Abstract
A heating deicing system for a blade and a control method thereof, a blade and a wind turbine are provided according to the present disclosure. The heating deicing system for the blade includes an isolating device, which is arranged in a blade cavity and divides a part of the blade cavity close to a leading edge of the blade into multiple sub-cavities sequentially distributed along a length direction of the blade, and each of the sub-cavities is provided with a heating device. The heating deicing system for the blade includes a controller, which is configured to separately control opening and closing of each set of multiple sets of heating devices in each sub-cavity to heat the multiple sub-cavities in response to a blade deicing instruction.
Claims20
A heating deicing system for a blade, comprising:
- an isolating device arranged in a blade cavity and dividing a part of the blade cavity close to a leading edge of the blade into a plurality of sub-cavities sequentially distributed along a length direction of the blade;
- a heating device set arranged in the plurality of sub-cavities;
- and
- a controller configured to separately control opening and closing of the heating device set in the plurality of sub-cavities to heat the plurality of sub-cavities, respectively, in response to a blade deicing instruction,
- wherein the heating device set comprises at least a first heating device and a second heating device for each sub-cavity, and the controller is further configured to separately control opening and closing of the first and second heating devices in the sub-cavity.
A blade, comprising:
- a blade cavity;
- an isolating device arranged in the blade cavity and dividing a part of the blade cavity close to a leading edge of the blade into a plurality of sub-cavities sequentially distributed along a length direction of the blade;
- and
- a heating device set arranged in the plurality of sub-cavities, comprising at least a first heating device and a second heating device for each sub-cavity,
- wherein opening and closing of the heating device set in the plurality of sub-cavities are controlled separately by a controller to heat the plurality of sub-cavities, respectively, in response to a blade deicing instruction, and
- wherein the controller is further configured to separately control opening and closing of the first and second heating devices in the sub-cavity.
A wind turbine comprising:
- a blade, comprising:
- a blade cavity;
- an isolating device arranged in the blade cavity and dividing a part of the blade cavity close to a leading edge of the blade into a plurality of sub-cavities sequentially distributed along a length direction of the blade;
- and
- a heating device set arranged in the plurality of sub-cavities;
- and
- a master programmable logic controller (PLC) configured to separately control opening and closing of the heating device set in the plurality of sub-cavities to heat the plurality of sub-cavities, respectively, in response to a blade deicing instruction,
- wherein the heating device set comprises at least a first heating device and a second heating device for each sub-cavity, and the master PLC is further configured to separately control opening and closing of the first and second heating devices in the sub-cavity.
