Abstract

The invention discloses an offshore floating wind power generation device with a constant-pressure liquid energy storage function. The device comprises a spar platform tower, a gas energy storage device is arranged in the spar platform tower, a wind wheel rotor is mounted on the upper portion of the spar platform tower and in rigid connection with a variable pump, a water inlet of the variable pump is connected with the sea through a guide pipe, and a water outlet of the variable pump is connected with an input inlet of a proportional valve; and one way of an output outlet of the proportionalvalve is in spray connection with a pelton turbine through a main spray nozzle, and the other way of the output outlet of the proportional valve enters a reversing valve; and a left outlet of the reversing valve communicates with a seawater cavity of the lower portion of a gas-liquid energy storage device, an air cavity of the upper portion of the gas-liquid energy storage device communicates withan air cavity of the gas energy storage device through a pipeline, a right outlet of the reversing valve is in spray connection with the pelton turbine through an auxiliary spray nozzle, the pelton turbine is in rigid connection with an electric generator, and electric energy generated by the electric generator is connected with an external grid. The device provided by the invention is simple instructure and reliable in working.

Description

technical field [0001] The invention belongs to the technical field of energy storage for offshore power generation, and relates to an offshore floating wind power generation device with constant-pressure liquid energy storage. Background technique [0002] Compared with land wind energy, offshore wind energy has natural advantages. The significant advantages of high wind speed, low wind shear, and low turbulence have made offshore wind power develop rapidly in recent years, and will occupy an increasingly important position in the future wind power industry. . Due to the discontinuity of wind energy, the integration of wind power into the grid has become the biggest problem in the development of wind power. The development of energy storage technology provides a new method to solve the grid connection problem caused by wind power fluctuations. [0003] Existing pumped hydro storage is the most mature energy storage method in large-scale energy storage, but subject to geog...
