Wind energy stable and continuous power generation system and control method on the roof of a high-rise building

Abstract

The invention discloses a system for generating electricity stably and continuously through wind energy generated on a roof of a high-rise building and a control method. A wind collection device is arranged on the high-rise building. The output end of the wind collection device is connected with the input end of a pressure-stabilized vessel through a first one-way valve. The output end of the pressure-stabilized vessel is connected with a mechanically-operated reversing valve. One outlet of the mechanically-operated reversing valve is connected with one end of an air cylinder of a gas-liquid converter, and the other outlet of the mechanically-operated reversing valve is connected with the other end of the air cylinder of the gas-liquid converter. A hydraulic oil chamber outlet in the left end of the gas-liquid converter is connected with an energy accumulator through another one-way valve, and a hydraulic oil chamber outlet in the right end of the gas-liquid converter is connected with the energy accumulator through another one-way valve. An outlet of the energy accumulator is connected with an inlet of a variable displacement motor, and the variable displacement motor is in sequential series connection with a first coupling, a generator / electromotor, a second coupling and a pump / motor. An inlet of the pump / motor is connected with an inlet of a proportional reversing valve. An outlet of the pump / motor is connected with a first outlet of the proportional reversing valve and a sixth one-way valve. The sixth one-way valve is connected with a second outlet of the proportional reversing valve and an energy storage device. By means of the system and the control method, the turbulent wind energy generated at the roof of the high-rise building is effectively utilized for generating electricity, and the problems that wind power generation is unstable, discontinuous and complex in control are solved.

Description

technical field [0001] The invention belongs to the technical field of wind energy development and utilization and high-rise building energy conservation, and in particular relates to a wind energy power generation system on the top of high-rise buildings. Background technique [0002] As a kind of green energy among renewable energy sources, wind power generation has been widely used and promoted in areas with abundant wind resources, superior geographical conditions or inconvenient grid power supply. Due to the instability of wind power and the fact that cities are often located in grid-covered areas, even with good wind power generation conditions, wind power generation is rarely used. But high-rise building because of having certain height and its special environment, even if local wind force condition is bad, high-rise building roof also can have certain wind force. And high-rise buildings themselves consume a huge amount of energy. Therefore, making full use of the wi...
