Abstract

The invention discloses a photovoltaic power generation data acquisition system and method. The photovoltaic power generation data acquisition system comprises a photovoltaic module; a U / I acquisition module which is connected with the photovoltaic module, and is used for acquiring voltage and current data of the photovoltaic module, sending the voltage and current data and cutting off the photovoltaic module according to a fed-back string cutting-off instruction; a data recording module used for storing the voltage and current data; a local computer which is connected with the data recording module, and is used for judging the fault condition of the photovoltaic module according to the voltage and current data and sending a string cut-off instruction according to the fault condition; a data transmission module used for transmitting the voltage and current data to a cloud server; and the cloud server which is used for judging the fault condition of the photovoltaic module according to the voltage and current data and sending a string cut-off instruction according to the fault condition. When the circuit is in danger, a photovoltaic string circuit can be automatically cut off, so that greater risks are avoided, and the equipment and personal safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation and photovoltaic equipment testing, in particular to a photovoltaic power generation data acquisition system and method. Background technique [0002] With the increasing environmental pollution caused by fossil energy, renewable clean energy such as solar energy and wind energy has attracted much attention. Photovoltaic is an important field for the effective use of solar energy, and the use of photovoltaics is growing rapidly. At present, the instruments, methods, and accuracy required for online operation detection and measurement of key equipment in solar photovoltaic power stations are far from the international advanced level. For the actual operation performance evaluation methods, measurement equipment accuracy, and equipment The layout plan is immature, and the method of data comparison analysis and actual operation performance evaluation is single, which makes it i...
