Photovoltaic string position updating method and device

Abstract

The invention provides a photovoltaic string position updating method and device, and the method comprises the steps: obtaining the physical position of a first photovoltaic string corresponding to a first logic position in a physical map according to the physical map, wherein the physical map is used for indicating a corresponding relation between a logic position of a photovoltaic string and a physical position of the photovoltaic string in the physical map, and the photovoltaic string comprises the first photovoltaic string; and when the physical position of the first photovoltaic string in the physical map is different from the first actual physical position of the first photovoltaic string, updating the physical position of the photovoltaic string in the physical map as the first actual physical position, and obtaining an updated physical map. By implementing the embodiment of the invention, the situation that the first actual physical position of the photovoltaic string is inconsistent with the physical position in the physical map is avoided, and preparation is made for subsequent accurate operation and maintenance of the photovoltaic string.

Description

technical field [0001] The present application relates to photovoltaic technology, and in particular to a method and device for updating the position of a photovoltaic string. Background technique [0002] With the large-scale application of photovoltaic technology, the application scenarios are becoming more and more diversified. At present, in a photovoltaic power station, a solar photovoltaic module is the basic unit of a photovoltaic system (or photovoltaic device) that realizes photoelectric conversion, and can convert sunlight energy into DC power. When photovoltaic modules convert sunlight energy into DC power, the problem of low output power of photovoltaic modules may occur. Therefore, regular operation and maintenance of photovoltaic modules is required. [0003] Generally speaking, when operating and maintaining a photovoltaic module, it is necessary to first determine the photovoltaic string in which the photovoltaic module is located. However, during the cons...

Problems solved by technology

However, during the construction of the power station, the actual physical location of the photovoltaic strings may be inconsistent with the physical location on the physical map

This makes it impossible to accurately operate and maintain photovoltaic modules in the future
