Abstract

The embodiment of the invention discloses a control method and device of wave energy power generation equipment and a wave energy power generation system. The method comprises the steps of obtaining the pressure in a hydraulic pipeline, and judging whether the pressure in the hydraulic pipeline is in a preset pressure range or not; when the pressure is in the preset pressure range, determining theoptimal rotating speed of a hydraulic motor according to the pressure in the hydraulic pipeline, and controlling the rotating speed of the hydraulic motor to be the optimal rotating speed; when the pressure in the hydraulic pipeline is greater than the upper limit pressure of the preset pressure range, starting a pressure reducing valve to reduce pressure until the pressure in the hydraulic pipeline is in the preset pressure range; or when the pressure in the hydraulic pipeline is smaller than the lower limit pressure of the preset pressure range, controlling the hydraulic motor to stop rotating, and controlling an energy accumulator to store energy until the pressure in the hydraulic pipeline is in the preset pressure range. The maximization of energy conversion is realized, the conversion efficiency is improved, and the wave energy power generation equipment can stably and efficiently generate power.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of new energy power generation, and in particular to a method and device for wave energy power generation equipment, and a wave energy power generation system. Background technique [0002] Ocean wave energy is a clean and non-polluting renewable energy. There is great potential for the development of ocean wave energy. At the same time, wave energy is also one of the most abundant energy sources in ocean energy. It is the ocean energy that has been studied most recently in ocean energy utilization research. The technology has matured and is entering or approaching the stage of commercial development. [0003] However, since the waves are random and difficult to predict, and the power generation often depends on the front-end wave conditions, a large inrush current will be generated during huge waves and insufficient power generation will occur during light waves. It is extremely u...
