Abstract

The invention relates to the technical field of wind power generation, and discloses a turbine rotor assembly for a vertical axis wind power generation system and a power generation system. The turbine rotor assembly comprises a tower and a multi-layer turbine rotor device connected in the tower in the axial direction, wherein the turbine rotor device comprises first streamlined connecting plates,a central supporting column mechanism and blade mechanisms; the central supporting column mechanism is vertically arranged, and the blade mechanisms are horizontally fixed on the peripheral side of the central supporting column mechanism; and the first streamlined connecting plates are arranged between the blade mechanisms of the turbine rotor device at the adjacent upper and lower layers. The power generation system comprises the turbine rotor assembly. When wind energy density is low, the blade mechanisms can rotate, wind energy is converted into electric energy, cut-in wind speed is reduced, cut-out wind speed is increased, generated power is increased, and equivalent full-power hours of a turbine rotor are greatly increased.

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...
