Multi-mode wind power plant

Abstract

The invention belongs to the technical field of wind power generation, and particularly relates to a multi-mode wind power plant. The multi-mode wind power plant comprises a wind turbine group, a transmission system and a power generation group; the transmission system is used for power connection between the wind turbine group and the power generation group; and the wind turbine group comprises arotating support body, wherein a plurality of blade trusses are uniformly arrayed in the circumferential direction of the rotating support body, blades protruding extending outwards are arranged at the tail end of each blade truss, the blades are rotatably connected to the tail ends of the blade trusses through blade connecting rods, a blocking piece is arranged on each blade truss, and the blocking piece is used for blocking the corresponding blade connecting rod. According to the wind power plant, the manufacture cost is low, the wind energy utilization efficiency is high, the influence onthe ecological environment is small, site selection is convenient, and operation and maintenance are facilitated.

Problems solved by technology

[0003] Under the condition of unstable wind speed, it is difficult for existing generator sets to be connected to the grid, and it is easy to abandon wind and electricity

The generator set weighs tens of tons and is installed at a height of nearly 100 meters. The center of gravity is too high, which poses a safety hazard. The lightning protection facilities are not complete and are prone to lightning strikes. The wind power tower uses too much material to achieve strength and is expensive.

Lifting costs are high

The maintenance cost is too high, and it is difficult to monitor and guarantee the generator set during operation;

[0004] In addition, the existing wind power blades have a long and narrow shape and a fast rotation speed. Because the blades rotate perpendicular to the ground, they occupy a large airspace area and produce translucent disturbance images that make it difficult for birds to identify and affect the migration of migratory birds. There have been incidents where blades have struck birds
