An Improved Hydraulic Energy Storage Wave Power-Generation System Based on QPR Control

According to the inherent characteristics of hydraulic power take-off (PTO) system, output a generator tends be intermittent when wave is random. Therefore, this paper aims improve effective utilization energy and reduce intermittency by constructing topology with two branches transmit electrical energy. Firstly, wave-to-wire (W2W) model system constructed. Secondly, W2W simulated using synovial quasi-proportional resonance (QPR) control regular irregular incident waves, results PI are compared. Then, strategy in simulation verified experiments. The experimental show that has better performance, stability greatly improved.
