The present invention relates to a vertical axis wind turbine equipped with a high-temperature superconducting generator having a batch impregnation cooling structure.

The vertical axis wind turbine is configured to allow the superconducting generator and accessory devices (a cooling system, a power conversion system, etc.) to be located under a turbine tower, whereas allowing only a rotary body with vertical blades to be located on the upper portion of the turbine tower, unlike a conventional horizontal axis wind turbine, thereby remarkably reducing a top-head weight of the wind turbine, greatly decreasing installation and maintenance costs, removing technical difficulties in large scale construction, and allowing a center of weight to move to a portion under the turbine tower so that if the vertical axis wind turbine is applied for floating offshore wind power generation, it advantageously ensures the miniaturization of a floating body and the stability of a floating posture.

The wind turbine rotor blade also comprises at least two air guide sections and at least one heat exchanger for conveying heat from one air guide section to another air guide section.

Wind turbine ice protection control systems and methods for controlling ice protection measures at a wind turbine are provided. The ice protection control system operates in multiple locations: the first being at least one remote wind turbine site and the second at least one offsite control office location. The ice protection control system includes sensors on at least one wind turbine at least one remote site for sensing internal and external environmental conditions and/or wind turbine outputs. The sensors output data which is received by a network at the wind turbine and then sent to a second network at an offsite location where it is analyzed to determine actions to be taken. In this way, multiple wind turbines at multiple wind turbine remote sites can be controlled by a single control system. Systems and methods for creating, retrieving, and storing sensor data within the ice protection control systems are also discussed.

A control method and associated system provide for thermal management of cables within a structure of a wind turbine. An airflow is established through the structure, the airflow moving along and around the cables within the structure to remove heat generated in the cables via heat transfer from a core of the cables through a surrounding insulation layer of the cables. Ambient temperature and a volumetric flow rate of the airflow adjacent the cables is measure. Based on the flow rate and the ambient temperature, a threshold current capacity limit for the cables is determined and used as a control factor for increasing power production of the wind turbine within thermal limits of the cables.
