An intelligent sun tracker control system and its tracking support

Abstract

A smart sun tracker control system, including a photovoltaic cell square array, a photovoltaic power output unit, a drive source, a motor controller, a power sampler and an extreme value searcher, and the power sampler collects the power signal of the photovoltaic power output unit , and send the collected power signal to the extreme value searcher, and the extreme value searcher calculates the optimal placement angle of the photovoltaic cell square array according to the received power signal, and feeds back the angle value to the motor controller; the motor The controller compares the received angle of the photovoltaic cell square array with the optimal placement angle, and then controls the drive source to drive the photovoltaic cell square array to rotate to the optimum placement angle. The present invention calculates the optimal placement angle of the photovoltaic cell square array under the maximum power through the extreme value searcher, and adjusts the angle of the photovoltaic cell square array through the motor controller according to the optimal placement angle, so that the controller can obtain the maximum Output Power. It can be widely used in the field of sun trackers.

Description

technical field [0001] The invention relates to the field of solar tracking systems, in particular to an intelligent solar tracker control system and a tracking bracket thereof. 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 computer software, tracking is achieved by calcul...

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
