Problems solved by technology

But there are two deficiencies in this solar tracking device for photovoltaic power generation. First, the solar tracking device for photovoltaic power generation has a large wind area in strong winds, which easily causes the entire solar tracking device for photovoltaic power generation to be damaged. The device is fixed and unstable; secondly, the tracking of the solar movement trajectory is time-controlled, and the closed-loop tracking system can track the sun more accurately, while the open-loop tracking system often causes error accumulation during the tracking process; regardless of whether it is light-controlled or time-controlled , all rely on obtaining accurate relevant parameter data to make the control model or control strategy effective. If the data collected by the relevant parameter sensor on site is not accurate enough, the obtained control strategy cannot achieve effective tracking control, which will reduce the power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic operation and maintenance control, and specifically discloses a solar photovoltaic operation and maintenance control system based on tracking control and on-site data collection. Background technique [0002] Solar energy is a clean and renewable energy with large radiation, wide distribution and long availability. Therefore, solar power generation technology has been comprehensively researched and developed, but due to shortcomings such as weak solar intensity, poor continuity, and instability, the efficiency of solar power generation is low and the power generation is unstable. In order to solve the shortcomings of existing solar photovoltaics such as weak intensity, poor continuity, and instability, most of the current solutions are to realize automatic tracking of the sun. That is to say, the solar photovoltaic power generation panel can automatically track, and its effect is simil...
