Abstract

The present invention discloses a photovoltaic power station monitoring and operation integration system. The technical scheme of the invention concretely comprises the steps of: detecting generationcurrents and voltages of photovoltaic cells through a Hall sensor in photovoltaic combiner boxes and transmitting the generation currents and voltages to a processor; connecting and gathering detection modules of the plurality of combiner boxes in a RS485 communication mode to perform transmission through a wireless module; determining a photovoltaic panel fault condition through a photovoltaic panel fault rapid detection location system based on an unmanned aerial vehicle; monitoring and cleaning a photovoltaic panel through a cleaning robot carrying a dust detection sensor; locating actual positions of faults through the photovoltaic panel fault rapid detection location system based on the unmanned aerial vehicle, and sending fault information through a wireless communication module; andapplying the wireless communication network to connect each system of a power station to allow operation and maintenance work to be integrated and intelligent.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and specifically relates to omnidirectional monitoring and intelligent operation and maintenance technology of a photovoltaic power station, and in particular to an integrated system for monitoring and operation and maintenance of a photovoltaic power station. Background technique [0002] In order to alleviate the shortage of energy resources and the impact of climate change, countries around the world are gradually increasing the development and investment in the field of renewable energy. Due to its universality of resources, safety, reliability and noise-free characteristics, photovoltaic power generation has become a renewable energy that countries are competing to develop after wind power. Renewable energy power generation plays an important role in the long-term energy strategy. As of the end of 2016, the cumulative installed capacity of photovoltaic power generation ...
