Resultant-force wind power generation device with energy storage function

Abstract

A resultant-force wind power generation device with an energy storage function overcomes the shortcomings that a single windmill is small in force and the power generation force cannot be integrated easily. According to the adopted scheme, the device comprises a group of windmills, a transmission device, an energy storage device and a generator set; the group of windmills rotate windward to simultaneously drive the transmission device and the generator and store the energy in an energy storage device; when the windward rotating power of the windmills is insufficient, the energy storage device drives the transmission device to rotate continually or assists the transmission device in rotation. The resultant-force wind power generation device has the benefits that the group of windmills have a large resultant force in driving the generator and can be optionally combined according to different wind field situations, so that manoeuvrability and flexibility are achieved, the wind power utilization ratio and conversion efficiency are high, the wind energy can be stored and released and converted into continuous output kinetic energy, and accordingly, the generator is enabled to rotate continually.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a continuous power generation device with energy storage regulation by means of a group of windmills. Background technique [0002] The traditional wind power generation devices are all set up independently with a single unit, the power is small, and the windward angle of the blades is adjusted to achieve uniform rotation to drive the generator to generate electricity. The disadvantages of the existing technology are: the generated energy fluctuates greatly and is not easy to integrate, and the wind force Hours cannot drive the blades to rotate, causing the generator to stop generating power, and within a certain power generation cycle, limited by the size of the wind, the output power is discontinuous, affecting the power supply to the grid or users. Contents of the invention [0003] The present invention overcomes the technical defect in the prior art that when the wind ...

Problems solved by technology

[0003] The present invention overcomes the technical defect in the prior art that when the wind force is strong, a large amount of wind force is wasted, and the blades cannot be rotated when the wind force is small, causing the generator to stop generating power. The present invention provides a combined wind power generation device with energy storage, The device is equipped with a wind guide mechanism, which improves the wind power conversion efficiency, and the mechanical energy storage part can absorb and release energy to ensure the continuous kinetic energy supply of the generator
