Method and device for tracking control of solar electrical energy generation

Abstract

The invention discloses a method and a device for tracking control of solar electrical energy generation. The method comprises the following steps: automatically selecting a maximum power tracking mode or a timed tracking mode according to the level of the real-time output power of a solar battery; when the timed tracking mode is run, controlling tracking according to the current time and the detected current position signal of a solar panel; and when the maximum power tracking mode is run, determining the tracking direction of a mechanical structure according to the changing condition of the output power of the solar battery. The device comprises a centralized control module, a position detecting module for detecting the actual rotating position of the solar panel, and an array detecting module for detecting the real-time output power of the solar battery. The invention has the advantages of simple and convenient operation, accurate rotating position, realization of automatic control, simple structure, high detecting accuracy and low cost.

Description

technical field [0001] The invention relates to a solar power generation control method and a control device thereof, in particular to a solar power generation tracking control method and a tracking control device thereof. Background technique [0002] Solar energy is an extremely abundant green energy. Solar photovoltaic power generation can provide sustainable and clean energy for human beings, but its high power generation cost and low power generation efficiency have become important factors restricting its large-scale application. The tracking device for solar power generation can automatically track the sun and increase the daily power generation of solar cells, thereby reducing the average cost of the system. [0003] The tracking device for solar power generation is still in the initial stage of research, and its technology is far from mature. The basic principle of the existing technical solutions is: calculate the position of the sun according to the geographical ...

AI Technical Summary

Problems solved by technology

This control device has the following problems: 1. Inflexible use: the above-mentioned device can determine the position of the sun by inputting information such as local latitude and longitude angles and time, which is very inconvenient and inflexible for users

2. Poor tracking accuracy: the above-mentioned device uses a clock module to determine the actual time, which itself may have accumulated errors, and the sunshine time of each day is not exactly the same, so the calculated sun position will not be accurate, so this kind of method will lead to a large tracking error
