Title:
OSCILLATING WATER COLUMN-TYPE WAVE POWER GENERATION SYSTEM HAVING FLOWRATE CONTROL FUNCTION
Document Type and Number:
WIPO Patent Application WO/2020/111360
Kind Code:
A1
Abstract:
The present invention relates to an oscillating water column-type wave power generation system using sea wave energy, comprising: an oscillating water column chamber allowing seawater to flows therein or be discharged through a seawater inlet provided at one side thereof; an air flow path which is connected to the inside of the oscillating water column chamber, and which allows air to flow therein according to the inflow or discharge of the seawater; a turbine which is provided inside the air flow path and which produces power while rotating according to the flow of air through the air flow path; a flowrate control duct which is provided inside the air flow path and which controls the degree of air flow; and a control unit for controlling the operation of the flowrate control duct, wherein the flowrate control duct includes: an inner pipe forming an inner pipeline; an outer pipe provided so as to encompass the outer circumference of the inner pipe, and spaced from the inner pipe so as to form an outer pipeline; and a control valve which is provided at the outer pipeline, and of which the opening/closing is determined according to a signal of the control unit. Therefore, the present invention regulates, from information about the RPM of the turbine, the flowrate of the air moving in the inner pipeline and the outer pipeline of the flowrate control duct, and thus is effective in maintaining the rated capacity of the power produced by the turbine.
