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 capable of outputting energy in an averaged mode.
Background
Wind is an intermittent renewable energy source, but the power of wind changes greatly in a short time, for example, the wind speed is unstable, and the energy output is discontinuous and discontinuous in the states of small wind and no wind, and has larger fluctuation, thereby affecting the stability of the wind energy utilization and transmission performance. This necessitates the use of wind power in conjunction with other energy sources or energy storage facilities to enable a stable power output. The wind power resource is rich in China, the utilization of wind energy is realized, and the wind power resource has very important significance as a reliable way for solving production and living energy resources, especially for coastal islands in China, remote mountain areas with inconvenient traffic, grassland pastures with sparse geodess and rural areas and frontiers far away from power grids.
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 power and do work as long as the wind speed reaches 3 m/s (the feeling of breeze striking the surface). The wind power generation device operates in a limited wind speed interval, output power is kept constant by a conversion device (a speed increasing mechanism), wind energy is converted into mechanical energy, then the mechanical energy is converted into electric energy, and finally the electric energy is converted into usable clean wind power.
2. The windmill converts wind energy into kinetic energy, namely the wind power drives the paddle wheel to rotate to bring power, the wind energy is converted into mechanical energy through the conversion device, the mechanical energy is used for grinding grains, crude salt, tobacco leaves, oil pressing, felts and paper making, and accumulated water in a marshland is widely used in various industries such as windmill driving mills, sawmills and paper mills, and the windmill is used for processing agricultural and sideline products.
Overview the premise for implementing the two schemes is that continuous wind energy is intercepted by the collecting device. However, in the actual situation, the wind stability is poor, the wind speed changes all the time, and in the actual wind energy utilization, the situation that the wind is likely to encounter the actual situation that the energy drives the production work to stop and the like is likely to occur, so that the continuous impact on a power grid and the fluctuation of a power source required by various industrial work are brought, the efficient utilization of the wind energy under an ideal state is difficult to meet, and the use quality of the wind energy is seriously influenced.
Furthermore, the existing wind power generation device and the device for converting wind energy into kinetic energy to directly do work have the precondition that the conversion and utilization of energy can be realized only by acquiring continuous wind energy. Meanwhile, the utilization of wind speed has limitations, only the wind speed in a certain section can be utilized, and no energy can be converted and utilized when no wind exists, so that a series of discontinuous and discontinuous gaps are utilized, the average output cannot be realized, and large fluctuation impact is generated on a power system. When the wind energy is converted into the kinetic energy for utilization, the wind speed cannot be regulated and controlled to meet the requirement of external load driving under the condition of a 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 the absence of wind exists. The fundamental reason for the above problems is the lack of a link for storing and redistributing wind energy; if the surplus wind energy can be stored and released controllably at low wind speed or no wind, the quality and the utilization rate of the wind energy can be greatly improved.
