Mainframe-control-based dedusting system for multiple cascaded solar panels

Abstract

The invention relates to a mainframe-control-based dedusting system for multiple cascaded solar panels. The mainframe-control-based dedusting system comprises the multiple solar panels. Glass protection layers are arranged on the solar panels respectively. The lower surfaces of the glass protection layers are respectively provided with a plurality of parallel electrodes, the ends of the electrodes are connected with high-voltage dedusting modules, and the adjacent high-voltage dedusting modules are cascaded. The high-voltage dedusting modules comprise high-voltage switches connected with the electrodes, high-voltage switching modules and high-voltage power supply modules. A power detection module is connected to the output ends of the solar panels, the power detection module transmits the detected power data to a digital processing and control module, and the digital processing and control module is connected with the high-voltage switching modules through an intelligent control module and is connected with a mainframe. The mainframe is provided with a real-time data processing module. The mainframe-control-based dedusting system has the advantages of being good in controllability, flexible to adjust, simple in dedusting operation and low in energy consumption.

Description

technical field [0001] The invention relates to solar panels, in particular to a dust removal system for solar panels. Background technique [0002] The glass plate on the surface of the solar panel is often prone to dust accumulation, which will lead to a sharp drop in the power generation efficiency of the solar panel and seriously affect the power generation efficiency of the solar power station. At present, the dust removal methods on the surface of solar panels mainly rely on several methods such as wind dust removal, ultrasonic dust removal, and scraper dust removal. The main disadvantages of the above dust removal methods are: the reliability of wind dust removal and scraper dust removal is not high. It is short and cannot be used in harsh environments; the disadvantages of ultrasonic dust removal are high cost and poor usability.

At present, the dust removal methods on the surface of solar panels mainly rely on several methods such as wind dust removal, ultrasonic dust removal, and scraper dust removal. The main disadvantages of the above dust removal methods are: the reliability of wind dust removal and scraper dust removal is not high. Short and unusable in harsh environments; the disadvantages of ultrasonic dust removal are high cost and poor ease of use

[0003] The electromagnetic plane dust removal device that has appeared so far uses a dust detection sensor and a pair of electrodes to apply an alternating current to the electrode by detecting the amount of dust, and the dust is removed by electrostatic force; when this dust removal device is used, due to the application of The fixed-size alternating current has poor controllability and cannot be adjusted flexibly, resulting in high energy consumption and cost. The detection accuracy of the dust sensor is not high, and the dust removal operation cannot be accurately controlled, resulting in poor dust removal effect
