Abstract

The invention provides a data collection device of a solar photovoltaic module array and a data processing method of the data collection device. The data collection device comprises a photovoltaic module monitoring system, wherein the photovoltaic module monitoring system comprises a photovoltaic monitoring software system, data convergence equipment and a module monitoring terminal, the module monitoring terminal is transmitted to the data convergence equipment by a local wireless communication technology, and the data convergence equipment is transmitted to the photovoltaic monitoring software system by transmission technologies such as remote communication and GPRS communication / local data network. By the data collection device of the solar photovoltaic module array and the data processing method of the data collection device, voltage and current signal quantity of the photovoltaic module is acquired and is transmitted to a background master station by a wireless mode, so that intelligent analysis, processing and management of the application condition of the photovoltaic module in a photovoltaic power station is achieved, and a set of intelligent management information platformfor photovoltaic power generation is built.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar photovoltaic module array data collection device and a data processing method thereof. Background technique [0002] Photovoltaic power generation, as an emerging green energy, has developed rapidly around the world under the encouragement of relevant government policies. By the end of 2017, my country's cumulative installed capacity is expected to exceed 127GW. With the development of technology, the cost of photovoltaic upstream continues to decline, and the later maintenance and safety of power stations have gradually attracted the attention of investors. Monitoring the power generation data and status of photovoltaic modules is of great significance to improving the actual power generation efficiency of the system and protecting photovoltaic power generation equipment. [0003] At the same time, as large-scale solar power plants begin to be built and put into o...
