Device and method for tracing maximum power point of photovoltaic cell panel

Abstract

The invention discloses a device and method for tracing the maximum power point of a photovoltaic cell panel, and the device comprises a cell panel which is rotatingly disposed at the upper end of a supporting column and provided with a light sensor; and a rotary workbench which is a no-gear full-hydraulic drive rotating device and used for adjusting the azimuth of the cell panel. The supporting column is disposed on the rotary workbench. The device also comprises a hydraulic work station which is in oil path connection with the rotary workbench and supplies rotating power to the rotary workbench. The hydraulic work station drives the cell panel to rotate according to a sunlight deflection signal, so as to receive the maximum illumination intensity of sunlight. The device and method enable the cell panel to be higher in tracing precision of sunlight and to be better in instantaneity, makes the most of resources, reduces the installation cost, and greatly improves the power generation efficiency of the whole photovoltaic power station.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a photovoltaic battery panel maximum power point tracking device and a tracking method thereof. Background technique [0002] At present, there are two main installation methods of photovoltaic panels, namely fixed type and tracking type. The inclination and orientation of the fixedly installed solar panels are fixed, and the sun’s rays cannot be tracked. The required installation cost is low, but the power generation efficiency is not high. . The tracking type is divided into single-axis tracking and dual-axis tracking. The single-axis tracking system only tracks the azimuth of the sun's rays, and the dual-axis tracking system tracks the azimuth and altitude of the sun's rays at the same time. It is installed in a dual-axis tracking manner. The solar panel has the highest power generation efficiency and is a research hotspot in the field of photovoltaic power genera...
