Abstract

The present invention mainly relates to a method for quickly diagnosing photovoltaic module faults, collecting one or more different types of operating parameters of each photovoltaic module in a battery string within at least a preset time period; The collection of the specified type of working parameters within the preset time period is compared with the specified type of working parameters of each individual photovoltaic module in the battery string within the preset time period; Whether a photovoltaic module has an abnormal power generation event. Provide a method for rapid diagnosis of photovoltaic module faults in applications containing photovoltaic cells, which can quickly diagnose some photovoltaic modules according to actual conditions, and use this to determine the problem of the faulty module and provide a basis for providing accurate countermeasures.

Description

technical field [0001] The present invention mainly relates to the technical field of photovoltaic power generation, and to be precise, it relates to a method for quickly diagnosing photovoltaic module faults in applications containing photovoltaic cells, which can quickly diagnose certain photovoltaic modules according to actual conditions, and thereby determine faults The problem of the component thus provides the basis for providing accurate countermeasures. Background technique [0002] Energy is an indispensable resource for human production and life, and energy is also an obvious contradiction between the current actual needs of human beings and the consumption of natural resources. Along with the non-renewability of traditional chemical energy sources such as petroleum, coal, natural gas, etc., they are also increasingly depleted, which also leads to serious environmental problems such as smog and greenhouse effect. Human beings generally realize that the negative en...
