Sea state test method for wave energy device

Abstract

The invention discloses a real sea state testing method for a wave energy device. A wave viewer arranged in the wave-side direction of the sea area where the wave energy device is arranged is used for monitoring the wave condition of the working sea area of the wave energy device; an electric power detector arranged at the power output end of the wave energy device is used for measuring the electric power data of the wave energy device; the acquired wave condition and electric power data are analyzed; power characteristic analyzing areas are partitioned; waves and electric power data, which represent data points in each power characteristic analyzing area, are calculated; a power performance curve of the device is fitted; integrating the history wave data of the sea area where the wave energy device is arranged, the annual energy output of the wave energy device is estimated; the medium energy output efficiency of the wave energy device is calculated. The method has the advantages that the evaluation period is short; the cost is low; scientific reference is provided for technical research and development.

Description

technical field [0001] The invention relates to ocean measurement technology, and mainly relates to an on-site testing method for index parameters of wave energy devices. Background technique [0002] The wave energy device captures the energy of waves in the ocean and converts it into electrical energy output. It is a new type of green and environmentally friendly renewable energy technology. The power output characteristics, annual power generation capacity and power generation efficiency of wave energy devices are the core technical indicators in the process of industrialization, and play an important role in the promotion and utilization of wave energy development. However, the randomness of wave energy under real sea conditions is extremely strong, the energy density in the same sea area varies greatly from year to year, and there are various forms of wave energy devices, and the energy capture and output are unstable, which makes the above three indicators The test ha...

Problems solved by technology

However, the randomness of wave energy under real sea conditions is extremely strong, the energy density in the same sea area varies greatly from year to year, and there are various forms of wave energy devices, and the energy capture and output are unstable, which makes the above three indicators The test has increased the difficulty and put forward higher requirements for the test method

At present, there are no mature and complete test methods for the three indicators of power output characteristics, annual power generation capacity and power generation efficiency of wave energy devices under actual sea conditions at home and abroad, especially in the short-term test and evaluation methods.
