Problems solved by technology
[0002] The photovoltaic string is the most basic unit of the photovoltaic power generation system. Dust accumulation, shading, external damage, and hot spots, hidden cracks, aging, short circuit and open circuit inside the string will cause abnormal power generation, resulting in the efficiency of the photovoltaic string. too low
[0003] When locating low-efficiency strings, it is usually judged directly based on the power generation data of the PV strings, but PV strings with different power generation data are not necessarily low-efficiency strings, and other factors are not considered in this process. Factors affect the power generation capacity of photovoltaic strings, so the positioning of low-efficiency strings will be very inaccurate

Embodiment Construction
[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0055] The embodiment of the present invention provides a solution, by clustering the photovoltaic strings to determine the photovoltaic strings facing the same angle, and then individually locating the low-efficiency strings for the photovoltaic strings facing the same angle, avoiding the The misjudgment of low-efficiency strings caused by differences in the power generation capabilities of photovoltaic strings caused by different string angles and orientations improves the accuracy of locating low-efficiency strings.
[0056] Such as figure 1 as shown, figure 1 It is a schematic diagram of the terminal structure of the hardware operating environment involved in the solution of the embodiment of the present invention.
[0057] The terminal in the embodiment of the present invention is a positioning device for low-e...

The invention discloses a low-efficiency string positioning method and device and a computer storage medium. The method comprises the following steps: acquiring current data corresponding to each photovoltaic string in a photovoltaic power station; clustering the plurality of photovoltaic group strings according to the plurality of current data so as to determine the photovoltaic group strings in the same angle orientation, the current data corresponding to the photovoltaic group strings in the same angle orientation belonging to the same clustering category; and determining a low-efficiency group string in the photovoltaic group strings with the same angle orientation. According to the method, the photovoltaic strings are clustered to determine the photovoltaic strings in the same angle orientation, and then the low-efficiency strings are independently positioned for the photovoltaic strings in the same angle orientation, so that misjudgment of the low-efficiency strings caused by power generation capacity differences of the photovoltaic strings due to different angle orientations of the photovoltaic strings is avoided; and the accuracy of positioning the low-efficiency string is improved.
