Description
The method and the device of the automatic load-regulating speed stabilizing's voltage stabilization and frequency stabilization of wind-power electricity generation.Be in the work wind speed range that wind-driven generator is selected.By regulating the wind-driven generator load, reach the method and the device of constant wind power generator rotating speed, voltage, frequency.
The current habitual both at home and abroad change air vane resistance or the method and the device of wind-exposuring area.To cut wind speed amplitude generating efficiency low because of deleting, complex structure, cost height.
1. design basic theory of the present invention:
When utilizing wind-power electricity generation, wind speed is unsettled, and the wind speed luffing is constantly to change.The rotating speed of wind-driven generator, voltage, frequency are also just unstable.For stabilized (steady-state) speed and voltage, the current methods that change blade resistance or wind-exposuring area that adopt more.But because these methods and device have deficiency.The present invention is according to wind-driven generator characteristic-under the constant condition of wind speed.The rotating speed of wind-driven generator and load are inversely proportional to and close is foundation, conceives the method and the device of the automatic load-regulating speed stabilizing's voltage stabilization and frequency stabilization of wind-driven generator of the present invention.
Embodiment of the present invention be with generator voltage, electric current, frequency, rotating speed, etc. running parameter be chosen for transducing signal.Make actuator by logic program by feedback line, be switched on or switched off and wait to transfer on-load switch group row.Reach the purpose of automatic load-regulating speed stabilizing's voltage stabilization and frequency stabilization in the wind-driven generator work wind speed range.It treats that the accent load is many group transformers, is plurality of groups of storage batteries, is other electric consumers of organizing more.Regulating its also joint group number, is stepless deferrable load.
3. effect unique of the present invention:
(1) the present invention's constant wind power generator rotating speed, voltage, frequency reliably improves power supply quality.
(2) the present invention can improve wind-power electricity generation efficient effectively in work wind speed range internal conversion full width wind energy.
(3) simple in structure, easy to maintenance, cheap.
