Design of transportable wind turbine (HAWT) with self - adjusting system

In the paper authors presented an innovative design of the transportable horizontal axis wind turbine with a capacity of 3.5 kW, which can be use generally in hard field conditions. Simple, lightweight, and inexpensive design gives wide possibilities of its effective use. The self-adjusting system with the turbine protection against exceeding the speed limit ensures practically maintenance-free operation. The self-adjusting system provides continuous setting of the wind turbine on the wind direction, and at the same time protects of the main rotor HAWT (Horizontal Axis Wind Turbine) against excessive speed in strong winds. This solution can replace the most commonly used solution like the directional rudder or the auxiliary wind motor, which usually requires using the generator rotor brake, because works without negative impact to the wind turbine (a low gyroscopic torque) and does not require additional electric power from outside. The use of ballast in exchange for the existing installation of the mast support structure to the foundation makes the project of the wind turbine proposed by the authors more transportable. The design a wind turbine with low power, which can be easily assembled, leave to exploitation, disassembled and then transported to the new place of work without anchoring to the foundation which are permanently linked with a ground become the main goal of the work.
