24-hour-service solar photovoltaic power-generating self-tracking system

Abstract

The invention relates to a 24-hour-service solar photovoltaic power-generating self-tracking system which comprises a driving and supporting device, a solar energy collecting system, a sun azimuth tracking system and a power-generating device; the solar energy collecting system and the sun azimuth tracking system are arranged on the driving and supporting device; the solar energy collecting system collects the solar energy which is supplied for the power-generating device to generate power; the sun azimuth tracking system comprises a monitoring device, a tracking mode conversion control module and a dual-tracking mode control module; the monitoring device is used for monitoring the change conditions of weather so as to facilitate the judgment of the tracking mode conversion control module and sending out instructions to lead the dual-tracking mode control module to start relative tracking mode and control the movement of the driving and supporting device, thereby changing the position of the collecting surface of the solar energy collecting system. The system can collect the change conditions of weather in time, and control and choose the sun azimuth tracking modes according to the change conditions of weather, thereby being capable of improving the sun azimuth tracking accuracy and reducing energy consumption.

Description

technical field [0001] The invention relates to an all-weather self-tracking system for solar photovoltaic power generation. Background technique [0002] At present, as an environmental protection and new energy, solar energy has been paid more and more attention by various countries, and countries are scrambling to develop various products related to solar energy, among which solar photovoltaic power generation is the most valued one. At present, the key problem encountered by solar photovoltaic power generation is how to efficiently collect and utilize solar energy, and reduce its own loss in the process of collecting and utilizing solar energy. This involves how to accurately and effectively track the sun's azimuth and how to reduce its own loss. When tracking the sun azimuth, no matter what kind of tracking is used, the feedback to the tracking system is an electrical signal, but the actual tracking action is the mechanical structure. Due to the limitation of the cont...

However, in actual situations, it is difficult to achieve the equal torque of the upper part 16 and the lower part 17 relative to the horizontal axis 12. Usually there will be a gap, and sometimes a serious offset will occur.

When the acquisition device 11 is biased, the torque difference between the upper part 16 and the lower part 17 will damage the transmission mechanism of the transmission support device 14, resulting in a decrease in the accuracy of the transmission mechanism and affecting the rotation accuracy of the acquisition device 1; in severe cases, it will also damage the power such as the motor. parts, causing immeasurable economic losses
