Description
Technical field
The utility model 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 power output 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.
On the other hand, blower fan is to make the mode that wind turbine generator adopts usually now by the rotating speed that speed increasing gear improves generator, and its shortcoming is the driving moment that has increased generator, has reduced Wind Power Utilization efficient.
