Abstract

The invention discloses a wind power generation system which comprises a central control system, a power control system, an accessory power system, a transition system and an energy storage device, wherein a power generation machine outputs power for a load by the transition system; when the rated power generation rotation speed is realized, redundant power is stored in the energy storage device and can be used for accessory power generation; the central control system is used for adjusting the angles of rotor blades by an angle controller, so that the wind power area of the rotor blades is enlarged. The wind power generation system disclosed by the invention is reasonable in design, and can be used for adjusting the angles of the rotor blades, so that the wind power utilization rate is increased; in addition, the redundant power generated in a power generation peak can be stored for making up a defect of insufficient power in a power generation peak bottom, and the wind power generation system has the advantage of stability of electric power output.

Description

Technical field [0001] The invention relates to a power generation system, in particular to a new type of wind power generation system, and belongs to the field of electric power technology. Background technique [0002] At present, since clean energy does not emit pollutants, it has been widely used. Among them, clean energy includes nuclear energy and renewable energy. Renewable energy is an inexhaustible energy source, such as hydroelectric power, wind power, solar energy, biomass, ocean tide energy and so on. Among them, wind power is widely used, but wind power is uncontrollable and cannot guarantee the constant wind energy. Therefore, normal wind power generation has peaks and valleys, and the transmitted power fluctuates. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a wind power generation system. [0004] The technical scheme of the present invention is: [0005] A wind power generation system includes a c...
