Abstract

The invention discloses a photovoltaic module electromagnetic interference mechanism modeling method based on the Bissa's law, and belongs to the technical field of magnetic sensing. The implementation method comprises the following steps: through mechanism analysis of the photovoltaic module, determining that main parts of the photovoltaic module generating electromagnetic interference to the outside are a photovoltaic welding strip, an internal bus and an external bus, and combining the position relationship between the photovoltaic module and an external magnetic sensor to determine the electromagnetic interference of the external magnetic sensor. An electromagnetic interference mechanism model of a photovoltaic welding strip, an internal bus and an external bus in the photovoltaic module is established based on the Bissa's law, the relation between electromagnetic interference generated by the photovoltaic module at an external magnetic sensor and geometric parameters of the photovoltaic module and the current of the photovoltaic module is established, and the electromagnetic interference generated by the photovoltaic module to the outside is quantitatively described. And obtaining an electromagnetic interference mechanism model of the photovoltaic module. The invention is applied to the technical field of magnetic sensing, suppresses electromagnetic interference, and solves the technical problem of related engineering of electromagnetic interference suppression. The method has the advantages of being simple in modeling method, high in precision, low in cost, easy to operate and easy to implement.

Description
