Wide-area protection peer-to-peer communication system and method based on transmission equipment ptn plane

Abstract

This patent proposes a wide-area protection peer-to-peer communication system based on the PTN plane of transmission equipment, which is characterized by: comprising more than one wide-area protection equipment, each of the wide-area protection equipment corresponds to a PTN plane; The PTN plane of the device includes an access port and a cascade port; the wide area protection device and the corresponding PTN plane are connected through the access port; the PTN planes are connected through the cascade port; each The PTN plane performs static multicast table configuration and flow control configuration according to WAN protection services. The invention completely solves the drawback of the existing power system transmission network relying too much on the dedicated E1 channel for business division, and for the wide area protection system with large scale and complex communication relationship, the efficiency of network division will be greatly improved, and the wide area protection system will be greatly improved. The system has a clear network structure, which is convenient for later maintenance and management.

Description

technical field [0001] The invention relates to communication of wide area protection equipment, in particular to a peer-to-peer communication system and method between wide area protection equipment. Background technique [0002] At present, the transmission network of the power system mainly adopts SDH (Synchronous Digital Hierarchy, Synchronous Digital System) equipment for networking. SDH equipment is based on TDM (Time-Division Multiplexing, Time-Division Multiplexing) technology for data transmission, and has a fixed service transmission bandwidth. The advantages of high reliability. However, SDH equipment networking also brings about the problem of poor flexibility. Each allocated time slot can only transmit specified services, and the allocated bandwidth cannot be used by other services regardless of whether there is information transmission, resulting in low bandwidth utilization. At present, the dispatching business, stability control business, and trustworthiness...
