NOVELTY - The system has a main structure shaft or small reservoir (7) attached at a rear part of a main structure (1). An intake opening is formed in the main structure, where amount of ocean water (5) captured at different wave heights are controlled by changing shape of the intake opening of the main structure for the ocean wave height variations in potential energy due to normal wave height changes and the normal ocean tide changes. A return water conduit collects surrounding backwash and undertow to assist in-out flux of the system and influx to a turbine/generator (6).    USE - System i.e. hydro system, for controlled capture of full ocean wave cycle of potential and kinetic energy of the incoming ocean wave i.e. surface and sub-surface waves, near an ocean shore with the conversion of energy into electrical energy using a turbine/generator for foreign or domestic use.    ADVANTAGE - The system ensures overall control of velocity of ocean water output and effectiveness, and can convert wave energy into electrical energy by a turbine/generator. The system can capture full ocean wave cycle of energy and control tide, period and efflux speed variations in an effective manner, and realizes conversion of wave energy into electrical energy by using a turbine/generator. The system allows utilization of a hydro turbine so as to improve effectiveness and working efficiency of the system by determining amounts of potential capture of energy, where storage collected in a reservoir can be utilized to mediate the energy required to balance the head differences between the high and low tides, thus providing better control effect for the turbine/generator. The system utilizes a monitoring device for monitoring the output flow in conjunction with a microprocessor so as determine the amount of output to release from the reservoir with better control effect.
