system to control the pitch of the wind turbine blades based on the determined property of the detected aircraft;
- and
- perform a second function of determining at least one parameter of prevailing weather in the monitoring zone of the wind turbine based on the output of the first radar unit.
A method of operating a radar system of a wind turbine comprising a plurality of wind turbine blades, the method comprising:
- providing a first radar unit and a control unit arranged to receive an output from the radar unit, the control unit comprising a central processing unit, and wherein the control unit is coupled to a wind turbine pitch control system;
- determining at least one property of a detected aircraft within a monitoring zone of the wind turbine based on the output of the first radar unit;
- controlling a warning device to output a warning signal to the detected aircraft based on the determined property;
- controlling the wind turbine pitch control system to control the pitch of the wind turbine blades based on the determined property of the detected aircraft;
- and
- determining at least one parameter of prevailing weather in the vicinity monitoring zone of the wind turbine using the output of the first radar unit.
