Abstract

The invention relates to the technical field of wind power generation, and discloses a turbine rotor assembly and a power generation system for a vertical axis wind power generation system. The turbine rotor assembly includes a tower frame and an axially connected multi-layer turbine rotor device inside the tower frame. The turbine rotor device includes: a first streamlined connecting plate, a central support column mechanism and a blade mechanism; the center support column mechanism is vertically arranged The vane mechanism is horizontally fixed on the peripheral side of the central support column mechanism; the first streamlined connecting plate is arranged between the vane mechanisms of the adjacent upper and lower turbine rotor devices. A power generation system includes a turbine rotor assembly of the present invention. In the present invention, when the wind energy density is low, the blade mechanism can also rotate and be converted into electric energy, which reduces the cut-in wind speed, increases the cut-out wind speed, increases the power generation, and greatly increases the equivalent full-power hours of the turbine rotor.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a turbine rotor assembly and a power generation system for a vertical axis wind power generation system. Background technique [0002] Due to the difficulties in power consumption in Northwest, North and Northeast my country, the phenomenon of abandoned wind is relatively serious. With the innovation and development of low wind speed technology, low wind speed areas that had no development value before are gradually being utilized by the wind power field. In order to have economic development value in the low wind speed area, the wind energy density acting on the wind rotor blades must reach 0.08-0.17kw / m 2 , but for wind energy density lower than 0.08kw / m 2 cannot be used directly. [0003] As for the rotor of the three-bladed horizontal axis wind turbine, the power of the wind turbine can be increased by increasing the diameter of the rotor. However, if the ro...
