Abstract: This paper presents a new intermittent wave energy generator (WEG) with a hydraulic energy storage accumulator that converts unstable wave energy into stable output power in electrical power generation, and describes its components and working principle along with a real-time control method for stabilizing the output power based on experimental test database. Theoretical models were constructed for the relationship of load versus working pressure and the relationship of hydraulic motor pressure drop versus opening ratio of the proportional flow valve. The latter relationship was verified by experimental data collected using LabVIEW, and a control curve of the opening ratio was used to stabilize the flow rate of hydraulic motor. Experimental results show that the output power of generators can be maintained stable within a certain range and the new WEG, when combined with hydraulic energy storage accumulator and real-time control based on experimental test database, is an effective device for generation of stable and smooth output power.
