Description

Vegetable greenhouse wind power generation heating system

Technical Field

The invention belongs to the technical field of clean energy, and particularly relates to a wind power generation heating system for a vegetable greenhouse.

Background

Large-scale wind power is widely distributed in China, is totally a megawatt wind power generator and a large-area photovoltaic, is merged into a large power grid, and is transmitted to a city consumption center in a long-distance power transmission and transformation mode. Since two-carbon targets around the world are proposed in recent years, rural distributed power stations are proposed, but distributed power stations for natural energy power generation are all aimed at grid connection, and farmers do not enjoy the distributed power stations directly. Wind power generation technologies are generally classified into grid-connected use and off-grid use. The small-sized conventional grid-connected and grid-disconnected system comprises a wind driven generator, a grid-connected (or grid-disconnected) controller and a grid-connected (or grid-disconnected) inverter, wherein the off-grid system needs a storage battery besides the controller and the inverter. The controller and the inverter are expensive, and the price of the inverter is equivalent to that of the wind driven generator (with the same power). The higher price makes the wind energy utilization prohibitive for farmers. Wind power generation is unstable, household appliances need to utilize wind power, an inverter is required to be arranged besides a controller, and the household appliances can be used only after stable output voltage is obtained. The average farmer does not know how to utilize this unstable power. At present, cheap and practical technologies and products for directly warming the greenhouse by utilizing wind energy do not exist.

In the three north areas of China, a plurality of areas with very rich wind resources exist, the annual average wind speed reaches more than 6 m/s, wind blowing is not stopped all the day after the three seasons of autumn, winter and spring, and the wind power is very sufficient. On the other hand, to achieve the two carbon goals, governments have been actively pushing coal to change electricity, but the high consumption of electric heating makes the promotion difficult. How to utilize abundant wind energy to heat for the use in cold seasons more than half a year becomes the technical problem that needs to be solved.
