Solar photovoltaic power generation control system based on rotation axis of the Earth

Abstract

The invention discloses a solar photovoltaic power generation control system based on a rotation axis of the Earth. The system comprises a system controller, a photovoltaic module which is installed on a module shaft, a sun position sensor which is connected with the system controller and is used for transforming a tracked sun position signal into an electric signal, a first motor which is capable of adjusting the azimuth angle of the photovoltaic module under the control of the system controller, and a second motor which is capable of adjusting the high angle of the photovoltaic module under the control of the system controller. The sun position sensor comprises a tower wall, a lens barrel which is installed in the tower wall and perpendicular to the bottom of the tower wall, photoresistors which are installed on the bottom of the tower wall, and a photocell which is installed on the side face of the tower wall. The system is simple in control process and low in investment cost, and by following the laws of the movement of heavenly bodies and the rotation of the Earth, the system can effectively solve the problems of low tracking accuracy, complex control process, low anti-interference capability and the like of a conventional photovoltaic power generation system.

Description

technical field [0001] The invention relates to a control system, in particular to a solar photovoltaic power generation control system based on the earth's rotation axis. Background technique [0002] With the continuous development of society, the demand for energy from all walks of life is also greatly increasing. However, the energy content of the earth itself is limited, which makes human beings have to face the problem of energy shortage. In recent years, the use of sunlight as an energy provider has become the focus of attention, and energy conversion methods such as photovoltaic power generation and photothermal power generation have emerged one after another. However, most of the traditional forms of photovoltaic power generation systems adopt the dual-axis automatic tracking method. Although this method can realize the automatic tracking function, due to the influence of the external environment and the error of the system itself, the ideal effect is often not achi...

AI Technical Summary

Problems solved by technology

However, traditional forms of photovoltaic power generation systems mostly adopt the dual-axis automatic tracking method. Although this method can realize the automatic tracking function, due to the influence of the external environment and the error of the system itself, the ideal effect is often not achieved, and the tracking accuracy is not good. High, complex control process, low anti-interference ability, etc.
