Intelligent control system and control method for cleaning of solar photovoltaic panel

Abstract

The invention discloses an intelligent control system and control method for the cleaning of a solar photovoltaic panel, and belongs to the technical field of solar photovoltaics. The system is composed of a meteorological data module, a data acquisition module, a monitoring unit, a robot workstation and an inspection cleaning robot. The monitoring unit is used for collecting and recording a powergeneration current and the real-time meteorological data of a power plant and comparing the power generation current and the real-time meteorological data with a normal power generation efficiency attenuation model built in the system to obtain a real state that the accumulated dust affects the power generation efficiency. Through comparing the optimal cost operation data, an optimized scheme forcleaning the photovoltaic array is obtained, and the automatic cleaning robot is controlled to automatically clean the photovoltaic panel. Compared with the prior art, the system can automatically recognize local pollution of the photovoltaic panel and automatically clean he local pollution, can effectively prolong the overall cleaning period of a solar power plant, reduces the overall cleaning frequency, prolongs the service life of the photovoltaic panel, reduces the operation cost, optimizes the cleaning period, and achieves the optimization of the power generation efficiency and the operation cost.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic technology, and relates to a solar photovoltaic panel cleaning intelligent control system and control method, in particular to a system that can not only realize the automatic cleaning of dust accumulation in the optimal cleaning cycle, but also realize the local pollution of the photovoltaic panel surface in a timely manner. An intelligent control system for discovery and cleaning and a control method thereof. Background technique [0002] Under the current technical background, the surface of photovoltaic panels is covered by dust, ice and snow, and bird excrement, which will significantly reduce the power generation efficiency of photovoltaic panels. Among them, the relatively uniform coverage of the ash accumulation on the photovoltaic panel will reduce the overall power generation efficiency but will not damage the photovoltaic panel itself. However, ice and snow or bird excrement will part...

Problems solved by technology

[0005] The purpose of this invention is to focus on the high cost of centralized cleaning of traditional photovoltaic panel dust accumulation, and the long interval between cleaning operations will reduce the power generation efficiency. However, in the prior art, the efficiency of manual inspection is low, and the coverage of fixed camera monitoring is limited. In order to achieve the deficiencies of implementation discovery and cleaning, a solar photovoltaic panel cleaning intelligent control system and its control method are proposed, which can intelligently clean local pollution of photovoltaic panels, and the cleaning cycle, power generation efficiency and operating costs can be further optimized
