Abstract

The invention provides a system of measuring generating power of photovoltaic modules. The system comprises a plurality of photovoltaic modules, a photovoltaic module measurement device, a gateway, a direct current combiner box, a direct current distribution cabinet, an inverter, an environment monitor, and a data processing unit. The photovoltaic module measurement device is connected with the photovoltaic modules. The gateway is connected with the photovoltaic module measurement device. The direct current combiner box is connected with the photovoltaic modules and the photovoltaic module measurement device. The direct current distribution cabinet is connected with the direct current combiner box. The inverter is connected with the direct current distribution cabinet. The data processing unit is respectively connected with the gateway and the environment monitor and used for receiving voltage and current of the photovoltaic modules, receiving the total irradiance, direct irradiance, diffusivity, environmental temperature, module temperature and wind speed of the horizontal plane, and outputting generating power of the photovoltaic modules. The system has the advantages that the demands of the photovoltaic generating system for module operating state and generating power analysis are met, operating states and generating states of the photovoltaic modules are known timely, and generated power loss is reduced.

Description

technical field [0001] The present invention relates to the technical field of new energy exploration, in particular to the exploration technology of large-scale solar power generation, and specifically to a system for measuring the generating power of photovoltaic modules. Background technique [0002] Photovoltaic modules are the core of solar power generation systems, and the working status of each module is different in actual operation. However, the monitoring system in the prior art does not analyze the working status of the components. At the same time, due to the wide distribution and remote location of the photovoltaic power generation system, it brings great challenges to the management and communication of the components, and the management personnel cannot timely understand the working status of the components. state, failure to understand the fault in time, not only reduces the power generation, but also has potential safety hazards. [0003] The working status...
