The Analysis of Low-voltage Substation Business Load Capacity Based On HPLC+HRF Dual-mode Communication Technology

As the State Grid Corporation deepens the reform of the power system and constructs a new type of power system centered on new energy, the scale of low-voltage business has grown significantly with the low-voltage intelligent devices in the distribution areas. However, the existing communication systems are relatively independent among various services, lacking unified planning and optimization from the perspective of overall network carrying capacity. This paper analyzes the typical topological structure of dual-mode communication networks and the forwarding mechanism of messages on communication links, and distills a theoretical calculation formula for local communication carrying capacity. On this basis, the paper proposes a series of methods to centrally enhance the network carrying capacity, including optimizing the allocation of communication resources, improving the baud rate of device serial ports, and improving the logic of business interaction. These methods aim to achieve efficient use of communication resources and ensure the smooth progress of intelligent construction in low-voltage distribution areas.
