Problems solved by technology

[0013] Since the current processing method does not consider the MPP voltage and MPP current after confluence, since the formation of MPP voltage and MPP current is a dynamic process, the MCU will judge the state of the fuse and whether the photovoltaic solar panel is connected during the dynamic process. Affected by the MPPT formed by the MPP voltage and the MPP current, there will be misjudgments in the process of detecting and judging the state of the fuse and whether the photovoltaic solar panel is connected

Abstract

A detection system and method based on a photovoltaic busbar, including a detection circuit one; the detection circuit one is used to detect the voltage of each photovoltaic solar cell panel and the current of each photovoltaic solar cell panel; also includes a detection circuit two, The detection circuit two is used to detect the voltage of each bus circuit and the current of each bus circuit; the detection circuit one and the detection circuit two are connected to the processing device, and the processing device passes the detection circuit one and the detection circuit Second, the data sent to determine the state of the fuse and whether the photovoltaic solar panel is connected. Combined with other structures and methods, it effectively avoids the influence of the MPPT formed by the MPP voltage and MPP current in the prior art for the MCU to judge the state of the fuse and whether the photovoltaic solar panel is connected. Misjudgment defects will occur in the process.

Description

technical field [0001] The invention relates to the technical field of photovoltaics, and also belongs to the technical field of manifold detection, in particular to a photovoltaic manifold-based detection system and method thereof. Background technique [0002] Photovoltaic: It is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. [0003] At present, the solar photovoltaic industry has become one of the most concerned emerging industries in the world today. Photovoltaic power generation is a direct power generation method that uses solar energy and semiconductor electronic devices to effectively absorb solar radiation energy and convert it into electrical energy. It is the mainstream solar power generation method today. Photovoltaic power generation does not require fuel, has no ...
