Abstract: A pivoting wind turbine tower assembly includes at least one wind turbine, at least one base structure, and at least one lifting mechanism. The lifting mechanism includes a mounting shaft, a pivoting arm, a counterweight, a winch, and a cable. The mounting shaft is outwardly connected to the base structure. The pivoting arm is rotatably mounted to the mounting shaft. The wind turbine is terminally mounted to a first end of the pivoting arm. The counterweight is terminally mounted to a second end of the pivoting arm. The winch is mounted offset to the counterweight as the cable is tensionably connected between the counterweight and the winch. Resultantly, the rotational direction of the winch is able to move the orientation of the pivoting arm so that the wind turbine can be configured into a lowered position and a raised position about the mounting shaft.

Abstract: An equipment for installing and dismantling of a wind turbine system including a tower, a nacelle and a blades is capable of self-climbing along the tower via upper and lower grippers moving up and down the supporting frame equipped with two booms along the tower. The two booms aren't able to turn around in horizontal plan but are able to hoist, for example, the nacelle and pivot it to the top of the tower before placing it on the positioning frame. In order to combine the nacelle to the tower, the nacelle resting on the positioning frame shall be adjusted to the location of the tower in horizontal plan before the positioning frame is lowering it to the tower.

Abstract: The present invention relates to control of a wind turbine to reduce structural loading due to vibrations of the blades along the edgewise direction. A rotor control system for actuating pitch of pitch-adjustable rotor blades of a wind turbine is disclosed. Pitch modification signals are determined based on edgewise load signals for each of the rotor blades. The edgewise load signal are coordinated transformed and input into a primary whirling controller unit to provide whirling signal components which can be used for determining the pitch modification signals.

Abstract: The present disclosure provides a method and device for simulating a dynamic digital twin model of dominant operation of a wind turbine generator assembly, by which conventional operational parameters of the wind turbine generator assembly that are acquired in real time are preprocessed to obtain steady-state operational parameters of the wind turbine generator assembly. A pneumatic subsystem-related data black box model, a transmission subsystem model, a tower subsystem model, and an electrical subsystem model are simulated individually using the steady-state operational parameters, and then combined to form a dynamic dominant-operation simulation model for simulating an operation process of the wind turbine generator assembly. Meanwhile, a dynamic deviation compensation model is constructed on the basis of the dynamic dominant-operation simulation model.
