Abstract

A photovoltaic power station fault detection method, which includes: a photovoltaic cell panel infrared image generation step, obtaining infrared image information of the photovoltaic power station, obtaining infrared images of each photovoltaic cell panel according to the infrared image information of the photovoltaic power station; temperature data generation step, for each The infrared image of the photovoltaic cell panel is processed to obtain the temperature data of each cell in each photovoltaic cell panel; the fault state determination step is to compare the temperature data of each cell with the preset temperature threshold, and determine the temperature of each cell according to the comparison result. fault status. This method can realize automatic fault inspection of photovoltaic power plants. Compared with the existing detection method using manual inspection, this method uses unmanned aircraft to replace manual inspection, which greatly shortens the inspection time. The inspection time is long, and the inspection process is not affected by the natural environment such as topography.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a fault detection method for a photovoltaic power station. Background technique [0002] With the continuous development of the global economy and society, energy consumption also continues to grow accordingly. Traditional fossil energy has defects such as limited reserves and high environmental pollution. Under this background, large-scale development and utilization of renewable energy has become an important component of the energy strategy of various countries. [0003] As a clean, pollution-free, convenient and easy-to-obtain renewable energy, solar energy is increasingly favored by people. Relying on solar energy, a renewable green energy source, photovoltaic power generation has attracted the attention of governments and people of various countries in recent years. my country's solar energy resources are very rich. In recent years, photovoltaic powe...
