Problems solved by technology

[0004] Looking at the current situation at home and abroad, the traditional data collection and statistical methods can only collect and analyze a part of the system data for a specific problem, and it is difficult to manage and re-apply the monitoring data, which cannot meet the needs of distributed photovoltaic comprehensive monitoring. requirements
The main reason is that the traditional photovoltaic monitoring method directly uploads all the data of all photovoltaic power generation units to the terminal of the monitoring system for unified analysis and processing. However, due to the high density of test points in the distributed photovoltaic power generation system, the data collection is too scattered and the number Huge, it will inevitably make it difficult for the data processing capability of the distributed photovoltaic data acquisition system to meet the requirements, and the acquisition terminal has high power consumption and poor economy

Description

technical field [0001] The invention belongs to the field of distributed photovoltaic data monitoring, and in particular relates to a distributed photovoltaic data acquisition terminal, system and data processing method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the rapid development of distributed photovoltaics in my country, the total installed capacity has exceeded 45 million kilowatts, and the impact on the operation of the power grid has become increasingly apparent. At present, the grid dispatching terminal has not yet achieved full coverage of distributed photovoltaic data access, and there are problems such as low data collection quality and accuracy, and incomplete data, which affect grid operation monitoring, power statistics and load forecasting. In order to strengthen the data collection and statistical management ...
