Automatic tracking type solar photovoltaic power generation system and method

Abstract

The invention provides an automatic tracking type solar photovoltaic power generation system and method. The solar photovoltaic power generation system comprises a plurality of solar photovoltaic conversion panels, a tracking control device for controlling the state change of the solar photovoltaic conversion panels, and a plurality of remote terminal units in different geographical directions. The remote terminal units are communicated with the tracking control device through a field edge computing unit. After the field edge computing unit receives weather parameter information sent by a far-end centralized control platform and field state sensing signal information collected by the plurality of remote terminal units, the tracking control device generates a tracking control instruction; the state change of the solar photovoltaic conversion panels is controlled based on the tracking control instruction; and the state change comprises angle change and height change of the solar photoelectric conversion panels. According to the technical scheme, accurate control parameters can be obtained to the maximum extent, and therefore accurate automatic tracking control is achieved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation control, and in particular relates to an automatic tracking solar photovoltaic power generation system and method. Background technique [0002] Solar energy is a clean and renewable energy with large radiation, wide distribution and long availability. Therefore, solar power generation technology has been comprehensively researched and developed, but due to the shortcomings of weak solar energy, poor continuity, and instability, the efficiency of solar power generation is low and the power generation is unstable. At present, when using solar photovoltaic power generation, many solar panel arrays are basically fixedly installed in one direction, which cannot guarantee the vertical irradiation of sunlight on the solar panel, so that the solar battery cannot make full use of solar energy resources, and the power generation efficiency is low. [0003] A feasible way to solve thi...

Problems solved by technology

The closed-loop tracking system can track the sun more accurately, while the open-loop tracking system often causes errors to accumulate during the tracking process; Or the control strategy is effective. If the data collected by the relevant parameter sensors on site is not accurate enough, the obtained control strategy will not be able to achieve effective tracking control, but will reduce the power generation efficiency.
