Abstract
A method of operating a wind turbine during a service, wherein the wind turbine comprises at least one rotor-nacelle assembly, the or each rotor-nacelle assembly comprising a rotor; the method comprising: detecting that a service is to be or is being carried out on the wind turbine; and, on detecting that a service is to be or is being carried out on the wind turbine, reducing an operating level of the or each rotor-nacelle assembly.
Claims18
A method of operating a wind turbine during a service, wherein the wind turbine comprises a rotor-nacelle assembly comprising a rotor, the method comprising:
- detecting, based on data from one or more sensors embedded within a wind turbine, that a service is to be or is being carried out on the rotor-nacelle assembly of the wind turbine by detecting a selection of the rotor-nacelle assembly for service, and detecting a presence of personnel in a vicinity of the rotor-nacelle assembly;
- and
- on detecting that the service is to be or is being carried out on the rotor-nacelle assembly:
- reducing an operating level of the rotor-nacelle assembly;
- and
- reducing an overspeed threshold or an overpower threshold of the rotor by an amount greater than an amount by which the operating level of the rotor-nacelle assembly is reduced.
A controller for a wind turbine control system comprising a processor and a memory module, wherein the memory module comprises a set of program code instructions which when executed by the processor configures the processor to:
- (a) detect, based on data from one or more sensors embedded within a wind turbine, that a service is to be or is being carried out on a rotor-nacelle assembly of the wind turbine by:
- (i) detecting a selection of the rotor-nacelle assembly for service;
- and
- (ii) detecting a presence of personnel in a vicinity of the rotor-nacelle assembly;
- and
- (b) based on the detection that a service is to be or being carried out:
- (i) reduce an operating level of the rotor-nacelle assembly;
- and
- (ii) reduce an overspeed threshold or an overpower threshold of a rotor of the rotor-nacelle assembly by an amount greater than an amount by which the operating level of the rotor-nacelle assembly is reduced.
A computer program product downloadable from a communication network and/or stored on a machine readable medium comprising program code instructions which, when executed by one or more processors, configure the one or more processors to:
- (a) detect, based on data from one or more sensors embedded within a wind turbine, that a service is to be or is being carried out on a rotor-nacelle assembly of the wind turbine by:
- (i) detecting a selection of the rotor-nacelle assembly for service;
- and
- (ii) detecting a presence of personnel in a vicinity of the rotor-nacelle assembly;
- and
- (b) based on the detection that a service is to be or being carried out:
- (i) reduce an operating level of the rotor-nacelle assembly;
- and
- (ii) reduce an overspeed threshold or an overpower threshold of a rotor of the rotor-nacelle assembly by an amount greater than an amount by which the operating level of the rotor-nacelle assembly is reduced.
A wind turbine, comprising:
- a tower;
- a rotor-nacelle assembly comprising a nacelle and a rotor extending from the nacelle;
- a plurality of blades disposed on the rotor;
- a wind turbine control system comprising a processor and a memory module, wherein the memory module comprises a set of program code instructions which when executed by the processor configures the processor to:
- (a) detect, based on data from one or more sensors embedded within a wind turbine, that a service is to be or is being carried out on the rotor-nacelle assembly by:
- (i) detecting a selection of the rotor-nacelle assembly for service;
- and
- (ii) detecting a presence of personnel in a vicinity of the rotor-nacelle assembly;
- and
- (b) based on the detection that a service is to be or being carried out:
- (i) reduce an operating level of the rotor-nacelle assembly;
- and
- (ii) reduce an overspeed threshold or an overpower threshold of the rotor by an amount greater than an amount by which the operating level of the rotor-nacelle assembly is reduced.
