Sun tracking control method for large-scale solar power plants

Abstract

The invention discloses a sun tracking control system for a large-scale solar power station, which includes a host computer, a field control unit, a power supply unit, a controlled object for collecting solar energy, and a motor; the controlled object is provided with an inclination sensor and an optical focus sensor; the inclination angle The sensor collects the inclination information of the controlled object, and transmits it to the field control unit through the angle collector; the optical focus sensor obtains the relative position information of the sun and the controlled object, and transmits it to the field control unit; the field control unit is connected to the motor through the motor driver, The output end of the motor is connected to the tracking bracket of the controlled object; the power supply unit is set in the field control cabinet; the upper computer includes the human-computer interaction interface and the central controller, and the central controller and the field control unit are connected through wireless Ethernet or optical fiber communication connection. The invention also discloses a sun tracking control method of a large-scale solar power station, which can accurately control the inclination angle of the controlled object and realize precise sun tracking.

Description

technical field [0001] The invention relates to a sun tracking control system, in particular to a sun tracking control system of a large-scale solar power station. The invention also relates to a sun tracking control method of a large-scale solar power station, which belongs to the technical field of solar energy. Background technique [0002] For the use of solar energy, the fastest growing in recent years is photoelectric conversion, that is, solar photovoltaic power generation. In the entire solar power generation system, the angle between the sun's rays and the solar panel directly determines the output power of the panel. The higher the output power of the panel, therefore, in the process of solar power generation, the ideal state is to keep the solar panel perpendicular to the sun's rays (that is, the angle is 90°), so as to maximize the efficiency. [0003] In order to achieve the above purpose, China Patent Database published a patent titled: solar tracking system o...
