Solar aircraft clustering optical storage power supply system

Abstract

The invention discloses a solar aircraft clustering light storage power supply system, and belongs to the technical field of light storage power supply systems. The system comprises a photovoltaic cell, and is characterized by, at least, comprising M intelligent power supply modules which output required power according to power requirements, a series-parallel connection power supply module whichis used for carrying out series-parallel connection on the N intelligent power supply modules, and an output coefficient adjusting module which is used for controlling the working state of the series-parallel connection power supply network according to the requirements of loads. The photovoltaic cell is divided into a plurality of photovoltaic cell sub-modules according to different parameter levels. Each intelligent power supply module comprises a photovoltaic power input control unit which obtains photovoltaic power based on a photovoltaic maximum power point tracking algorithm and transmits the photovoltaic power to an energy storage unit and a load; an energy storage unit which is used for storing residual photovoltaic energy on the premise of meeting the load requirement; and a poweroutput control unit which is used for realizing stable-voltage output.

Description

technical field [0001] The invention belongs to the technical field of solar aircraft power supply, and in particular relates to a solar aircraft clustered light storage power supply system. Background technique [0002] Solar-powered aircraft is an unmanned aircraft that uses solar energy as the main energy source and can fly continuously at high altitudes for a long time. Due to the advantages of high flight altitude, long time in the air, and low operating cost, solar-powered aircraft has broad application prospects in military reconnaissance, patrol early warning, high-altitude communication relay, environmental monitoring, scientific research and other fields. An important development direction of aircraft. [0003] The aircraft energy system needs to take into account the requirements of energy balance, power balance and weight balance. Energy balance means that the energy provided by the energy system is equal to the energy consumed by the flight, power balance mean...

AI Technical Summary

Problems solved by technology

The above three balance requirements make the design of the solar aircraft power supply system and the overall design of the UAV highly correlated and complex

The design of the actual solar aircraft power supply system needs to consider the constraints of power system weight and energy loss, various load characteristics, complex and changeable environmental factors, etc., which brings great challenges to the design and control of the power supply system

[0004] The typical structure of the existing solar aircraft optical storage power supply system is copied from the centralized solar storage power supply system structure of the ground grid. Although the technology is mature, it lacks flexibility
