Electric energy storage system of water wave generating device and control method thereof

The present invention provides an electric energy storage system of a water wave generating device and a control method thereof. Aiming at the characteristics that electrical signals generated by water wave generating devices working on rivers and lakes are not stable, boost and buck modules are arranged and used for adjusting voltage lower and higher than a reference voltage value to the reference voltage value, thereby bringing convenience for storage; aiming at the problem that the electric energy storage system itself is high in electric energy loss, a scheme of parallel-connection multiple groups of charging protection circuits is proposed, and a scheme where a plurality of charging protection sub-modules in each group of charging protection circuit are connected in series is adopted to further reduce electric energy loss, thereby well solving the problem that the energy storage system of the conventional water wave generating device is low in energy storage efficiency. The electric energy storage system provided by the present invention is high in energy storage efficiency, and users can visually learn system performance, facilitating popularization and application.
