Problems solved by technology

Due to the large number of operating equipment in the photovoltaic power generation system, but lack of real-time monitoring of the system, it will be difficult for the user to solve the emergency situation of the system independently
[0004] Photovoltaic power generation equipment in operation often encounters extremely harsh conditions. If the system cannot intelligently detect faults and eliminate operational dangers in time, the service life of the system equipment will be shortened, and in severe cases, the system equipment will even be damaged.
[0005] The working state changes during the operation of the traditional photovoltaic system are relatively complicated. How to provide more suitable operation guidance for each device requires a theoretical computing system server that can predict each photovoltaic device based on the real-time operating data of the photovoltaic system.
At the same time, operators of photovoltaic power plants currently lack a platform for remote monitoring systems, and urgently need to provide a remote communication platform to solve the problem of remote monitoring in real life.

Description

technical field [0001] The invention specifically relates to a fault detection system and a detection method for remote monitoring of a photovoltaic power station. Background technique [0002] At present, the world's energy structure dominated by fossil energy such as coal, oil, and natural gas is increasingly threatened by energy depletion, and photovoltaic power generation, as a new energy technology, will surely play an important role in the future society. How to use photovoltaic power generation technology more scientifically and rationally and systematically, there is a big gap in this aspect in China. [0003] Photovoltaic power generation includes large-scale photovoltaic power plants and small household rooftop power generation systems. Due to the large number of operating equipment in the photovoltaic power generation system, but lack of real-time monitoring of the system, it is difficult for the user to solve the emergency situation of the system independently. ...
