Abstract

The invention discloses a control method of a photovoltaic tracking system, a controller and the photovoltaic tracking system. When the power generation performance influence parameter satisfies a corresponding first threshold condition, the photovoltaic tracking system is controlled to be switched from a normal tracking mode to a composite tracking mode, and the composite tracking mode is a combination of a cooling operation mode and the normal tracking mode. In the cooling operation mode, the inclination angle of the photovoltaic module is adjusted to the preset angle, so that an airflow channel is formed between the photovoltaic modules, heat dissipation and cooling of the photovoltaic modules are facilitated, and therefore the influence of the high temperature of the photovoltaic modules on the power generation efficiency is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, and more specifically, to a control method, a controller and a photovoltaic tracking system of a photovoltaic tracking system. Background technique [0002] The power generation efficiency of photovoltaic modules is directly related to the irradiation angle of the sun's rays. When the sun's rays irradiate the surface of the photovoltaic modules vertically, the photovoltaic modules receive the most solar energy, and the power generation efficiency is the highest at this time. The photovoltaic tracking system can automatically track the change of the sun's position, and adjust the inclination angle of the photovoltaic module in real time by rotating the photovoltaic tracking bracket on which the photovoltaic module is placed, so as to ensure that the sun's rays shine vertically on the plane of the photovoltaic module. Studies have shown that the temperature of photovoltaic mod...
