Problems solved by technology

The mechanical structure of the existing wind turbines is mostly rotor type. At present, the technology of each 2-3MW is mature. Considering the stable electric energy output, most of the existing wind turbines use a large number of batteries converted into chemical energy. The life of these battery packs is also expected, waste batteries will lead to unfriendly environment, its efficiency and sustainable development can be imagined

Embodiment Construction

[0018] The jet 3 is located at the end of the wind turbine blade ( figure 1 ), the casing 9 of the jet and the blades of the generator are carbon fiber reinforced skeleton and FRP integrated structure or assembled structure ( Figure 4 ), made of polymer materials. The jet's power adopts (DC, AC) variable frequency speed motor 8 or DC motor. The power supply structure, due to the wind turbine changing direction and the continuous rotation of the blades, the power used by the jet can be supplied to the motor 8 of the jet through the horizontal commutator 10 and the vertical commutator 11 and the wires, and the horizontal conversion The commutator 10 is arranged on the rotator of the wind turbine, and the vertical commutator 11 is arranged on the main shaft of the blade. The two groups of commutators are both ring-type brush power transmission structures ( Figure 5 ). Jet 3 can have two types: single-blade and double-blade ( image 3 The center right is a single-blade machine a...

Abstract

The invention relates to a method for mounting a jet-propelled wind driven generator, wherein a jet device is arranged on the tail end of each rotating blade of the wind driven generator. The jet device can use a counter force to accelerate or slow down each rotating blade by being vertical to the rotating blade terminal with a speed capable of outputting a back-swinging speed as same as a linear speed of the rotating blade or plus / minus 20 degrees. The counter force of the jet device can forwards or backwards compensate the rotating speed of the wind driven generator. The jet device is an axial flow fan and other airflow or airflow breaking device. The invention can promote the efficiency of the wind driven generator, automatically adjust the jet amount and the rotating speed of the jet device through a rotating speed sensor according to a preset rotating speed of the generator, maintain the rotating speed of the generator as the preset rotating speed, ensure the stable rotating speed of the generator, and generate a three-phase high-voltage current so as to directly supply power for net play.

Description

Technical field [0001] The invention relates to a wind power generator, in particular to a wind power generator with a stable output speed. Background technique [0002] Under the action of the wind, the wind generator rotates, and the strength of the wind determines the speed of the wind generator. The main elements of power generation and grid connection are phase sequence, voltage and frequency, all of which are indispensable. The reason why wind turbines cannot become the mainstream power source immediately connected to the Internet is because the speed of wind turbines cannot be stabilized, the frequency is unstable, and the three-phase alternating current generators or synchronous generators with excitation current cannot be used. Permanent magnet generators or dual-feedback generators. The output power of these types of generators is not 50 Hz AC and cannot be directly connected to the Internet. It can only be converted into DC power through mechanical energy, or even che...
