Description
Technical Field
The invention relates to the technical field of wind energy conversion and utilization, in particular to a wind non-electric conversion system for averaging output energy.
Background
Wind is an intermittent renewable energy source, but the power of the wind in a short time is greatly changed, such as unstable wind speed, and the energy output is intermittent and incoherent and has larger fluctuation under the condition of small wind and no wind, so that the stability of the wind energy utilization and transmission performance is affected. This necessitates the use of wind power with other energy sources or energy storage facilities to create a stable power output. The wind power source of China is rich, and the wind power source has very important significance for utilizing wind energy, especially for coastal islands, remote mountain areas inconvenient in traffic, meadow and thin grassland pastures and rural areas and frontier areas far away from a power grid in China.
The scheme of wind energy utilization in the prior art is as follows:
1. the windmill converts wind energy into electric energy, and the windmill rotates to generate electricity and do work only when the wind speed reaches 3 m/s (the feeling of a breeze surface). The wind power generation device is operated in a limited wind speed interval, the output power is kept to be constant by a conversion device (speed increasing mechanism), wind energy is converted into mechanical energy, the mechanical energy is converted into electric energy, and finally the wind power generation device becomes usable clean wind power.
2. Windmills convert wind energy into kinetic energy, i.e. wind drives a paddle wheel to rotate to bring power, and the wind energy is converted into mechanical energy through a conversion device to grind grains, crude salt, tobacco leaves, oil extraction, felt and paper, remove accumulated water in marsh lands, and are widely used in various industries such as windmill driving mill, sawmill and paper mill operation, and agricultural and sideline product processing by utilizing windmills.
An overview of the two schemes is that the realization precondition is that continuous wind energy is intercepted by a collecting device. However, in actual conditions, the stability of wind is poor, the wind speed is changed at any time, in actual wind energy utilization, the actual conditions of the loud cry of a birds, stopping of energy driving production work, and the like are likely to be encountered, continuous impact on a power grid and fluctuation of power sources required by various industrial works are brought, the efficient utilization of wind energy under ideal conditions is difficult to meet, and the use quality of wind energy is seriously affected.
Furthermore, the existing wind power generation device and the wind energy conversion kinetic energy direct acting device have the precondition that the energy conversion and utilization can be realized only by obtaining continuous wind energy. Meanwhile, the utilization of wind speed is limited, only the wind speed of a certain interval section can be utilized, and no energy can be converted and utilized when no wind exists, so that a series of incoherent and discontinuous gaps are utilized for energy utilization, the average output cannot be realized, and large fluctuation impact is generated on a power system. When the wind energy conversion kinetic energy is utilized, the wind speed cannot be regulated and controlled to meet the external load driving under the condition of large range, so that the wind energy conversion loss is large, and the utilization rate is low. Meanwhile, the problem of no energy input and output in windless conditions also exists. The root cause of the above problems is the lack of a wind energy storage and redistribution link; if surplus wind energy is stored and released controllably at low wind speed or no wind, the quality and utilization rate of wind energy can be improved greatly.
