Abstract

The invention relates to a method for building an intelligent cleaning decision-making system for a photovoltaic power station, which sequentially comprises the steps of building a dust blocking loss calculation subsystem, building a meteorological forecast subsystem, building a generating capacity forecast subsystem and building an intelligent cleaning decision-making subsystem. On the one hand, a more accurate and more representative photovoltaic assembly dust blocking loss ratio is provided through monitoring the dust blocking loss ratio of a dynamic photovoltaic assembly array on the spot based on actual operation and maintenance demands of the photovoltaic power station so as to act as a data basis of decision making, so that the blindness in only relying on intuitive judgment of the operation and maintenance personnel of the photovoltaic power station can be avoided, and a cleaning decision is enabled to possess a quantitative calculation basis; and on the other hand, an automatic algorithm calculation mode is adopted, formulation of a cleaning decision is enabled to have timeliness, and a dynamic cleaning period with maximized profit is provided for the photovoltaic power station.

Description

technical field [0001] The invention relates to a method for establishing an intelligent cleaning decision-making system for a photovoltaic power station. Background technique [0002] At present, in the operation and maintenance process of solar photovoltaic power plants, there are problems such as difficult array cleaning, high cleaning costs, and difficult cleaning time. This has also led to a decrease in power generation due to the array being blocked by dust in photovoltaic power plants, and power generation revenue has not met expectations. Making reasonable and effective cleaning decisions for photovoltaic power plants and finding the dynamic optimal cleaning cycle under the premise that the cleaning cost is basically fixed is an inevitable requirement for intelligent and efficient operation and maintenance of photovoltaic power plants in the future. [0003] The cleaning decision of the photovoltaic array needs to be made according to the power generation of the powe...
