[0052] This embodiment includes a vertical axis wind power generator and a guide structure plate body, the outside of the vertical axis wind power generator is provided with a streamlined wind guide structure plate body, which is used to increase the wind energy density, and the vertical axis wind power generator is arranged on the guide structure Inside the wind structure panel.

[0053] Among them, the first-stage supercharger 1 and the secon...

Embodiment 3

[0056] Now referring to appendixes 1 and 6, the description is as follows in conjunction with the embodiment: a wind power generator energy superposition storage system and method, this embodiment is basically the same as embodiment 1, the difference is that: through the reflector 14, the speed of sunlight heating is increased, Realize rapid heating and pressurization of the supercharger, and accelerate the continuous operation of the working medium. In this embodiment, more than two pressure-guiding working medium expanders 6 are provided.

[0057] Combined with the embodiment, the description is as follows: a wind power generator energy superposition storage system and method, the first-stage supercharger 1 and the second-stage supercharger 2 are installed on the rotating shaft, and the speed of sunlight heating is increased through the reflector 14 . The heated supercharger completes the circulation of the working fluid, and enters the backlight area of ​​the shield through ...

Abstract

The invention provides an energy superposition and storage system and an energy superposition and storage method for a wind driven generator. The energy superposition and storage system comprises a working medium pressure circulation system, a transmission medium circulation system, a pressurization circulation system and an air energy circulation system; pressurizers can realize heating and pressurization in different time periods by virtue of sequenced arrangement; the pressurizers can be used for directly absorbing solar energy; a pressure guide working medium in a first-stage pressurizer is firstly heated and pressurized; after being pressurized, the pressure guide working medium is discharged to a second-stage pressurized in the next stage by virtue of a second-stage pressurization pump; a third-stage pressurizer is used for heating and pressurizing the pressure guide working medium again by absorbing the solar energy; the pressure guide working medium is discharged to a pressureguide working medium expander by using a third-stage pressurizing device in the next stage; and subsequently the pressure guide working medium exchanges heat with a transmission medium inside a heat exchange pipeline inside the pressure guide working medium expander so as to generate saturated air. By adopting the energy superposition and storage system and the energy superposition and storage method for the wind driven generator provided by the invention, random wind energy and solar radiant heat energy are pressurized and stored stage by stage by virtue of a plurality of pressurizers which are arranged in sequence, so the utilization efficiency of energy is improved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power generator energy superposition storage system and method. Background technique [0002] Energy is the cornerstone of the development of human society and the driving force of economic activities and development. Today, the exploitable reserves of traditional fossil energy are decreasing year by year, facing exhaustion; the extensive use of energy causes environmental pollution. Wind energy is a clean renewable energy and one of the representatives of new energy with huge reserves. [0003] However, Class II and III wind circles account for 85% of the wind resource. According to the measured data of high-rise buildings, the wind speed of 0.5m / s-2m / s is almost non-stop for 24 hours. This part of wind resources has a high frequency of wind generation, and has obvious intermittent and random shortcomings. This part of wind resources has a low energy flow density a...
