Design of Maximum Power of Wave Energy Based on Differential Equation

The demand for energy in today's human society is increasing, but the existing power generation method is difficult to make up for the current and future energy gap, and the existing power generation method is still based on fossil fuels, which will pollute the environment. At the same time, there is a large amount of wave energy in the ocean, which is a good new energy that has not been developed yet, so the extraction of wave energy has become a hot topic. At present, there are several wave energy extraction devices. This paper makes an in-depth study on the application of Power Take-Off (PTO) in WEC. The device is a passively controlled point suction wave energy device. The float will move under the action of the waves, while the vibrator will resonate with the float under the drive of the spring. The damper connected to the base will use the difference in motion caused by the different relative speeds of the float and the vibrator to do work, and then convert the kinetic energy into electric energy to complete power generation. According to the device data and marine environment data given in the title, we sort it out. Assuming that the device will only heave or pitch in the ideal sea state, we establish the corresponding mathematical model for the device in this state, sort it out and analyze it, and finally summarize the heave and pitch motion mode and the optimal parameter setting of the occurrence efficiency of the WEC device in the ocean, and analyze and evaluate the advantages and disadvantages of the model.
