Experimental research on asynchronous wave energy power generation system

In order to make better use of wave energy, based on floating wave energy device, a new asynchronous wave energy generation system is presented in this paper. Being different with traditional floating wave power generation system in which the motion of hydraulic cylinder piston rod on both sides of the system is synchro-nous operation, the new system is designed for the bilateral asymmetric cylinder stroke operation conditions, expecting the new system can be used in more complex occasions. In this article, the power captured in three different conditions is analyzed through the experimental method, in which the average motion cycle of 4 seconds is selected to investigate the influence of wave period on the power. The performance of the asynchronous condition is very well under the same period. Comparing with the performance in synchronization conditions, the performance of asynchronous system is not too bad, and the power has a higher peak.

A brief explanation is given here: by the operating mode of floating type wave energy power generation system, assuming that the left of the system on a downward route, and the right of the system on a upward route at the same time, now the hydraulic oil in the system from two hydraulic cylinders through hydraulic tube into the hydraulic motor, let the motor rotate at the same time, the rotation of the hydraulic motor drives the generator to generate electricity, hydraulic oil back into the system of hydraulic cylinder through the one-way valve, when the right side of the left sideor is ascending or descending, the hydraulic oil from both sides of the systems flows into the hydraulic motor along the same path as the function of the hydraulically operated direction control valve .Due to the effect of one-way valve, the path of the hydraulic oil is fixed, and there will be no reversal of the hydraulic motor. This kind of condition is asynchronous condition, according to the working principle of the asynchronous wave energy power generation system. When the left of the system is resting, the right of the system is upward or downward, this is working condition of single cylinder movement, studying the actual generating effect of three conditions is also one of the important research contents in this paper.
