Abstract

The present invention provides a floating solar power generation single-axis tracking system with low cost and high reliability and a control method thereof. The system comprises a floating power platform and an automatic tracking control system. The floating power platform autonomously rotates or moves in the horizontal dimension to automatically track solar azimuth. The automatic tracking control system comprises a satellite positioning subsystem, a shore-based ranging positioning subsystem, a sensing acquisition subsystem, a master control subsystem, and a power control subsystem. The present invention provides the control method based on the above floating solar power generation single-axis tracking system, a neural network algorithm is used to analyze floating power platform relative geographic coordinates, absolute geographical coordinates, time, a sun incidence angle, the solar azimuth and other data in real time, a best lighting position is obtained, an underwater driver is controlled to drive the floating power platform to rotate or move to a target position, and the real-time tracking of the solar azimuth by the floating power platform is achieved.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a floating single-axis tracking system for solar power generation and a control method thereof. Background technique [0002] Solar energy is a pollution-free, renewable and clean energy. [0003] Floating solar power generation devices built on water such as reservoirs, lakes, rivers and oceans can make full use of the 71% of the surface of the earth's surface sunshine area, which is conducive to the popularization and application of solar power generation technology. [0004] In the prior art, the single-axis tracking system for solar power generation has been applied to the solar power generation technology. By tracking the trajectory of the sun in real time, the amount of solar radiation received by the solar power generation device is increased, thereby improving the power generation efficiency of the solar power generation device. Traditional Taineng tracking systems ...
