Technical support method for photovoltaic power station group management

Abstract

The invention discloses a technical support method for photovoltaic power station group management. Real-time viewing of the visual cleaning effect and the hot spot fault detection result on a computer in a vehicle on the spot is realized through a photovoltaic module fallen dust clearing device, the cleaning effect and the hot spot fault detection result are synchronously transmitted to a photovoltaic power station centralized control center, and data of the assembly cleaning effect and the hot spot fault detection result of the photovoltaic power station centralized control center are sharedwith a group management platform; and the photovoltaic module fallen dust clearing device comprises a power module, a travelling module, a reverse module, a hot spot feedback module, a data interaction module and a photovoltaic power station group management technical support module. The group can view the two most important factors (fallen dust influences the energy conversion of a photovoltaicpower station, and hot spots not only does not generate power but also consume a large amount of power energy) influencing the power generation efficiency of the photovoltaic power station in real time, then the work of the power station is guided technically according to the data (power generation capacity time domain curves and power quantity integration of the cleaning effect), and the management is improved.

Description

technical field [0001] The invention relates to a photovoltaic module dust cleaning device and a working method thereof, and belongs to the technical design field of photovoltaic power station management. Background technique [0002] Through foreign research, according to NASA research, only 4.05 grams of dust per square meter will reduce the proportion of solar energy conversion by as much as 40%. [0003] figure 1 is the loss of power generation caused by dust in a photovoltaic power station in San Diego, USA. During the period from May 15th to August 29th when there was no rainfall, the loss rate of dust-induced photovoltaic power generation has been increasing, with the highest value being 22%, which also means that on August 29, about 22% of the power generation was lost due to falling dust. [0004] figure 2 is the impact value of dust on power generation in a photovoltaic power plant located in Cyprus on the east coast of the Mediterranean Sea near the West Asian...

AI Technical Summary

Problems solved by technology

[0015] Photovoltaic power stations have huge equipment, complex structures, many hidden dangers, and various hidden dangers. Therefore, there is an urgent need for a photovoltaic module dust cleaning device and a technical support method for the management of photovoltaic power station groups to provide technical support for the management of the group.

[0016] At present, there is no relevant research on the technical support methods for the dust cleaning device of photovoltaic modules and the management of photovoltaic power plant groups
