Hydraulic drive wind power generation system

Abstract

The invention discloses a hydraulic drive wind power generation system, which comprises a drive shaft, a wind tower, a bevel gear unit and a fan blade, wherein an oil storage tank, an oil pump and a gearbox are arranged in the wind tower from bottom to top in sequence; the drive shaft on the gearbox penetrates through the upper end of the wind tower and is connected with a bevel gear in a horizontal direction in the bevel gear unit, and a bevel gear in a vertical direction is connected with the fan blade through a shaft; an oil inlet pipe of the oil pump communicated with an oil tank is arranged on the upper end of the lateral surface of the oil pump, a high-pressure oil pipe communicated with multiple branches is arranged on the lower end of the lateral surface of the oil pump, wherein one branch is respectively communicated with a one-way check valve, a flow control valve and a turbine generator. According to the invention, the wind power is converted to the electric energy through the hydraulic oil, so that the difficulties of energy storage and constant power output are solved. Through hydraulic oil transfer, the generator is installed on the floor, so that the difficulty of motor maintenance is solved. The wind power is used for centralized power generation, so that the parallel difficulty is solved. The wind power efficiency is greatly improved, and the stability of an electric network is improved.

Description

Technical field: [0001] The invention relates to a hydraulic transmission wind power generation system. Background technique: [0002] The current wind turbines all use top-mounted generators, relying on the gearbox to increase the speed of the wind blades to 1500 revolutions per minute, driving the generator to generate electricity, and then connecting to the grid to generate electricity through the inverter device. Due to the different sizes of wind energy, the grid-connected power cannot be controlled. When the wind is strong, the power generation is large, and when the wind is low, the power generation is small, and power storage and control cannot be carried out, which affects the stability of the power grid, and thus limits the prospect of wind power development. . Invention content: [0003] The purpose of the present invention is to provide a hydraulic transmission wind power generation system, which can overcome the above problems existing in the existing wind po...

Problems solved by technology

Due to the different sizes of wind energy, the grid-connected power cannot be controlled. When the wind is strong, the power generation is large, and when the wind is low, the power generation is small. It is impossible to store and control electric energy, which affects the stability of the power grid, and thus limits the prospect of wind power development.
