Control method and device for wave energy generating equipment, wave energy generating system

Abstract

The embodiment of the present invention discloses a control method and device for wave energy power generation equipment, and a wave energy power generation system. By obtaining the pressure in the hydraulic pipeline in real time; judging whether the pressure in the hydraulic pipeline is within the preset pressure range; and when When it is in the preset pressure range, according to the pressure in the hydraulic pipeline, determine the optimal speed of the hydraulic motor, and control the speed of the hydraulic motor to the optimal speed; and when the pressure in the hydraulic pipeline is greater than the upper limit of the preset pressure range When the pressure is high, start the pressure reducing valve to decompress until the pressure in the hydraulic pipeline is within the preset pressure range; or, when the pressure in the hydraulic pipeline is lower than the lower limit pressure of the preset pressure range, control the hydraulic motor to stop rotating, And control the accumulator to store energy until the pressure in the hydraulic pipeline is within the preset pressure range. The embodiment of the present invention realizes the maximization of energy conversion and improves the conversion efficiency, so that the wave energy generating equipment can generate stable and efficient power generation.

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...

[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 unstable, which will pose a great threat to the power grid, and will also cause the problem of low overall power generation efficiency of wave energy
