Description

technical field [0001] The invention relates to a solar real-time tracking system, in particular to a solar real-time tracking system for a solar power generation system. Background technique [0002] Energy is an important material basis for the survival and development of human society. With the rapid growth of my country's economy, the demand for energy has increased significantly, and the contradiction between energy supply and demand has become prominent. While promoting energy conservation, the state also encourages the development and utilization of new energy sources such as solar energy, wind energy, and hydroelectric power. Solar energy is a clean, low-pollution new energy source, but the current utilization rate of solar energy is relatively low. At present, the photoelectric conversion efficiency of widely used photovoltaic power generation devices is only about 16%. Too low photoelectric conversion efficiency leads to high power generation cost, which is one o...

Problems solved by technology

In the prior art, the following methods are mainly used for the solar tracker: the constant voltage judgment method, the method of gradually reducing the distance between the initial state and the target state, the admittance differential method and the method based on two-dimensional PSD, the above These methods generally have disadvantages such as relatively large errors, sampling results oscillating around the maximum power point, and high prices.

At present, most solar automatic tracking systems have problems such as system complexity, poor reliability and stability, high system maintenance and operation costs, poor environmental adaptability, and low degree of automation.
