Description

Intelligent energy distribution system of ocean energy driven aircraft
Technical Field
The invention belongs to the technical field of ocean energy driven aircrafts, and particularly relates to an intelligent energy distribution system of an ocean energy driven aircraft.
Background
Compared with the conventional ship, the marine aircraft has small volume and can undertake a plurality of tasks such as marine monitoring, marine patrol and the like. But also can not carry enough energy to support self-navigation due to the restriction of the volume. However, abundant natural energy sources such as wind energy and solar energy are widely distributed in the ocean. Energy capture is very important for marine aircrafts requiring long self-sustaining power, and tasks such as monitoring and surveying in the ocean can be effectively realized only by increasing the capture capacity of external energy as much as possible and reasonably distributing the input and output of the electrical system of the whole aircraft. In actual engineering application, different marine environmental energy sources utilized by different marine aircrafts are different at present, and the solar energy, the wave energy, the wind energy, the temperature difference energy and the like are mainly concentrated. The Shu built-in (2018) indicates that the ocean surface is not covered by a covering in the current state of the technology for collecting and utilizing the environmental energy of the ocean navigation, the condition of receiving light is better, and the average solar power density is 168. Solar energy is mainly concentrated on the surface of seawater, and when the marine vehicle sails on the water surface or shallow water, the solar cell panel can convert illumination into electric energy to be stored and supplied to the marine vehicle for use. In addition, the wind energy is widely distributed on the ocean throughout the year. Zheng (2014) in the Assessment of the atmospheric wind power states that the average power density of the offshore wind exceeds 50 and is 1600 max for more than 80% of the time of the year.
The OASIS ASV3 unmanned boat invented by Emergent Space Technologies, USA, adopts the method of laying solar panels in an inclined way to improve the solar energy capturing capability for energy acquisition. The solar water surface vehicle SeaLug manufactured by the university of California, USA, Santa Luckz, adjusts the transverse inclination angle of the hull through ballast, so that the hull keeps a good illumination incident angle to ensure the effective acquisition of energy. The above optimization methods for energy harvesting are all performed from a static structure, and are not considered from an electrical structure.
The solar panel of the C-Enduro unmanned boat of the English ASV company adopts a dynamic photovoltaic array to control the capture of light energy so as to achieve reasonable configuration of the capture of the light energy, but the photovoltaic power generation system is used as a whole to charge a storage battery, the coupling influence of a wind driven generator on the photovoltaic power generation is ignored, and the energy configuration of the wind driven power generation system and a load circuit is not effectively managed.
The invention discloses a platform for detecting wind and light energy sources integrated power generation and supply on the sea, which is published in 2018, 25, 18 and has a publication number of 108054827A, and realizes complementary collection of wind and light energy sources, but the platform is only used for simply stacking and integrating various ocean energy sources, and does not reasonably configure energy input and output of a photovoltaic panel, a wind driven generator and a load.
The invention discloses a no-energy-consumption marine automatic meteorological station based on complementary energy of wave energy and light energy, which is published on 2017, 01, 25 and has a publication number of 106353839A, wherein the energy control is only to arrange a switch in a load circuit to control the output of a power supply, the input of the energy is not effectively controlled, when the voltage of a storage battery is lower than 7V, the battery stops discharging, the load stops working, the equipment cannot perform observation tasks during the period, and the real-time performance of an observation system cannot be realized.
The invention only concerns how to improve energy acquisition, and neglects the problem of use distribution at the load end. For example, considering only the effective capture of solar energy, it is important to reasonably distribute the output of energy when the energy input cannot be performed continuously in cloudy days. Therefore, the intelligent energy distributor and the algorithm for the long-endurance ocean energy driven aircraft are designed, the ocean energy driven aircraft can be guaranteed to be under different weather conditions, the energy capturing capacity is improved, the output and input distribution of the energy is reasonably carried out, and the endurance of each device of the ocean energy driven aircraft is further improved.
