Experimental study on heave performance of a new wave energy power generation device based on regular waves

Abstract

As an important form of ocean energy, wave energy is gradually being developed and utilized by coastal countries around the world. Researchers have developed various forms of wave energy conversion devices. In this paper, a new type of horizontal rotor wave energy power generation device is designed and manufactured. The device is in a moored floating state when working at sea. The heave belongs to the vertical movement up and down, which directly affects the stability of the device. Based on the engineering prototype making model and conducting regular wave experiments, four test conditions with the same period and different wave heights were designed to verify the influence of wave height changes on heave plates of different shapes and different installation distances on the stability of the device. Determining the shape of the heave plate and the optimal installation distance under the test conditions provides a theoretical basis for the manufacture of engineering prototypes and sea trials.
