Accompanying drawing 1 is a vertical-axis generators group schematic representation of the present invention
Embodiment
Embodiment 1, vertical-axis generators group mode of execution:
Pylon 1 connects cabinet 2, and the cabinet upper end connects main shaft 6, and main shaft connects the main wind wing 7 and the secondary wind wing 9.Connect 1 main generator 3 or 1 subsidiary generator 301 or 2 subsidiary generators or 3 subsidiary generators through gearbox 5 in the cabinet of main shaft lower end, interconnect with magnetic clutch 4 between the major and minor generator.Cable 11,13, intelligent control system 12 and energy storage voltage stabilizing commutation system 14 are set in the pylon, constitute the vertical shaft overall structure.
What aforementioned main shaft 6 was connected is 4 subsidiary generators of 1 main generator, is interconnective through 3 magnetic clutchs 4 between the generator.
Realize the measure of intelligent gradient: air velocity transducer 15 transmits signals, and instruction only drives main generator 3 generatings under conventional wind speed, when wind speed strengthens through cable 11 by intelligent control system 12 1 subsidiary generator that superposes step by step; Or 2 subsidiary generators; Or 3 subsidiary generators.When reducing, wind speed automaticallyes switch.
High-quality measure is stablized in realization: be to network after cable 13 connects sodium-sulphur battery, inverter, rectifier, energy storage voltage stabilizing commutation system 14 at generator 3.
Connect the secondary wind wing 9 of arc of 18 uniform arc main wind wings 7 and 18 inclinations around on the axis body of main shaft 6 through support 8 Vertical direction, this major and minor wind wing quantity is identical.The main wind wing and the secondary wind wing are formed one deck, can superpose on the main shaft 6 2～4 layers.
Described main wind wing individuality highly is 5 meters, 1 meter of the individual height of the secondary wind wing, and main wind wing 7 contains 15 meters of support 8 planar development radiuses.
Another embodiment: the main shaft 6 vertical connection wind wings 7 and level are connected cabinet 2 one ends, connect gearbox 5 thereafter, connect a main generator 3 and 3 subsidiary generators 301 again, connect with magnetic clutch 4 between the subsidiary generator.2 times connection pylons 1 of cabinet are provided with cable 11,13, intelligent control system 12, energy storage voltage stabilizing commutation system 14 in the pylon 1, constitute the horizontal axis overall structure.
Because generator is sent out the finiteness of designed capacity, the wind-driven generator that therefore a generator is housed can only work in certain wind speed range, crosses weak in the middle of this and strong excessively wind all can not be used for generating.If but a generator is decomposed into several, and wind wheel is big or small constant, and this wind wheel is will inevitably be because of the consideration that reduces and design of load strong to drag after the decomposition one or several small generators and run under the very low wind friction velocity and normal power generation.If increase some the generators that are linked in sequence with wind wheel more as required as the wind wheel load under the various high wind conditions after this, because load is huge and adjustable, that wind wheel does not just need to adjust propeller pitch angle to adjust stress again, even do not need brake, but directly the various huge wind energy that occurs is converted into the kinetic energy of wind wheel to greatest extent to be used for driving the generator combination generating.
