Abstract

The disclosure provides a method, device, equipment and storage medium for determining a physical address, belonging to the field of solar power generation. The method includes: controlling at least two slave nodes to start up sequentially, detecting changes in the input voltage of the master node; dividing the photovoltaic power generation system into multiple photovoltaic strings; when the number of at least two slave nodes in the configuration data is equal, the A photovoltaic string whose number is equal to at least two slave nodes is determined as a candidate photovoltaic string; for each candidate photovoltaic string, control any slave node in the candidate photovoltaic The physical address of the PV string that inputs the voltage or current is used as the physical address of the candidate PV string. The present disclosure provides a method for automatically determining the physical address of the photovoltaic string, realizes the positioning of the photovoltaic string, expands the functional scope of the system, and can eliminate the abnormality in time when an abnormal situation occurs, and improves the system stability.

Description

technical field [0001] The present disclosure relates to the field of solar power generation, and in particular to a method, device, equipment and storage medium for determining a physical address. Background technique [0002] With the improvement of people's living standards and the advancement of science and technology, the phenomenon of energy shortage in today's society is becoming more and more serious, and the energy problem is facing severe challenges. The fundamental solution to energy problems lies in the development of environmentally friendly renewable energy. Photovoltaic power generation can convert renewable solar energy into electrical energy. It has many advantages such as adequacy and universality of resources, and has become an important development direction for energy development. [0003] see figure 1 , which shows a schematic structural diagram of a photovoltaic power generation system, the photovoltaic power generation system includes: at least one p...
