Distributed photovoltaic data acquisition and processing terminal based on Internet of Things

Abstract

The invention provides a distributed photovoltaic data acquisition and processing terminal based on the Internet of Things. A microcontroller is connected with a positioning module to obtain current position information, and the microcontroller is also in communication connection with an upper computer and is also in wireless communication with a photovoltaic power generation equipment processor to obtain photovoltaic power generation equipment operation data. The optical radiation data between the photovoltaic power generation equipment and sunlight can be monitored, various data of the photovoltaic power generation equipment can be collected and tracked, and adjustment can be carried out according to the operation state of the photovoltaic power generation equipment, so that the operation data can meet the requirements. On the basis that every day serves as a detection period, the relation between the sunlight tracking angle and the data is corrected in the current tracking period, so that the corrected tracking angle of the photovoltaic power generation equipment is within the preset tracking angle range. The tracking angle is corrected according to the power generation data of the photovoltaic power generation equipment and the actual output power, and the power generation efficiency of the photovoltaic power generation equipment is improved.

Description

technical field [0001] The invention relates to the technical field of distributed photovoltaic power generation, in particular to a distributed photovoltaic data collection and processing terminal based on the Internet of Things. Background technique [0002] With the continuous maturity and extensive construction of distributed photovoltaic power generation equipment technology, distributed photovoltaics occupy an increasing proportion in the distribution network.

Problems solved by technology

The proportion of distributed photovoltaic power generation in the power grid is increasing, which brings certain difficulties to the operation of the power grid. In particular, the output of distributed photovoltaic power generation is affected by weather factors, which brings great troubles to the load forecasting of regional power grids. Distributed photovoltaic power generation load forecasting based on data collected by distribution automation terminals and weather forecast data is subject to the scattered distribution of photovoltaic stations, and lacks the support of data such as the light radiation of each photovoltaic point, so it is impossible to understand the operating status of each photovoltaic power station, which is likely to lead to Power generation efficiency is not high
