Problems solved by technology

[0003] Under normal circumstances, there is mainly one method for calculating and analyzing the wave height data series of ocean waves in a certain period of time in the future. After the wave height of the position is determined, according to the distance between the wave height sensor acquisition device and the ocean wave power generation system and the speed of wave propagation forward, the ocean wave power generation system is optimally controlled, so that the ocean wave power generation system and the operation of the current ocean wave height The frequency reaches resonance; for this method, a wave height sensor acquisition device needs to be installed independently in the ocean, which not only increases the implementation cost of the installation project, but also reduces the utilization efficiency of the ocean wave area, especially for large-scale ocean wave power generation arrays.

Embodiment Construction

[0031] In order to understand the present invention in more detail, the specific implementation steps of the present invention will be described in detail in conjunction with the accompanying drawings.

[0032] refer to figure 1 As shown, the ocean wave height calculation method based on the moving average analysis model includes the following steps:

[0033] Step 1: Use sensors to collect and store the historical and current values ​​of ocean wave heights to form a sequence X(N), where N is the number of data sequences, and N is an appropriate integer greater than zero (the larger N is, the greater the use of mobile The more accurate the ocean wave height data sequence calculated by the average analysis model in a certain period of time in the future), the acquisition frequency of the ocean wave height by the sensor is not lower than 30 Hz. ;

[0034] Step 2: Perform differential calculation on the historical value and current value of the ocean wave height data series to e...

Abstract

The invention discloses a control method based on a moving average analysis model for an ocean wave power generation device. The control method comprises the following steps that 1, a sensor with a data storage function is utilized to collect and store a historical value and a current value of an ocean wave height; 2, through establishing the moving average analysis model, on the basis that the historical value and the current value of the ocean wave height are analyzed, the height of ocean waves in a period of time in future is predicted; and 3, the motion state of the ocean wave power generation device is optimized and controlled according to a prediction value, so that the efficiency of converting wave energy into electric energy by the ocean wave power generation device is improved.

Description

technical field [0001] The invention discloses a control method of an ocean wave power generation device based on a moving average analysis model, belonging to the field of data analysis and control. Background technique [0002] The role of the ocean wave power generation device is to convert ocean wave energy into electrical energy, and then supply power to electrical equipment on offshore platforms and remote islands, or conduct long-distance grid-connected power transmission. In the case of less capital investment, how to maximize the conversion of ocean wave energy into electrical energy has become a hot issue in the field of ocean wave power generation technology. According to the theory of energy transfer and mechanical oscillation, only when the operating frequency of the ocean wave power generation device and the operating frequency of ocean waves resonate, can the ocean wave energy be converted into electrical energy to the maximum extent. Therefore, it is particu...
