Abstract
A method of determining at least one of a rotational angle position and a rotational speed of a rotating element of a drive train includes arranging at least two sensors in an offset manner in a circumferential direction of the rotating element, recording a measured value indicative of a characteristic of a rotation of the rotating element with each sensor, and determining at least one of a rotational angle position and a rotational speed with reference to the measured values and a distance between the at least two sensors in the circumferential direction.

A method of improving operation of a drive train, comprising:
- measuring, with each of a first sensor and a second sensor, a respective first measured value and a second measured value indicative of a characteristic of a rotation of a rotating element of the drive train, the first and second sensors being offset relative to one another in a circumferential direction of the rotating element;
- determining at least one of a rotational angle position and rotational speed of the rotating element by compensating for at least one of a radial movement and a tangential movement of the rotating element relative to a nominal axis of the rotating element based on the first measured value, the second measured value, and a distance between the first and second sensors in the circumferential direction;
- and
- damping vibrations on the drive train on the basis of the determined at least one of the rotational angle position and rotational speed of the rotating element.
An energy generation plant, comprising:
- a drive train including a rotating element having a nominal axis;
- a first sensor configured to measure a first measured value of the rotating element;
- a second sensor offset relative to the first sensor by a distance in a circumferential direction of the rotating element, the second sensor configured to measure a second measured value of the rotating element;
- and
- a computing device configured to receive the first and second measured values and determine at least one of a rotational angle and a rotational speed of the rotating element by compensating for at least one of a radial movement and a tangential movement of the rotating element relative to the nominal axis based on the first measured value, the second measured value, and the distance;
- and
- wherein the computing device is further configured to regulate torque and pitch of the energy generation based on the determined at least one of the rotational angle position and rotational speed of the rotating element.
