Problems solved by technology

Due to the influence of environmental factors, such as wind force, sunshine intensity, tide time, etc., the current power stations of clean energy such as wind power, solar energy, and tidal energy often cannot match the power generated by the power grid, which leads to the power generation of these clean energy sources. The generated electric energy cannot be connected to the grid, which leads to a lot of waste
This patent uses stable wind energy at medium and high altitudes as the power generation power, which has the characteristics of high stability. Although the above-mentioned ground generator set can realize the power generation function well, considering that the generated energy needs to be incorporated into the current power grid for use, and The power generation of these stand-alone gensets cannot be adjusted and needs to be redesigned

Description

technical field [0001] This patent relates to an umbrella-type wind power generation system, more specifically, a ground-based power assembly and generator set that cooperates with a mid-high altitude umbrella-type wind power device. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109MW, of which the usable wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. There are two main ways to generate electricity by using high-altitude wind energy: one is to suspend the generator at high altitude; the other is to install the generator on the ground. The power generation system with the generator suspended at high altitude is limited by the weight and volume of the aerial system. The aerial part of the power generation system with the generator ...
