PHYSICAL ADDRESS DETERMINATION METHOD, APPARATUS AND DEVICE AND STORAGE MEDIUM

摘要

This disclosure provides a physical address determining method, apparatus, and device, and a storage medium, and belongs to the field of solar power generation. The method includes: controlling at least two slave nodes to sequentially start up, and detecting a change status of an input voltage of the master node; dividing a photovoltaic power generation system into a plurality of photovoltaic strings; when at least two slave node quantities in configuration data are equal, determining a photovoltaic string whose slave node quantity is equal to the at least two slave node quantities, as a candidate photovoltaic string; and for each candidate photovoltaic string, controlling any slave node located in the candidate photovoltaic string to start up and other slave nodes to shut down, determining a physical address of a photovoltaic string that has an input voltage or an input current, and using the physical address as a physical address of the candidate photovoltaic string. This disclosure provides a manner of automatically determining a physical address of a photovoltaic string, thereby implementing photovoltaic-string locating and expanding a system function range. When an anomaly occurs, the anomaly can be eliminated in a timely manner, thereby improving system stability.
