Common circular tower wind turbines are typically 120 to 140 meters tall, but are prone to resonance. The current tallest is the 160m pre-stressed steel tube wind turbine tower, which improves the safety and service life of the tower. The four corners of the frame-type wind turbine tower have stronger bearing capacity through the lower tower body, which can effectively avoid resonance. In the future, it can continue to rise to 180m or even 200m, which will better obtain wind resources and improve the efficiency of power generation. Additional information: A wind turbine is an electrical device that converts wind energy into mechanical work, drives the rotation of the rotor, and ultimately produces alternating current. Wind turbines generally consist of a wind turbine, a generator (including devices), a direction regulatorn (tail), a tower, a speed-limiting safety mechanism and an energy storage device. The operating principle of wind turbines is relatively simple. The wind wheel rotates under the influence of the wind, and the wind converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates under the drive of the wind wheel shaft to produce electricity. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a heat fluid. work.
