Mounting structure of parameter measuring instrument in parallel networking type solar photovoltaic power station

Abstract

The invention discloses a mounting structure of a parameter tester, which can accurately detect real time irradiance and temperature of a solar energy photovoltaic assembly, in a grid-connected solar energy photovoltaic power station. In the mounting structure, a solar irradiance tester is mounted on a same plane of a light receiving surface of the solar energy photovoltaic assembly in the photovoltaic power station, and a temperature tester is packaged in the solar energy photovoltaic assembly. The invention can real time measure irradiance received by the surface of the solar energy photovoltaic assembly and temperature in the solar energy photovoltaic assembly, thereby providing reliable basis for accurate measurement and calculation of instantaneous electricity generation power of the grid-connected photovoltaic power station.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to an installation structure of a parameter tester in a grid-connected solar photovoltaic power station. Background technique [0002] As the supply of energy resources becomes increasingly tense and the environment worsens, the country's efforts to promote energy conservation and emission reduction continue to increase, and grid-connected solar photovoltaic power plants have been initially applied in China. [0003] Grid-connected photovoltaic power plants convert solar radiation energy into direct current through solar photovoltaic modules, which are converted into alternating current by grid-connected inverters and then incorporated into the grid. The power generation performance of grid-connected photovoltaic power plants is the main technical parameter of photovoltaic power plants. At present, the single-chip photovoltaic modules used can only be tested under ...
