FIELD: power industry.
SUBSTANCE: invention relates to hydraulic unit for removal of energy from wave movement. Automatic adjustable hydraulic unit 200 for conversion of wave energy includes pump 201 intended for fluid medium pumping through hydraulic unit 200. Pump 201 has housing 202 forming chamber 203 and piston 207 allowing separation of chamber 203 into working compartment 208 and blind compartment 209. A provision is made for an activating element that is connected to piston 207. The inlet hole is interconnected with working compartment 208 of chamber 203 so that a provision of fluid medium flowing from the inlet hole to working compartment 208 of chamber 203 is provided. The outlet hole is interconnected with working compartment 208 of chamber 203 so that a possibility of fluid medium flowing from working compartment 208 of chamber 203 to the outlet hole is provided. A provision is made for a hydraulic control device having a possibility of control of pump 201 by controlling the fluid medium pressure at the inlet hole and the outlet hole so that optimisation of pump 201 output power as a response to tidal variations and/or sea state is provided. Control of the fluid medium pressure at the inlet hole and the outlet hole is performed in compliance with a control algorithm.
EFFECT: invention is aimed at achievement of higher volumes of production at lower costs.
