Title:

PHYSICAL ADDRESS DETERMINATION METHOD, APPARATUS AND DEVICE AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2019/091188

Kind Code:

A1

Abstract:

Provided in the present disclosure are a physical address determination method, apparatus and device and a storage medium, relating to the field of solar power generation. The method comprises: controlling at least two slave nodes to be powered up, and detecting a variation condition of an input voltage of a host node; dividing a photovoltaic power generation system into a plurality of photovoltaic strings; when the at least two slave nodes in configuration data are equal in number, determining photovoltaic strings in which the number of slave nodes is equal to the number of the at least two slave nodes to be alternative photovoltaic strings; and for each alternative photovoltaic string, controlling any slave node to be powered up and other slave nodes in the alternative photovoltaic string to be powered down, and determining the physical address of a photovoltaic string having an input voltage or an input current as the physical address of the alternative photovoltaic string. The present disclosure provides a method for automatically determining the physical address of a photovoltaic string, implements positioning of photovoltaic strings, expands system function range, and timely eliminates an abnormality when an abnormal condition occurs and thus system stability is improved.
