Problems solved by technology
[0007] 1) Due to structural reasons, the energy stored in the vortex spring is limited. If it is to be used as an energy storage device for a generator, the size and strength of the vortex spring need to be greatly increased. The mass has also increased substantially, which requires the use of a large amount of energy storage material, which is expensive
[0008] 2) After increasing the energy storage capacity of the vortex spring, the size of the vortex spring is too large, which is not conducive to real-time control of the working conditions of the large vortex spring

Embodiment Construction
[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.
[0043] The structural size of the traditional planar scroll spring has certain restrictions, generally the thickness does not exceed 4mm, and the width does not exceed 80mm. The thickness, width and length of the coil springs used in the mechanical energy storage method based on large coil springs are much larger than those of traditional coil springs, and the mass of the coil springs is also increased accordingly. For this large-scale energy storage scroll spring, the present invention provides a method for improving the energy storage density, figure 2 Be the flowchart of the method of the present invention, as figure 2 As shown, methods to increase energy storage density include:
[0044] Step 101, determining the neutral plane of the torque wh...

The invention provides a method for improving energy storage density and an energy storing device of a wind-driven generator set, wherein the method for improving the energy storage density comprises: determining a neutral surface of a torque of a volute spring blade worked in bending way; processing semicircular grooves at the left side and the right side of the volute spring blade; placing the circle centers of the semicircular grooves on the neutral surface so as to obtain an opened volute spring sheet with left and right symmetrically arranged; arranging a plurality of opened groove volume spring sheets in parallel along the left and right directions so as to form a large volume spring with a section in the shape of long strip; fixing one end of the large volume spring to a primary shaft of an energy storing device, and fixing the other end of that to a box body of the energy storing device. By adopting the method and the device provided by the invention, the storing capacity of the volute spring can be improved, as well as the quality of the volute spring can be controlled, and the energy storing density of the large planar volute spring can be greatly raised.
Description
technical field [0001] The invention relates to energy storage technology of a power generation system, in particular to a method for increasing energy storage density and an energy storage device for a wind power generating set. Background technique [0002] Safety, high quality, and economy are the basic requirements for the power system. How to make good adjustments to the power system so that the power system can be adjusted economically and effectively according to the load of the grid or according to the power generation capacity has always been a focus of the industry. [0003] For large-scale power grids, the transmission network is equivalent to an electric energy concentration container. All power plants in the system inject electric energy into this container, and users take electric energy from this container through the power distribution network. Generally, the generator capacity backup method is used for mediation In case of emergency, load shedding or generat...
