Abstract
A wind turbine system comprising: a wind turbine; and a monitoring system, wherein the wind turbine comprises: a tower; an arm extending from the tower, a rotor-nacelle assembly (RNA) carried by the arm; and a Global Navigation Satellite System (GNSS) sensor carried by the arm or the RNA. The monitoring system is configured to receive position data from the GNSS sensor and obtain a moment or force measurement on the basis of the position data.
Claims25
A wind turbine system comprising:
- a wind turbine including:
- a tower,
- an arm extending from the tower,
- a rotor-nacelle assembly (RNA) carried by the arm, and
- a Global Navigation Satellite System (GNSS) sensor carried by the arm or the RNA;
- and
- a monitoring system configured to;
- receive position data from the GNSS sensor, and
- determine a moment or force measurement on the basis of the position data.
A method of monitoring a wind turbine, the wind turbine comprising a tower;
- an arm extending from the tower;
- a rotor-nacelle assembly (RNA) carried by the arm;
- and
- a Global Navigation Satellite System (GNSS) sensor carried by the arm or the RNA, the method comprising:
- generating position data with the GNSS sensor;
- and
- obtaining a moment or force measurement on the basis of the position data.
A method of monitoring a multi-rotor wind turbine, the multi-rotor wind turbine comprising:
- a tower, the tower comprising a tower body and a yaw structure which is rotatably mounted to the tower body;
- a first arm extending from the yaw structure, a first rotor-nacelle assembly (RNA) carried by the first arm;
- a first Global Navigation Satellite System (GNSS) sensor carried by the first arm or the first RNA;
- a second arm extending from the yaw structure;
- a second rotor-nacelle assembly (RNA) carried by the second arm;
- and a second Global Navigation Satellite System (GNSS) sensor carried by the second arm or the second RNA, the method comprising:
- generating first position data with the first GNSS sensor;
- generating second position data with the second GNSS sensor;
- and
- obtaining a yaw moment measurement on the basis of the first position data and the second position data, wherein the yaw moment measurement indicates a net yaw moment applied to the yaw structure by the first and second arms.
