Control system, method and program, and floating wind turbine generator provided therewith |
摘要 |
The control system of this floating wind turbine generator is a control system of a floating wind turbine generator in which the control system controls a pitch angle control section by a pitch angle instruction value calculated on the basis of signals detected by a second sensor detecting a relative angle between a nacelle and a tower and a third sensor detecting a yaw angle from a reference position of the tower so that a signal detected by a first sensor detecting wind direction deviation relative to a vertical direction of a rotation plane of wind turbine blades indicates an angle within a predetermined range from the vertical direction of the rotation plane of the wind turbine blades, and controls a yaw driving device by a yaw driving instruction value calculated on the basis of the signals detected by the second sensor and the third sensor. |

1. A control system of a floating wind turbine generator, the floating wind turbine generator comprising: a yaw driving device adapted to cause a nacelle to perform turning in a yaw direction relative to a tower provided with the nacelle at the upper end thereof, the nacelle being provided with a rotor head that rotates by a plurality of wind turbine blades receiving wind power; and a pitch angle control section adapted to drive the wind turbine blades to control a pitch angle thereof, wherein
the control system controls the pitch angle control section according to a pitch angle instruction value calculated on the basis of a signal detected by a second sensor for detecting a relative angle between the nacelle and the tower and a signal detected by a third sensor for detecting a yaw angle from a reference position of the tower so as to keep a signal indicating an angle within a predetermined range relative to a vertical direction of a rotation plane of the wind turbine blades, the signal being detected by a first sensor for detecting a wind direction deviation relative to the vertical direction of the rotation plane of the wind turbine blades, and controls the yaw driving device according to a yaw driving instruction value calculated on the basis of the signals detected by the second sensor and the third sensor. |
