Physical address determination method, device and equipment and storage medium

Abstract

The invention provides a physical address determination method, device and equipment and a storage medium, and belongs to the field of solar energy. The method comprises the steps of controlling at least two slave nodes to be sequentially started, and detecting a change condition of an input voltage of a main node; dividing a photovoltaic power generation system into a plurality of photovoltaic strings; determining the photovoltaic string of which the number of the slave node is equal to the number of at least two nodes to be an alternative photovoltaic string when at least two slave nodes inconfiguration data are equal in number; and controlling an arbitrary slave node in the alternative photovoltaic string to be started and other slave nodes to be closed with regard to each alternativephotovoltaic string, and determining a physical address of the photovoltaic string with existence of an input voltage or an input current as a physical address of the alternative photovoltaic string.The invention provides a mode for automatically determining the physical address of the photovoltaic string. By the method, the positioning of the photovoltaic string is achieved, the function range of the system is expanded, abnormality can be timely eliminated when an abnormal condition occurs, and the system stability is improved.
