Description

A kind of wind-driven generator
Technical field
The present invention relates to a kind of generator, particularly a kind of wind-driven generator.
Technical background
Because wind energy power is with cube variation of wind speed, so the scope that the output of the power of blower fan changes with wind speed very greatly.This characteristic of wind energy makes wind-driven generator differ thousands of times, frequency change at the generated output of incision wind speed and cut-out wind speed and reaches nearly a hundred times.
Present wind-driven generator all operates in below the rated power of design, the common corresponding rated wind speed of the rated power of wind-driven generator; When wind speed during greater than rated wind speed, the control system of blower fan makes the state variation of the wind wing so that " overflowing " part wind energy makes wind-driven generator operate under the rated power, to avoid burning out generator.At this moment the wind energy of " overflowing " is not utilized.As seen rated wind speed is designed to cut-out wind speed, Wind Power Utilization degree maximum.But the generator rating power that big rated wind speed is corresponding big makes generator resistance of start square increase, cut wind speed and improve, and the wind power generation efficient when wind speed is lower than rated wind speed reduces.
Summary of the invention
The objective of the invention is to design a kind of generator, it can produce big generator rating power, can produce the little moment of resistance again when starting, can also modulate the generating frequency by the generated output that changes generator, thereby improve wind power generation efficient and reduce the cost that constant frequency is controlled.
Purpose of the present invention can realize by adopting following design: a kind of generator, it is mainly by main shaft 1, bearing 2, endosome 3 and ectosome 4 are formed, described endosome 3 is made up of iron core 5 and armature winding 10, endosome 3 is connected with main shaft 1, described ectosome 4 is by the excitation body, driver 6, shell 7 and end casing 8 are formed, end casing 8 is connected with shell 7, the inner of end casing 8 is connected with bearing 2, the excitation body of described ectosome 4 is made up of a magnet 9 at least, described magnet 9 is provided with at least one driver 6, its main feature is that magnet 9 can move in ectosome 4 by the driving of described driver 6, between magnet 9 and the endosome 3 relative displacement can take place.
Described magnet 9 has two kinds by the move mode of driver 6 in ectosome 4: a kind of is that described magnet 9 moves vertically by driver 6, and to be described magnet 9 move along warp-wise by driver 6 another kind.
Described magnet 9 has two kinds by the connected mode of driver 6 in ectosome 4: a kind of is that described magnet 9 is connected with shell 7 by driver 6, and another kind is that described magnet 9 is connected with end casing 8 by driver 6.
