Photovoltaic power generation support system capable of automatic steering according to illumination, and method

Abstract

The invention relates to a photovoltaic power generation support system capable of automatic steering according to illumination, and the system comprises a sunlight intensity collection circuit which consists of a photosensitive sensor array, a signal conditioning circuit, an A / D conversion circuit and an MCU module. The system also comprises a solar cell panel adjusting system which consists of a solar cell panel, a voltage adjusting circuit, an MCU module, an X-axis stepping motor and a Y-axis stepping motor. The system also comprises a peripheral information system which consists of an MCU module, a GPS receiver, a clock module, and a Zigbee wireless communication module. The system employs a control method which combines time control and light control, wherein the time control is taken as the principal thing, and the light control is taken as the auxiliary thing. The method comprises the steps: firstly tracking the sun through time control; secondly carrying out the precise adjustment through employing the light control. The system enables the sunlight to irradiate the solar cell panel vertically at any time, guarantees the adjustment instantaneity of the support under the condition that the number of adjustment times of the support is reduced, and improves the power generation efficiency of a photovoltaic power generation system.

Description

technical field [0001] The invention belongs to the technical field of electronic control equipment, in particular to a photovoltaic power generation support system and method that automatically turns according to light. Background technique [0002] The global energy crisis has promoted the rapid development of the new energy industry, and solar energy is the most important basic energy source among various renewable energy sources. Therefore, as a solar power generation technology that converts solar radiation energy into electrical energy, the photovoltaic industry is developing rapidly . In the old concept, the photovoltaic industry mainly includes the production chain of solar modules, electrical control components such as controllers and inverters.

Problems solved by technology

[0003] At present, in the design of large-scale photovoltaic power plants, especially in China, many solar panel arrays basically adopt a fixed structure, which is affected by the cosine effect and cannot guarantee the vertical irradiation of sunlight. The photovoltaic cells cannot make full use of solar energy resources, and the power generation efficiency is low. There is no guarantee of obtaining the maximum photoelectric conversion efficiency throughout the year
