Abstract: A floating wave power plant receives the energy of a sea wave. Improving the efficiency of converting wave energy into a mechanical ability to control the flow of water through a hydro turbine. The article deals with the issues of checking the operation of units of a floating wave power plant with a regular wave process. A design of a wave receiver in the form of a spoiler trap with numerous chambers that scatter the reflected wave flux is proposed. The dependences for finding the total energy flow in the conduit of a screw hydroturbine are given. A method is proposed for determining the mass of water entering the spoiler trap. The need to ensure synchronization of the throughput capacity of the conduit with regular wave processes is shown. Synchronization methods are discussed, an actuator in the form of a controlled pneumatic actuator of a leaf damper at the conduit outlet is proposed. A relay algorithm for controlling the synchronization system is proposed, and the results of its simulation study are presented.

Keywords: energy resource of regular waves, hydro turbine power, phase synchronization.
