Power generator group.
Background technique
For wind energy as a kind of clean renewable energy, the amount of accumulateing is huge, and the wind power station built at present is all by big
The wind power generating set of amount is constituted, and each wind-power electricity generation group converts mechanical energy for the kinetic energy of wind by wind wheel, then passes through power generation
Machine converts power output into power grid for mechanical energy.However, the wind-force of wind field natural wind, wind speed are highly unstable, wind-force,
The size of wind speed all changes constantly, and especially when the wind speed of wind field is excessive, wind speed is greater than wind-driven generator group wind-wheel
Cut-out wind speed degree can damage wind power generating set if not reducing the wind energy captured on impeller by feather, if carrying out
Feather adjustment, then can lose part wind energy；Sometimes the wind speed of wind field is sometimes fast and sometimes slow, and generating set is driven when wind speed is higher
Wind wheel fast turn-around, but the wind speed of natural wind is possible to reduce suddenly with the variation of wind-force and wind direction, at this time generating set

There is the wind power generating set technical solution for determining inertia energy-storing flywheel, can be when wind field wind speed be excessively high by introducing energy-storing flywheel, it will
A part of wind energy is stored on flywheel, and when wind speed reduces, release flywheel energy feeds back to wind driven generation set main shaft and sent out
Electricity improves wind power generating set to the utilization efficiency of wind energy to a certain extent.However, the inertia due to its energy-storing flywheel is permanent
It is fixed, when introducing suddenly in spindle drive chain or cut off flywheel inertia, it may cause biggish impulsion and the fluctuation of speed, flywheel exists
Also the reasonable adjusting to the speed of mainshaft can not be effectively realized during accumulation of energy and exoergic.
Therefore, how to solve the problems, such as abandonment when wind field wind speed is excessively high, and change accumulation of energy capacity when wind speed persistently rises, and
Stablize the speed of mainshaft, not will lead to main shaft impulsion and the biggish fluctuation of speed, become as technical problem urgently to be resolved.
