Group control system of intelligent sun tracker

Abstract

The disease revealed a group control system of intelligent sun trackers. The group control system comprises a solar tracker group composed of multiple groups of solar tracking brackets, wherein each group of solar tracking bracket comprises one solar tracking bracket, a control box of the solar tracking bracket is internally provided with an extreme value searching device, a photovoltaic power output unit of the solar tracking bracket operates independently and is connected with a DC converter, and the DC converter is connected with a direct load and the extreme value searching device to form feedback of maximum power; and each group of solar tracking bracket is configured to have an annular control bus access function, an annular control bus is connected with a motor controller of each solar tracking bracket, data sharing is conducted by means of the annular control bus, and the annular control bus comprises a control end, so that the effects of acquiring the maximum output power of the solar trackers and improving performance of a photovoltaic array by the solar trackers through controlling the plurality of solar tracking brackets to rotate synchronously by using one solar tracking bracket are achieved. The group control system can be widely used in the field of solar trackers.

Description

technical field [0001] The invention belongs to the field of new solar energy, and in particular relates to a group control system of an intelligent sun tracker. Background technique [0002] During the rotation of the earth, the solar photovoltaic power generation system at a fixed location on the surface of the earth is affected by the relative motion of the sun around the earth, resulting in the change of the angle of illumination. [0003] Conventional sun trackers can effectively ensure that solar panels are always facing the sun, so that the power generation efficiency can reach the best state. At present, the working principle of the general solar tracker in the world needs to calculate the angle of the sun at different times of each day of the year according to the longitude and latitude of the placement point, and store the sun position at each time of the year to PLC, single-chip microcomputer Or in the computer, the tracking is realized by calculating the sun pos...

Problems solved by technology

And this phenomenon will not last long, resulting in the overall level of power generation not increasing, but the power consumption of the tracker becomes larger

Similarly, such control principles are not applicable in all regions or weather
