1. A system for assembling components of a wind turbine comprising:
a motion compensation mechanism, wherein the motion compensation mechanism comprises:
a first connection interface for connection with a first component of the wind turbine moved by a crane;
a second connection interface for connection with a second component of the wind turbine;
a tension element connecting the first connection interface and the second connection interface; and
a tension device including a force sensor for keeping the tension element under constant tension as the first component and the second component move relative to each other,
wherein the motion compensation mechanism allows a movement of the first component relative to the second component as the first component and the second component are moved relative to each other on a given trajectory,
wherein the tension device is used to provide a tension force on the tension element,
wherein the tension force is dynamically adjusted during assembly of the first component and the second component in response to force pulling at the tension device based on measurements from the force sensor to dynamically respond to movement of the first component and the second component such that when a second force pulling on the tension element is below a threshold the tension force provided by the tension device is dynamically adjusted to be increased, and such that when the second force pulling on the tension element is above the threshold the tension force provided by the tension device is dynamically adjusted to be decreased, and
wherein the tension device automatically applies a high predetermined force on the tension element that blocks a movement of the first component back and forth on the given trajectory in response to a signal provided by a contact sensor.
