Meteorological station for real-time calculation of photovoltaic power station irradiation value

Abstract

The invention provides a meteorological station for real-time calculation of a photovoltaic power station irradiation value. The meteorological station comprises a communication system and an angle self-adjusting photovoltaic device connected with the communication system, wherein the angle self-adjusting photovoltaic device comprises a photovoltaic panel I and a lifting subassembly; the communication system comprises an AD (Analogue to Digital) converter, a radiation sensor, an air temperature sensor, a main control chip, a local communication circuit and a remote communication circuit, wherein the main control chip controls lifting of the lifting subassembly to perform automatic adjustment of an angle after reception of data signals of the radiation sensor and the air temperature sensorand analysis of data. According to the meteorological station dedicated for a photovoltaic power station provided by the invention, the absorption rate of the photovoltaic panel is enabled to reach avery high level by slightly adjusting an absorption angle of the photovoltaic panel; the power generation capacity is better than that of existing photovoltaic power generation equipment; the adoptedtechnical technique is relatively simple; and the meteorological station can be completed through simple modification on the basis of the existing equipment.

Description

technical field [0001] The invention relates to a weather station, in particular to a weather station for real-time calculation of the radiation value of a photovoltaic power station. Background technique [0002] Photovoltaic power generation, as a cleaner energy source, has been greatly developed and researched in recent decades. In many sunny areas in China, photovoltaic power stations are installed, which can obtain a large amount of clean energy, but photovoltaic power stations are in use At this time, since the photovoltaic panels are set at a fixed angle and cannot change directions to absorb light energy, the best power generation efficiency cannot be achieved. Moreover, since the absorption efficiency of existing photovoltaic cell components and photovoltaic inverters is greatly affected by temperature and load, the estimated output deviation is relatively large, and the statistics of power generation are also very inaccurate.

[0002] Photovoltaic power generation, as a cleaner energy source, has been greatly developed and researched in recent decades. There are photovoltaic power stations in many sunny areas in China, which can obtain a large amount of clean energy, but photovoltaic power stations are in use When the photovoltaic panel is set at a fixed angle, it cannot change the direction to absorb light energy, and the best power generation efficiency cannot be achieved.

Moreover, since the absorption efficiency of existing photovoltaic cell components and photovoltaic inverters is greatly affected by temperature and load, the estimated output deviation is relatively large, and the statistics of power generation are also very inaccurate
