With the proliferation of massive data at power terminals, the demand for communications in low-voltage distribution networks is also increasing. Therefore, an effective wide-area, high-speed, two-way, real-time, and integrated communication system is needed. This paper studies the application of multi-mode heterogeneous communication in low-voltage distribution network. Several wired communication and wireless communication networks are combined to form a heterogeneous network to realize comprehensive perception of equipment status, efficient processing of data and information, and convenient and flexible business applications. The heterogeneous convergent network environment to realize the full coverage of the low-voltage distribution communication network has practical research value to ensure the high reliability and high security of the distribution network communication.
