Abstract
The present invention relates to methods, apparatus and computer program products for coordinating the control of a floating wind turbine (101) between a wind turbine controller (111) and a platform controller (110). One or more wind turbine control systems and/or one or more platform control systems may be altered based on 102 said coordinated control of said floating wind turbine (101).
Claims35
A method comprising:
- coordinating control of a floating wind turbine between a wind turbine controller and a platform controller;
- and
- altering one or more wind turbine control systems and/or one or more platform control systems based on said coordinated control of said floating wind turbine.
A floating wind turbine comprising:
- a wind turbine controller and a platform controller wherein control is coordinated between said wind turbine controller and said platform controller;
- and
- means adapted to alter one or more wind turbine control systems and/or one or more platform control systems based on said coordinated control.
A computer program product comprising computer readable executable code for:
- coordinating control of a floating wind turbine between a wind turbine controller and a platform controller;
- and
- altering one or more wind turbine control systems and/or one or more platform control systems based on said coordinated control of said floating wind turbine.
A method comprising:
- receiving at a wind turbine controller data corresponding to a wind speed and wind direction measurement;
- coordinating control of a floating wind turbine by transmitting said data corresponding to said wind speed and wind direction to a platform controller;
- and
- altering a ballast system of a platform of said floating wind turbine by said platform controller based on said received data corresponding to said wind speed and wind direction.
A method comprising:
- receiving at a wind turbine controller data corresponding to a yaw error value;
- coordinating control of a floating wind turbine by transmitting said data corresponding to said yaw error value to a platform controller;
- and
- altering a ballast system of a platform of said floating wind turbine by said platform controller based on said received data corresponding to said yaw error value.
A method comprising:
- receiving at a platform controller data relating to metocean conditions affecting a floating wind turbine;
- coordinating control of said floating wind turbine by transmitting said data corresponding to said metocean conditions to a wind turbine controller;
- and
- setting by said wind turbine controller a lower thrust limit based on at least said received data corresponding to said metocean conditions.
A method comprising:
- receiving at a platform controller data relating to tilt and roll angles of a floating wind turbine;
- coordinating control of said floating wind turbine by transmitting said data corresponding to said tilt and roll angles to a wind turbine controller;
- and
- setting by said wind turbine controller a lower thrust limit based on at least said received data corresponding to said tilt and roll angles.
A wind turbine controller comprising:
- an input/output adapted to coordinate control of a floating wind turbine with a platform controller;
- and
- a processor adapted to alter one or more wind turbine control systems based on said coordinated control of said floating wind turbine.
A platform controller comprising:
- an input/output adapted to coordinate control of a floating wind turbine with a wind turbine controller;
- and
- a processor adapted to alter one or more platform control systems based on said coordinated control of said floating wind turbine.
