Independent wind-solar hybrid power generation equipment

Abstract

The invention relates to independent wind-solar hybrid power generation equipment. The independent wind-solar hybrid power generation equipment comprises a mounting column and a plurality of wind power generation sets distributed at the upper end of the mounting column up and down, wherein a photovoltaic power generation set is arranged at the upper end of the wind power generation set at the topmost end; each wind power generation set comprises a wind guide frame and a generator arranged in the wind guide frame, and a plurality of vertical fan blades distributed in an equal circumference modeare arranged on the outer side of the generator; each wind guide frame comprises an annular wind inlet frame body and wind outlet plate bodies arranged at the upper end and the lower end of the windinlet frame body, and the wind inlet frame body and the wind outlet plate bodies are connected to form a frame structure allowing the generator and the vertical fan blades to be embedded; and wind drives the vertical fan blades to rotate through the wind inlet frame body, so that the generator can convert mechanical energy into electric energy for storage and flow out of the wind outlet plate bodies at the upper end and the lower end. The independent wind-solar hybrid power generation equipment has the following advantages that integrated installation of the plurality of wind power generationsets and the photovoltaic power generation set can be achieved under a condition that the occupied area is not changed, the maximum power generation efficiency at the minimum size is achieved, and theservice life and the air draft effect of the vertical fan blades are guaranteed.

Description

Technical field: [0001] The invention belongs to the field of wind and solar power generation, and specifically relates to an independent wind and solar complementary power generation equipment. Background technique: [0002] Wind-solar hybrid power generation equipment uses solar energy and wind generators (converting alternating current to direct current) to store the generated electrical energy in the battery pack. When the user needs electricity, the inverter converts the direct current stored in the battery pack into alternating current. The power transmission line is sent to the user's load. The wind and solar hybrid power generation system is a new type of energy power generation system that uses the complementarity of wind and solar resources and has a higher cost performance. [0003] The existing wind-solar hybrid power generation equipment has two structural forms: one is to separate and combine the wind power generation group and the photovoltaic panel, and the photovol...

Problems solved by technology

[0003] The existing wind-solar hybrid power generation equipment has two structural forms: one is to separate and combine the wind power generation unit and the photovoltaic panel, and the photovoltaic panel is installed obliquely on the ground near the wind power generation unit; the other is to install the photovoltaic panel on the installation column On the side wall of the wind farm, the wind power generation unit is placed on the top of the installation column; both of these two structural forms only realize the connection of a single wind power generation , telecommunications base towers, etc. The structure of a single wind power generation unit and photovoltaic panels cannot meet the needs of use, and it needs to be equipped with multiple sets of wind and solar hybrid equipment, which takes up a lot of space;

[0004] Secondly, for the wind blades of the wind power generation unit, the vertical axis wind blades use special aerodynamic principles, and the power generation is relatively large when the wind speed is low. The vertical axis wind blades have high wind energy utilization, low start-up wind speed, and low noise. Such advantages have been gradually recognized and valued by people, but the vertical axis wind blades have the following defects: 1. The vertical length of the vertical wind blades is longer, and the contact resistance with the wind is relatively large. When the wind blows the blades, it is easy to make the blades Deformation, damage or looseness occurs between the connection with the generator, which affects the power generation efficiency of the wind power generation unit; 2. The vertical blade adopts a vertical flat structure. When encountering strong winds in different directions, the induced wind of the vertical blade The performance is poor, and it is easy to shake. The contact resistance generated by the wind on the vertical blades is concentrated on the connection between the vertical blades and the wind power generation unit (that is, the middle position of the blades), so it is very easy to break the blades or break the middle. Deformation and damage, resulting in poor air induction effect
